HCPA’s Consumer Product Ingredients Dictionary and CleanGredients Partner to Increase Offerings to Product Formulators


CHARLOTTESVILLE, VA, July 11, 2019 – The Household and Commercial Products Association (HCPA) and CleanGredients, the database of market-ready chemical ingredients pre-approved to meet U.S. EPA’s Safer Choice standard, have announced a partnership to increase information about safer ingredients in HCPA’s Consumer Product Ingredients Dictionary.
The Consumer Product Ingredients Dictionary is used by formulators of household and automotive care products as a resource for ingredient nomenclature, regulatory status, and functions, among other features. Now, users will be able to find CleanGredients-listed trade name ingredients and mixtures that contain a particular chemical in the database, then click directly to access the relevant CleanGredients profiles for more information.
A listing in CleanGredients indicates that an ingredient has been pre-screened by independent, third-party reviewers and meets the U.S. EPA Safer Choice program’s criteria. Using CleanGredients-listed ingredients simplifies the Safer Choice certification process and ensures that the ingredients are safer options for both human health and the environment.
“We are excited to partner with HCPA, both to help product formulators more easily access information about safer ingredients, and to enable chemical suppliers who have invested in developing and screening safer ingredients to gain greater recognition for their efforts,” said Elizabeth Ritch, Project Manager at GreenBlue who leads the CleanGredients program.
“Together, CleanGredients and the HCPA Consumer Product Ingredients Dictionary are helping advance the use of safer ingredients,” said Dr. Steve Bennett, Senior Vice President of Scientific Affairs at HCPA. “The Dictionary is a unified source for ingredient names required by the state of California and accepted by Walmart, Target, and the EPA Safer Choice program. Making it easy to find CleanGredients-listed ingredients in the Dictionary helps companies cut through the clutter and standardize ingredients names both on the label and online.”

Four Reasons Your Company’s Products Should Be Safer Choice-Certified

You’ve probably heard of EPA’s Safer Choice program, which recognizes household and institutional cleaning and other products that are safer for human health and the environment.  If you’re on the fence about pursuing Safer Choice certification for your company’s products, here are four of the reasons why some other companies have found participation in the program to be worthwhile:

1. Retailers love it.  


More and more, major retailers are taking action to ensure that the products on their shelves don’t contain ingredients that are harmful to their customers.  Walmart, the largest retailer in the world, specifically urges its national and private brand suppliers to certify products using Safer Choice or comparable certification programs, and will start tracking the number of products and suppliers using credible certification programs next year. They’re not the only one taking chemical safety seriously – for example, Target rolled out a new chemical strategy last year, and recognizes products certified under the Safer Choice program in its Sustainable Product Index criteria. If you’re selling products to consumers, you know how important it is to maintain a good relationship with the retailers that carry your products. A Safer Choice certification will help retailers understand that you are aligned with their chemical safety goals and take them seriously.

2. It lets you brag about your product.  

You know your product is made with ingredients that are safer for people and better for the environment, but can you safely make these claims in your advertising? In the past, companies making environmental and safety claims have run afoul of the FTC’s Green Guides when they haven’t been able to back them up.  Some companies have even been sued for claiming their products are safer than the competition. So now that you’ve put all that work into formulating a greener, safer product, how can you make sure the world knows?  Because the Safer Choice program is based on specific, transparent criteria, it helps you get out the message that your product is safer for people and the environment, without landing you in legal hot water.

3. Nothing slips through the cracks.

You care a lot about the safety of the ingredients in your products, and you know your customers do too.  You do your best to work with suppliers to make sure that raw materials meet your company’s standards before they are used in your products.  But what if your supplier says the chemicals in their product are confidential, or they don’t think to let you know about a preservative they’ve added? In the Safer Choice review process, suppliers disclose all components of their ingredients, including confidential information, residuals, and additives, to an independent third party under a non-disclosure agreement. So, you can rest assured that even the chemicals you aren’t aware of in your product are still among the safest for your customers and the environment. (As a side note, suppliers who list their products in  CleanGredients have already done the work for you,  so you can avoid surprises when you’re having your product reviewed.)

4. It’s credible.

There are a lot of products out there, making a lot of environmental claims.  Some of the claims are legitimate, others less so. Safer Choice is a program run by the federal government, with a robust, transparent set of criteria.  A Safer Choice certification cuts through confusion and greenwashing, and lets customers know that your product has undergone a rigorous review against a broad set of toxicological endpoints, as well as performance criteria.  This is more than can be said for “green” products that haven’t been certified.  As consumers are increasingly looking for safer and more environmentally-friendly products, the Safer Choice label lets them know that your product is the real deal.

A Safer Choice for Spring Cleaning

For many of us, spring cleaning is an opportunity to give our homes a deep-clean and tackle the grimy spots that don’t make it into our weekly routine. Kitchen cabinets, ovens, the outsides of windows, and the insides of cleaning appliances like dishwashers and washing machines can accumulate dirt and other crud that goes unnoticed for months or even years, so it’s important to take the time each year to make sure they get the attention they need.  
But not all of the cleaning products we use are the best for our health, the environment, or the health of others in our homes (like kids and pets).  Recent studies have found that conventional cleaning products can harm lung function as much as smoking cigarettes, and volatile organic chemicals in cleaning and other household products now contribute to outdoor air pollution as much as cars.  Many cleaning products contain chemicals that can cause asthma, which is especially a concern for products used in schools or around kids since about one in ten kids has asthma and asthma is a leading cause of school absenteeism.   

Refusing to clean isn’t a realistic option.  Never mind the dirt (and potentially resentful family members or roommates) – household dust itself can contain hazardous chemicals, such as halogenated flame retardants from furniture or electronics and phthalates from vinyl flooring.  So what can you do to keep your home sparkling while avoiding exposure to hazardous chemicals? Given the prevalence of greenwashing and the fact that most cleaning products don’t currently disclose all of their ingredients (though that is changing), it can seem daunting to make an informed decision.
Some people choose to make their own cleaning products, which in some cases can be a good (and frugal) option.  But proceed with caution – some ingredients in homemade cleaning products can also be hazardous to your health. Borax, a common ingredient in homemade laundry detergent recipes, is associated with reproductive, developmental, and neurological hazards, and some essential oils, often used to provide a natural fragrance, can cause sensitization and allergic reactions and can be harmful to pets.  Plus, some combinations of ingredients that are safe and effective cleaners on their own become ineffective when combined.  For example, when baking soda and vinegar are mixed, they neutralize each other, reducing cleaning effectiveness, and mixing vinegar with castile soap unsaponifies the soap, resulting in an oily, curdled mess.
If you’d rather leave cleaning product formulation to the experts, but want to ensure that the ingredients are safer for you, your kids, your pets, and the environment, look for products with the EPA Safer Choice label. EPA’s Safer Choice program certifies cleaning products that meet the Safer Choice Standard, and is backed up by EPA’s years of expertise in assessing chemicals and use of predictive models to assess hazards of chemicals that lack toxicity data.  To achieve the Safer Choice certification, every intentionally added ingredient in a product, including proprietary mixtures and ingredients present at a very low concentration, must be reviewed by third-party experts to confirm that the ingredients are among the safest-in-class for people and the environment.  Even if not intentionally added, known residuals from the manufacturing process present at concentrations above 0.01% must be reviewed, and residuals of concern must be reduced to the lowest feasible levels. The Safer Choice team also looks for negative synergies between ingredients in a product, to avoid reactions that could cause harm, and works with product manufacturers to support continuous improvement and innovation in the development of safer products.
Among other requirements, ingredients used in Safer Choice-certified products can’t include chemicals that are likely to cause cancer, alter genes or affect reproduction, or toxic chemicals that don’t break down in the environment and accumulate in our bodies and the food chain.  Generally, no ingredients classified as skin or respiratory sensitizers (which may cause allergic reactions after repeat exposure) may be included. Overall, formulations must meet the volatile organic compound (VOC) content restrictions set by the Ozone Transport Commission and the California Air Resources Board in order to protect indoor and outdoor air quality.  For products used outdoors, such as pressure washer concentrates, car washes, or boat washes, Safer Choice applies more stringent aquatic toxicity standards to ensure that products don’t hurt fish or other aquatic life. Plus, all products with the Safer Choice label must meet performance standards, meaning they perform at least as well as conventional products.
Safer Choice certifies products for both home and business/institutional use, in a broad range of product categories to meet needs at home, work, and school.  You can look for the label on everyday products like all-purpose cleaner, laundry detergent, and dish soap, as well as more specialized items such as appliance cleaners, descalers, and floor strippers that help you get through your spring cleaning checklist.  You can even find the label on pet shampoos and bicycle lubricants.  Fragrance free options are identified with a specific version of the Safer Choice label.  A full listing of products with the Safer Choice certification is available on EPA’s website.
Cleaning may not be the most fun way to spend a beautiful spring Saturday, but fortunately, there are safer product options that will get the job done.  Just look for the Safer Choice label and you will be on your way to a cleaner, healthier home.

