40 CFR 799.5087 Docket ID Number: EPA-HQ-OPPT-2007-0531 Re: Testing of Certain High Production Volume Chemicals; Second Group of Chemicals, Federal Register 76 (5), 1067-1093, January 7, 2011; Castor Oil, Sulfated, Sodium Salt, CAS No. 68187-76-8 

### To Whom It May Concern: The U.S. Environmental Protection Agency (EPA) promulgated a final TSCA test rule on January 7, 2011 (76 FR 1067-1093) that requires manufacturers (including importers) and processors of Sulfated Castor Oil to conduct testing to obtain screening level data for health and environmental effects and chemical fate. The Sulfated Castor Oil (SCO) Consortium, a cost-sharing consortium affiliated with the Society of Chemical Manufacturers & Affiliates (SOCMA), is pleased to provide test results in response to the EPA test rule, which we believe will fulfill the rule requirements. The SCO is made up of the following U.S. manufacturers of Castor Oil, Sulfated, sodium Salt, CAS No. 68187-76-8: Afton Chemical Corporation Manufacturers Chemical, LLC Emerald Carolina Chemical LLC The SCO has conducted testing in accordance with the EPA-approved Test Plan and offers the following studies:
