2 PERSPECTIVE

3 AGENDA WHY ALTERNATIVES - HISTORICAL PERSPECTIVE - REGULATORY & ENVIRONMENTAL PRESSURE - MARKET PRESSURE ALTERNATIVES - ETHOXYLATED ALCOHOLS - BIO-RENEWABLES - CATIONIC/NONIONIC BLENDS

4 HISTORICAL PERSPECTIVE APE INTRODUCTION UK IN 1940s WASTE WATER TREATMENT STUDIES BIODEGRADABILITY - NOT READILY BIODEGRADABLE TOXICITY OF DEGRADATION PRODUCTS BIOACCUMULATION ENDOCRINE DISRUPTORS

5 REGULATORY PRESSURE CANADA & EUROPE BAN CALIFORNIA STATUS

6 REGULATORY PRESSURE CALIFORNIA STATUS Table 94509(m)(3) Product Categories in which Use of Alkylphenol Ethoxylate Surfactants is Prohibited Product Category Effective Date Sell-through Date General Purpose Cleaner 12/31/ /31/2015 (nonaerosol) General Purpose Degreaser 12/31/ /31/2015 (nonaerosol) Glass Cleaner (nonaerosol) 12/31/ /31/2015 Heavy-duty Hand Cleaner or 12/31/ /31/2016 Soap (nonaerosol) Oven or Grill Cleaner 12/31/ /31/2015

7 REGULATORY PRESSURE TOXIC RELEASE INVENTORY (TRI) NP and NPE s will soon be added to EPA s new Chemicals of Concern List Under the Nonylphenol (NP) and Nonylphenol Ethoxylates (NPEs) Action Plan number [RIN 2070-ZA09]. This will begin in 2014, and result in: - Significant new use rules will be issued for these materials even in existing formulations. - The agency will add them to the list of Chemicals that companies must report under the Toxics Release Inventory (TRI)

9 US EPA DfE Program / CleanGredients The U.S. EPA's Design for the Environment program helps consumers, businesses, and institutional buyers identify cleaning and other products that perform well, are cost-effective, and are safer for the environment. Surfactants in cleaning products are distinguished by their rate of biodegradation, degradation products, and level of aquatic toxicity. The DfE Criteria for Surfactants combine these hazard characteristics, and requires that surfactants with higher aquatic toxicity demonstrate a faster rate of biodegradation without degradation to products of concern. US EPA DfE Home CleanGredients Home Acute Aquatic Toxicity (L/E/IC50 Value) 1 1 ppm Rate of Biodegradation May be acceptable if biodegradation 2 occurs within a 10-day window without products of concern 3 >1 ppm and 10 ppm Biodegradation 2 occurs within a 10-day window without products of concern 3 >10 ppm Biodegradation 2 occurs within 28 days without products of concern 3 1. In general, there is a predictable relationship between acute aquatic toxicity and chronic aquatic toxicity for organic chemicals, i.e. chemicals that have high acute aquatic toxicity also have high chronic aquatic toxicity. Since acute aquatic toxicity data are more readily available, the DfE Criteria use these data to screen chemicals that may be toxic to aquatic life. 2. Generally, >60% mineralization (to CO2 and water) in 28 days. 3. Products of concern are compounds with high acute aquatic toxicity (L/E/IC50 10ppm) and a slow rate of biodegradation (greater than 28 days). 9