Communicating Safer Alternatives Through the Supply Chain

The market for products formulated with safer chemistries is growing significantly.
There are many challenges for companies who want to develop safer alternatives. The first step is to successfully find safer substitutes for the chemicals of concern a manufacturer seeks to replace. Then there is performance testing to make sure that the finished product is as efficacious as its predecessor. Then, finally, a manufacturer has to find effective methods to market its improved products to existing and prospective customers.  Within the household and institutional cleaning products sector, CleanGredients is one way ingredient suppliers can communicate third-party verification that their ingredients are safer for human health and the environment, but some companies take it a step further and highlight their CleanGredients listings in marketing and educational materials.  These suppliers take on the role of educating their customer base about their innovations, and help product formulators find the resources they need to formulate safer products that their customers want.

Some suppliers that list in CleanGredients have made an effort to help their customers navigate EPA’s Safer Choice certification program.  For example, late last year, Stepan Company released  a product and formulation guide entitled “Navigating Safer Choice”, which makes it easy for customers who may not be familiar with CleanGredients and Safer Choice to understand which of Stepan’s home care ingredients are environmentally preferable options that meet Safer Choice criteria.  The guide identifies how each of Stepan’s CleanGredients-listed products can be used in product formulations, as well as which of their products meet other green chemistry criteria, such as bio-based content.  It also highlights Stepan’s starter formulations, which are formulations that can be used as-is for a variety of cleaning applications, or can be customized with a formulator’s colorant or fragrance, making it easy, especially for small formulators, to get a product with the Safer Choice certification to market.  Stepan has supplemented their latest guide by supporting the Safer Choice program in other ways, such as participating in webinars designed to educate other stakeholders about the program.  Their commitment to the Safer Choice program was acknowledged by EPA when they were recognized as a Safer Choice Partner of the Year in 2015 and 2017.
Other companies are also trying to educate their customers about ingredient options meeting the Safer Choice criteria  – both for ingredients used in product categories eligible for the Safer Choice certification as well as for  ingredients that meet  Safer Choice master criteria and are considered to be  safer alternatives to other options on the market.   BASF Corporation uses the Safer Choice Standard and CleanGredients as two tools in its toolkit to clearly communicate which of its ingredients are safer alternatives and to help its customers make informed decisions.  Within its Home Care and I&I Cleaning business unit, BASF’s CleanGredients Product Guide for Safer Choice Formulations identifies groups of ingredients meeting the Safer Choice standard and listed in CleanGredients, along with relevant applications in home care products and suggested formulations, making it easier for customers to formulate products that can achieve the Safer Choice certification.  But BASF has also chosen to join Eastman Chemical in listing a non-ortho-phthalate plasticizer, Palatinol® DOTP, in CleanGredients.  While this ingredient is not yet used in product categories eligible for the Safer Choice certification, because it is listed in CleanGredients, BASF can reassure its customers that it meets the Safer Choice Master Criteria and is a safer option for human health and the environment.
More and more chemical suppliers are recognizing that they have a key role to play in educating their customers and helping them select lower-hazard ingredients that will be used in end products that are safer for human health and the environment.  Listing an ingredient that meets the Safer Choice criteria in the CleanGredients database provides important third-party assurance that it is a safer alternative, but suppliers have the opportunity to go further, leveraging their CleanGredients listings to help their customers understand their options and to ultimately create safer, more effective products their customers  want.

Third-Party Certifications Help Companies Avoid Pitfalls in Green Marketing

Last month, four paint companies settled Federal Trade Commission charges that they made deceptive environmental claims, without adequate evidence to back up the claims. Among other things, the companies’ unqualified claims that their products were emission-free, VOC-free, and safe for sensitive populations got them into hot water with regulators. Paint companies are not the only ones falling into this trap. In the past, cleaning and personal care product companies have also come under fire and been subject to lawsuits for claiming that their products are natural, non-toxic, or safer than their competitor’s products.
This serves as an important reminder that, even as more and more consumers are looking for products that make “green” claims, brands need to be careful and avoid making vague assertions about their products that aren’t backed up by clear evidence. The FTC’s Green Guides provide guidance to companies to help ensure they don’t make claims that will be misinterpreted by consumers. For example, companies shouldn’t make broad, unqualified environmental claims, such as their product is “green” or “eco-friendly., They should also disclose any connections with certifying organizations if certifications or seals are used, so consumers don’t misinterpret a company’s own seals of approval as third-party certifications. So how can companies ensure that the environmental claims they make are backed up by evidence?
Third-party certifications like EPA’s Safer Choice can be incredibly valuable to companies that want to market their products based on environmental and health attributes. Participating in the Safer Choice program allows products that meet the standard to use the Safer Choice label on their package and marketing materials, indicating that the product contains ingredients safer for human and environmental health than conventional products. Every ingredient in a Safer Choice-certified product must meet EPA’s rigorous science-based criteria, and all products undergo review by independent toxicologists before they can carry the label.

Companies marketing Safer Choice-certified products find that the label is both meaningful to consumers, helping companies market their products to those looking for “green” options, and scientifically meaningful, so it stands up to scrutiny. An EPA study in February 2016 found that more than a third of consumers were familiar with the Safer Choice program and had seen the label on store shelves. After learning about the certification, more than three quarters said that the Safer Choice certification would inform their future purchasing decisions.
The market for safer products is substantial. In fact, a Consumer Reports surveyfound that 44% of the American adults surveyed would pay more for cleaning products they perceive to be safer for their health and the environment. Third-party certifications like Safer Choice can help companies access this market, without falling into the trap of making vague and unsubstantiated claims that could land them in legal trouble. Plus, consumers who see the Safer Choice label on a product will know that the claims are backed up by rigorous, independent review, so they are actually getting the safer, more environmentally friendly products they want.

Choose Safer Products to Protect Indoor Air Quality

Ah, spring. Time to enjoy the warm weather … and take on some of the cleaning tasks you’ve been putting off all winter. But did you know that the cleaning products you choose can affect the air quality inside your home?
Americans, on average, spend approximately 90 percent of their time indoors, where the concentration of pollutants is often several times higher than outdoor concentrations. This can be a particular concern for vulnerable populations, such as the very young, the elderly, or people with existing health conditions, who are both more vulnerable to the effects of pollution and may spend even more time indoors.
Indoor air pollution can come from a wide range of sources, including volatile organic compounds (VOCs) in the products you use, as well as off-gassing from building materials (like pressed wood products that can emit formaldehyde), combustion of wood or fossil fuels in fireplaces or appliances, intrusion of radon or VOCs from subsurface contamination into the building, and even mold. The problem can be exacerbated by modern building techniques, which seal the building from air leaks to promote energy efficiency, but can reduce indoor air quality if there isn’t appropriate ventilation.
Short-term and long-term health effects associated with poor indoor air quality depend on the specific contaminants present. For example, VOCs can contribute to asthma; eye, nose, and throat irritation; headaches, loss of coordination, and nausea; damage to the liver, kidneys, and central nervous system; and even cancer. Indoor air quality can also affect your cognitive function and ability to concentrate, so maintaining high indoor air quality is critical for schools and workplaces as well as homes.
So, what can you do to improve the air quality in your home? One of the easiest steps you can take is to choose safer formulated products, such as cleaning products, thereby reducing sources of indoor air contaminants.  Since many conventional cleaning products are high in VOCs and other potential air contaminants, it is important to choose safer low-VOC products to use in your home. Even cleaners made from natural materials can contribute to indoor air quality problems. For example, cleaning products that contain terpenes (e.g., pine or citrus oils) can react with ozone (either from outdoor pollution entering the building or from ozone generators sold as air cleaners) in the air within your home to produce formaldehyde, fine particulate matter, and other pollutants.

