## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of poly(oxy-1,2-ethanediyl), [alpha]-(3- (1,3,3,3-tetramethyl-1-((trimethylsilyl) oxy) disiloxanyl) propyl)- [omega]-hydroxy- (CAS Reg. No. 67674-67-3) when used as an inert ingredient (surfactant) applied to animals. Exponent, on behalf of LNouvel, Inc., submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of poly(oxy-1,2-ethanediyl), [alpha]-(3-(1,3,3,3-tetramethyl- 1-((trimethylsilyl) oxy) disiloxanyl) propyl)-[omega]-hydroxy- when used in accordance with the terms of the exemption in EPA regulations.
