## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of C10-C18-Alkyl dimethyl amine oxides herein referred to as ADAOs when used as inert ingredients (surfactants/foaming agents) in antimicrobial pesticide formulations applied to food-contact surfaces in public eating places, dairy- processing equipment, food-processing equipment and utensils, limited to not more than 1,350 parts per million (ppm) at the end-use concentration in pesticide formulations. Technology Sciences Group Inc. on behalf of Mason Chemical Company submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an amendment to an existing requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of ADAOs when used in accordance with this exemption.