When shopping for household cleaners, look for products with the EPA Safer Choice label.  These products are required to have lower levels of VOCs to reduce impacts on indoor air quality, plus all ingredients have been screened by EPA and are safer for your family’s health and the environment. The Safer Choice program follows the VOC standards for consumer products established by the California Air Resources Board (CARB) and the Ozone Transport Commission. These agencies set VOC content limits for personal care products, cleaning products, adhesives, aerosol paints, and more based on the type of product.
Other steps you can take to improve indoor air quality include using paints and other household chemicals with low VOC content, avoiding dry cleaners that use hazardous solvents such as perchloroethylene, and avoiding new building materials such as particle board, plywood, and medium-density fiberboard (often used in subflooring, cabinets, or furniture).  If you must use these materials in your home, ensure that adequate ventilation is present. In addition, some studies suggest that houseplants can improve indoor air quality; however, their effectiveness in real-world situations is uncertain.  
Indoor air quality is a serious concern. One of the simplest things you can do to improve indoor air quality is to choose safer products that are lower in VOCs – so when you do your spring cleaning this year, look for the Safer Choice logo and enjoy the fresh air indoors and out!

A Safer Choice for Pet Care

Pets are an important part of more than half of US households, and pet owners want their furry family members to have a happy and healthy life free from exposure to hazardous chemicals. There is a growing, multi-billion dollar market for pet care products, but it can be challenging for pet owners to get a full understanding of the chemicals of concern in the products they buy, since it is uncommon for products to come with a full ingredient listing.
As a result, these pet care products can be a source of pet exposure to hazardous chemicals. Ingredients of concern may include harsh surfactants that may cause irritation or have carcinogenic effects, or thickening and pearlizing agents with poor environmental toxicity profiles. In some cases, ingredients may be even more of a concern for pets than they are for humans. Many essential oils and plant extracts fall into this category, since they can act as sensitizers when pets are exposed, resulting in allergic reactions.
Pets may also be more exposed to hazardous chemicals from household products because they tend to be smaller and closer to the ground and groom themselves using their mouths.  They also have faster metabolisms and smaller lungs than humans, so they breathe in more chemicals from the environment and process them faster. Smaller pets, like rodents and fish, can be especially vulnerable to cleaning products, including products used to clean cages and aquariums.  Like humans, pets are susceptible not only to acute poisoning by toxic chemicals, but also to diseases like cancer that can be caused by exposure to hazardous chemicals.
Fortunately, companies in the pet care sector are responding to consumer demand for safer products.  Pet owners looking for safer chemicals in the products they use to care for their pets, such as pet shampoo, can now find pet care products bearing the U.S. EPA Safer Choice label on store shelves. Safer Choice is a trusted assurance that certifies products that are safer for people, pets, and the environment, and until now, has been used primarily to label household and institutional and industrial cleaning products.  Pet owners can find Safer Choice-labeled products intended to be used directly on pets, such as pet shampoo, as well as cleaning products used in the home, in order to ensure a safe and healthy environment for their pets and the rest of their family. Like all Safer Choice-labeled products, all ingredients in pet care products with the Safer Choice label have been screened by third party profilers and EPA, assuring they are safer for both the environment and human and animal health.
pet shampooBefore making the Safer Choice label available for this new category of products, EPA evaluated conventional chemistries in the pet care sector. They looked at ingredients of pet care products that have been disclosed publicly, and reviewed existing data on the hazards associated with these chemicals. In order to ensure that their standards for pet care products were protective for pets, the Safer Choice team also spoke with stakeholders, including veterinary toxicologists, and conducted research to determine if any of the chemicals used in pet care products are particularly toxic to dogs and cats.
The first products in the pet care category to be labeled with the Safer Choice label are two pet shampoos from ECOS for Pets! by Earth Friendly Products – one fragrance free and one peppermint-scented, currently being sold in pet supply stores and at www.ecos.com. Earth Friendly Products has produced pet care products since it was founded in 1967, but is now better known for its household cleaning products. The company formulates its pet care line to the same safety and sustainability standards as its home care line, because it takes the view that pets deserve the same high standards as the rest of the family when it comes to the chemicals we use on and around them.
Matt Arkin, Director of Pet Sales with Earth Friendly Products, said

