Residues of Quaternary Ammonium Compounds, N-Alkyl (C12-18) dimethyl benzyl ammonium chloride on Food Contact Surfaces; Exemption from the Requirement of a Tolerance

This regulation establishes an exemption from the requirement of a tolerance for residues of n-alkyl (C<INF>12-18</INF>) dimethyl benzyl ammonium chloride (CAS No. 68424-85-1) on food contact surfaces when applied/used in public eating places, dairy processing equipment, and/or food processing equipment and utensils. The regulation will exempt from the requirement of tolerance residues in food resulting from contact with surfaces treated with antimicrobial solutions where the end-use concentration of active quaternary compound does not exceed 400 ppm.
