2 Outline Introduction to the Safer Choice program Appeal of the label Safer Choice-certified products Product review process Safer Choice Standard Ingredient criteria & review Safer Chemical Ingredients List (SCIL) CleanGredients 2

3 A voluntary EPA ecolabel program that draws on EPA expertise to evaluate the potential hazards of ingredients in chemical-based products Focus on safer chemical ingredients With provisions for performance, packaging, and ingredient disclosure Verifies and reviews all ingredients up the supply chain Encourages green chemistry chemical manufacturers product manufacturers retailers consumers & purchasers 3

4 What does the Safer Choice label mean? Verification by a trusted government agency that products contain only chemical ingredients meeting Safer Choice criteria, and in so doing they: Are safer for families, pets, communities, and the environment Are safer for workers and work places Perform An appealing label that customers can trust Facilitates rapid decision-making 4

5 Market Demand for the Safer Choice Label Consumer Reports (May 2015): Consumer Reports dedicated a full page to the Safer Choice label, explaining why we like the label Survey by a Leading Retailer: Majority of consumers responded that the new label would be a compelling reason to try a product 5

6 Survey of 2,000+ U.S. Adults 35% of consumers say they have seen the Safer Choice label on store shelves. 76% of consumers 83% of parents... 86% of millennials responded that they would use the Safer Choice label to inform purchasing decisions. 76% are likely to use the label to help make purchase decisions 6

10 The Standard Behind the Safer Choice Label To use the label products must: Meet the Safer Choice Standard Every chemical ingredient is reviewed for human health and environmental safety Product level requirements include: performance, packaging, and ingredient disclosure Be covered under a Partnership Agreement between the manufacturer and EPA Renewed every 3 years Undergo annual audits 10

11 Safer Choice Standard Requirements products must meet to earn the Safer Choice label: Company Level Product Level Ingredient Level Partnership Agreement (renewed every 3 years) Annual audits Ingredient disclosure Performance testing VOCs, ph, & synergistic effects Packaging Master & Functional Class Criteria 11

12 Ingredient-Level Criteria Functional-class criteria Chelating and sequestering agents Colorants, polymers, preservatives, and related chemicals Enzymes and enzyme stabilizers Fragrances Oxidants and oxidant stabilizers Processing aids and additives Solvents Surfactants Master criteria 12

13 Ingredient-Level Criteria Every chemical is evaluated per ingredient class criteria (colorants, surfactants, etc.) No de minimis for added ingredients Impurities, residuals, preservatives, & stabilizers are all considered Every material, including fragrance material, must be disclosed and meet criteria 13

14 Ingredient Review Process A Safer Choice toxicological profile for a single chemical ingredient includes data on: Physical-chemical properties Toxicity information on required endpoints Human Health Effects Carcinogenicity Mutagenicity Reproductive & developmental toxicity Neurotoxicity Repeated dose toxicity Skin irritation Environmental Fate & Toxicity Persistence Bioaccumulation Degradation products Eutrophication Aquatic toxicity 14

15 Ingredient Review Process (cont.) Steps for data retrieval and estimation: 1. Full literature review including toxicology and chemistry studies 2. Identification of analogs, metabolites, and potential degradation products 3. When experimental data is not available for a chemical: Model predictions: EPA s EPISuite, ECOSAR, & OncoLogic Read across from analog chemicals Modeling information can be found at: 15

16 Acute Mammalian Toxicity Criteria Example For acute mammalian toxicity, data must demonstrate that chemical toxicity thresholds are above cutoff values 16

17 Safer Choice Environmental Criteria Example 17

18 Going beyond lists 2-Butoxyethanol Frequently included in lists of solvents of concern Cal/OSHA Hazardous Substances List Human health concerns include hemolysis leading to toxicity in kidney, spleen and liver. Not allowed in Safer Choicecertified products 2-Propoxyethanol Not widely recognized as a solvent of concern Not on Cal/OSHA Hazardous Substances List Similar human health concerns including hemolysis leading to toxicity in kidney, spleen and liver. Not allowed in Safer Choicecertified products 18

19 Safer Chemical Ingredients List (SCIL) Living list of 900+ safer chemicals, arranged by functional use, that meet EPA s Safer Chemical Criteria Continually expanding by ~100 chemicals/year Uses Research whether proposed formulations might be eligible for Safer Choice Sustainable chemistry measure for products not carrying the Safer Choice label Highlight innovation and meet demand for safer chemicals SCIL can be a source of low-priority substances under TSCA 19