“As a long time partner of the Safer Choice program, we were so excited about the opportunity to create ECOS for Pets! and offer the first certified pet products. There are so many options for consumers and just as much confusion as to what green means that making a good decision can be overwhelming. The Safer Choice seal will provide clarity for those who want to make the best choices for their pets’ health. It is the pre-eminent third party certification and consumers can feel confident that ECOS for Pets! was formulated to the most exacting standards.”

The ECOS for Pets! products were not tested on animals, which presented a bit of a challenge for the performance testing required by the Safer Choice program. Instead of testing the performance of these shampoos on live animals, alternative performance tests were developed.  With some outside-the-box thinking and the use of many faux fur swatches, Earth Friendly Products was able to complete the performance testing required for the Safer Choice label and ensure the efficacy of its  products. Other than this hiccup, the process of obtaining the Safer Choice label on these products was smooth, in large part because the products were already formulated to the Safer Choice program standards.
Because pets roll in mud, track in dirt, shed fur, spill their food and water, and have the occasional accident, pet owners need safe and effective pet care and cleaning products.  Because EPA reviews all Safer Choice products to ensure that they are safer for pets, as well as humans and the environment, it is easier for consumers to feel confident that they are making a good decision regarding the products they purchase. Safer Choice-labeled products, including all-purpose cleaners, carpet cleaners, deicers, floor care products, pet stain and odor removers, toilet bowl cleaners, and upholstery cleaners are great options for pet owners to clean up after their pets while also keeping them safe and healthy.

Preservatives: A Challenge for Green Chemical Formulators

Preservatives are an essential ingredient for most household and personal care products, but can also be a challenge for manufacturers looking to minimize chemical hazards in their products.

Consumers expect the products they buy to maintain quality and usability for months after purchase, if not longer. Microbial contamination can negatively affect both the stability and the performance of a formulation. For example, microbes can generate acidic byproducts that affect the pH of the formulation, potentially reducing cleaning efficacy. Microbial growth can also have aesthetic effects by changing the odor or color of the formulation. Finally, microbial growth can present a health risk for users of the product (particularly for vulnerable populations), and can result in product recalls. To meet consumers’ expectations, the formulation of most household and personal care products requires the use of preservatives to protect against microbial contamination.
The susceptibility of a product to microbial contamination depends on a number of factors.  Microbes may be introduced into a product either during the manufacturing process (even when good manufacturing practices are used) or during use of the product by the consumer. Water is essential to the growth of microbes and is present in many household and personal care products, and ingredients in many products (such as surfactants or fragrances) can serve as food for microbes.  Microbial growth also depends on a product’s pH; bacteria can typically grow at pH 4 to 9, while fungal growth typically occurs at a pH of 3 to 10. However, microbes can also grow outside this pH range if they are acclimated to a manufacturing environment. Today’s environmentally-friendly products are more likely to be water-based and have lower levels of volatile organic compounds (VOCs) and heavy metals, so they are more potentially susceptible to microbial contamination. Plus, use of readily biodegradable surfactants often made from plant sugars can increase microbial activity, increasing the need for preservation.. Because of this susceptibility, preservatives are used in almost all liquid household and personal care products.
A number of preservatives have recently come under scrutiny, with regulatory bans and restrictions as well as consumer, NGO, and retailer pressure to eliminate their use. Examples include the category of compounds known as parabens, which have been criticized as potential endocrine disruptors, and compounds that release formaldehyde, a human carcinogen. In light of the concern consumers have about potentially hazardous preservatives in household and personal care products, businesses are taking note. Companies are taking steps to disclose the preservatives they use — for example, in December 2016 Procter & Gamble released a new preservative tracker, and in recent years Johnson & Johnson took steps to remove parabens and formaldehyde-releasing compounds from certain of its products.  
These increasing pressures and restrictions reduce the selection of preservatives available to formulators of household and personal care products.

