## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of 2-propen-1-aminium, N,N-dimethyl-N-propenyl-, chloride, homopolymer (PolyDADMAC, CAS No. 26062-79-3) when used as an inert ingredient under 40 CFR 180.940(a) as a dispersing aid in food contact surface sanitizing solutions at less than 0.6% by weight in the final product. Scientific & Regulatory Solutions, L.L.C., on behalf of SNF, 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 PolyDADMAC.