20 Safer Chemical Ingredients List (SCIL) (cont). 918 chemicals & 987 listings on SCIL as of October 2017 By functional ingredient classes: -Antimicrobial Actives (7) -Chelating Agents (22) -Colorants (44) -Defoamers (12) -Emollients (26) -Enzymes & Enzyme Stabilizers (30) -Fragrances (152) -Oxidant & Oxidant Stabilizers (19) -Polymers (59) -Preservatives & Antioxidants (34) -Processing Aids & Additives (149) -Skin Conditioning Agents (46) -Solvents (67) -Specialized Industrial Chemicals (14) -Surfactants (282) -Uncategorized (24) 20

27 Introduction: ACS Green Chemistry Student Chapters Activity Formulate your own hand soap using the Safer Choice Criteria Cleaning products are everywhere and are used multiple times a day. Whether it s washing your hands, cleaning dishes, washing clothes, or disinfecting surfaces, we interact with them on a daily basis. But what are the ingredients that make cleaning possible? Have you ever taken the time to look at the label on the back of the container? Chances are you haven t. If you have, do you understand everything that is written and know the function of every chemical ingredient that makes up the composition of liquid hand soap? As future chemists, possibly in the personal care industry, you will be responsible for understanding the functions and uses of chemical ingredients. These chemical ingredients will be the building blocks for the products you will help to formulate. So, wouldn t you want to know if there any chemicals you should avoid using? Green Chemistry is important in the design of future innovations and technologies because its principles offer a way to create new products (i.e. household soap/cleaners) that minimize risk while still offering superior performance and lower costs. More specifically, one can use Green Chemistry thinking to reduce the risk of adverse human and environmental health effects in next generation household cleaners by purposely reducing the hazards associated with products and processes. Green Chemistry offers a competitive advantage by facilitating the development of less hazardous products at the design phase!

28 After participating in the Safer Choice Webinar, you now are aware that some of the ingredients found in the cleaning products you use might have potential adverse effects to human and environmental health. YIKES! However, through the efforts of EPA, there are methods and resources to identify better alternatives that eliminate the possibility of future adverse effects. For this student chapter activity, you will be putting your Green Chemists hats on to investigate and research better alternatives for cleaning products! Activity #1: Formulate a Safer Choice Consumer Product As a student chapter, you will apply the information you learned in the Safer Choice webinar and creatively attempt to formulate your own liquid hand soap based upon the Safer Choice Ingredient List. Utilize the list to develop a formulation that would meet the Safer Choice Standard. At a basic level, liquid hand soap formulations can be narrowed down to the following ingredients: 1. Water 2. Surfactants & Emulsifiers 3. Colorants/dyes 4. Fragrances 5. Skin Conditioning Agents 6. Antimicrobial additives Using this as a mere guideline, use all available resources at EPA Safer Choice and develop a formulation label for a hand soap with the type of ingredients that SHOULD be in cleaning products. All Safer Choice certified products facilitate a more transparent labelling system by providing the 1) Ingredient names 2) CAS # 3) Functions of each ingredient (ex. Surfactant). Go to your local grocery store and take pictures of product labels for certified Safer Choice cleaners. Then as a student chapter, create an effective and elaborate formulation label for YOUR proposed liquid hand soap. Remember, the more creative the better!

29 However, this wouldn t be a Green Chemistry activity if we didn t try to better understand the hazards associated with specific ingredients found in hand soaps. So each student chapter will perform a comparison study of your proposed Safer Choice hand soap vs. a non certified Safer Choice hand soap (Hint: When searching for Safer Choice labels at the grocery store, find a non certified Safer Choice product and use it for this comparison study). Look at all ingredients listed in each formulation and retrieve all obtainable SDS. From the SDS, identify all the corresponding GHS hazards and record them. A description of GHS pictograms and hazards can be found at the end of the document. Once all GHS hazards have been identified and listed, compare the results and conclude why YOUR Safer Choice formulation is better. Below is an example of a template to perform and analyze your results. Name of Product Ingredient Name CAS Function Hazards Category (physical, human, or, environmental) Activity #2: Be an Advocate for Safer Choice! With new information on what type of products SHOULD be in your hand soaps, take the initiative to research what type of ingredients are used in the hand soaps at your university, laboratories, and department restrooms. Then create flyers that discuss the added benefits of Safer Choice products and advertise potential safer choices around your chemistry department (with permission from chemistry department head).

30 Submitting your Work ACS Student Chapters: For this event to qualify as one of your green chemistry activities at least six people must view the webinar and participate in this activity.