Some preservatives used in lieu of parabens or formaldehyde-releasing compounds are potentially allergenic, and overuse of these in multiple products can lead to sensitization and allergic reactions.

For example, methylisothiazolinone was named the “Allergen of the Year” by the American Contact Dermatitis Society in 2013, and will be restricted for certain cosmetic applications in the EU in 2017.
Cosmetics
As a result, there is a need for manufacturers to identify new, safe, and effective preservatives. Preservatives are by definition toxic to bacteria and fungi, so identifying alternatives that are effective in controlling a broad spectrum of microbes while being non-toxic to humans and the environment is a challenge. Natural alternatives to conventional preservatives, such as essential oils, plant extracts, and organic acids, are sometimes used, and may have more favorable toxicological profiles. For example, a number of organic acids are listed on EPA’s Safer Chemical Ingredient List (SCIL) with a full green circle designation, indicating that they have been verified to be of low concern based on experimental and modeled data. However, these compounds are not appropriate for use as preservatives in all formulations. For example, organic acids are useful at a pH range of 2 to 6 and are effective against fungi and a subset of bacteria. They are not effective against all bacteria and have limited use as preservatives in alkaline products such as all purpose cleaners and laundry detergents. Therefore, broader spectrum preservatives and preservatives effective at an alkaline pH are needed for some formulations, even though in some cases the only suitable options may have some hazard concerns such as the potential for sensitization.
Few new preservatives are currently being developed, due in part to the high cost and regulatory hurdles in place. For example, the EU Cosmetics Regulation bans marketing animal-tested ingredients for cosmetics, requiring alternative safety testing methods which may not be available for all endpoints. In the US, preservatives are regulated as antimicrobial pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), requiring extensive and costly efficacy and toxicity testing.
The Green Chemistry & Commerce Council (GC3) has recognized the need for new, safer preservatives, and launched its Preservatives Project with two stated goals:

  1. To accelerate the commercialization of new, safe, and effective preservative systems for personal care and household products; and
  2. To create a new model of pre-commercial collaboration whereby companies with common needs for new, safe chemicals, materials, or other technologies, can accelerate the development and scale-up of these technologies.

Through this initiative, GC3 has developed criteria for safer preservatives and in 2016 launched a preservatives competition to motivate research and development of safer preservatives.  The initiative has earned the support of major retailers such as Walmart and Target, which participate in the organization’s Retailer Leadership Council, as well as a number of chemical manufacturers and manufacturers of household and personal care products hoping to find safer ingredients for their products.
Preservatives remain essential to maintain the quality of most household and personal care products, but are a challenge for companies looking to eliminate hazardous ingredients from their formulations. Chemical suppliers have an opportunity to develop and introduce  innovative solutions, since demand for preservatives in products will continue even as consumers become increasingly aware of the hazards posed by many existing preservatives.

Stepan Company Offers CleanGredients-approved Starter Formulations

Stepan Company, a long-term supplier who showcases its ingredients on CleanGredients, strives to offer safer solutions to its customers. One example of Stepan’s commitment to offering the market innovative and safer ingredients is its development of seven “starter formulations” that have undergone internal stability and performance testing, and also meet the U.S. EPA Safer Choice certification requirements.
Stepan developed these products to help those who are either unfamiliar with the U.S. EPA Safer Choice Program or lacked the time, money, or resources to develop and certify their own formulations. These starter formulations allow Stepan to share learnings and insights gained from years of experience working with its third-party profiler and the U.S. EPA in formulating greener products.
Formulators who are looking for flexibility can access Stepan’s full range of ingredients listed in CleanGredients and select the ingredients custom to their formula. However, those who may be less familiar with the U.S. EPA Safer Choice Program’s product review and approval process can significantly simplify matters by using one of Stepan’s seven approved, finished formulations. They are available for a variety of household and institutional cleaning applications, as identified below.
screen-shot-2016-11-14-at-1-14-38-pm
Because the starter formulations have already been tested and reviewed in compliance with U.S. EPA Safer Choice standards, time to market for a Safer Choice-certified product is dramatically reduced for formulators and may offer them an opportunity to extend a product line with reduced overhead cost. The formulations take the guesswork associated with ingredients or residuals of concern out of the equation. And because Stepan has already incurred the costs associated with individual ingredient review, use of the starter formulations takes these costs out for the product formulator as well.
Stepan has a long history of involvement with the U.S. EPA Safer Choice Program and CleanGredients:

  • The company was a key stakeholder in the development of the first ingredient screen for surfactants.
  • In 2006, Stepan Company listed its first five ingredients in CleanGredients. Since that time, Stepan has listed a total of 30 surfactants in continued support of all who seek Safer Choice certification.
  • The company recently re-certified its seven starter formulations for another three years.

When asked her advice for companies looking to formulate greener products complying with the Safer Choice standard, Anne Gariepy, Stepan’s North America Technical Service and Sales Development Manager, said, “If you have questions, engage your third-party profiler and the U.S. EPA prior to formulation development. They are very open, approachable and willing to offer advisement. It will benefit all parties. Second, engage multiple stakeholders within your own organization in continued effort to educate and achieve alignment on the activities that have the greatest impact on an organization’s overarching sustainability goals.”

Maximum Use Levels and Direct Release Reviews in CleanGredients Provide Additional Value for Product Formulators

Did you know that CleanGredients not only lists pre-approved ingredients for Safer Choice formulations, but also provides valuable information on how a given ingredient can be used in Safer Choice products? Both maximum use levels and reviews of ingredients for direct release to the environment can help formulators select the most appropriate ingredients for their formulations.

Maximum Use Levels

If an ingredient is listed in CleanGredients, it does not necessarily mean that the ingredient can be used at unlimited concentrations in a product carrying the Safer Choice label. In fact, maximum use levels may apply to ingredients listed in CleanGredients used for Safer Choice products. Formulators should keep these in mind to avoid surprises during the final review by EPA for approval to carry the Safer Choice label on their products.

Some of the ingredient profiles in CleanGredients contain a posted “Maximum Use (%)”, indicating the maximum concentration at which the ingredient may be used in a Safer Choice product, typically due to unavoidable residuals or impurities of concern that cannot be reduced with current manufacturing best practices. The Safer Choice Program reviews all such residuals and impurities, and in some cases will approve a listing with a maximum use level to keep all unavoidable residuals and impurities of concern below 0.01% in the finished product as sold. In the following example of a chelating agent, the ingredient has a calculated maximum use level of 10%, even though the active ingredient meets the Safer Choice criteria:

Direct Release

Some products are intended for use in applications that result in immediate release to the environment, bypassing sewage treatment plants or septic systems and shortening the time available for degradation prior to entering the environment. Some examples of direct release products include home car washes, boat cleaners, and graffiti removers. In order to protect sensitive environments and aquatic life, EPA’s Safer Choice program has more stringent criteria for ingredients in direct release products. Any ingredients with aquatic toxicity values <10 mg/L are not allowed in Safer Choice direct release products. Furthermore, biodegradation must occur within a specified time frame and without degradation products of concern for the ingredient to be approved for direct release.
So, how can a formulator know whether an ingredient meets the more stringent criteria for direct release products? Fortunately, most ingredients listed in CleanGredients have already been evaluated against the Safer Choice criteria for environmental toxicity and fate for chemicals in direct release products. You can check an ingredient’s direct release approval status right on the main ingredient listing page or on any individual ingredient profile, and can sort the list of ingredients by direct release approval status, making it easier to find approved ingredients in a given functional class for your direct release products.

The Takeaway for Product Formulators

Formulators can use the information on maximum use levels and direct release approvals when designing products for the EPA Safer Choice Label to ensure that they don’t end up with too high a concentration of residuals or impurities of concern or ingredients with excessive aquatic toxicity for direct release products. Other sources of Safer Choice ingredient information, including the EPA Safer Chemical Ingredients List (SCIL), don’t include information on maximum use levels or direct release approvals. By including this information, CleanGredients provides additional value, takes the guesswork out of obtaining the Safer Choice label, and reduces risk for formulators.
