This regulation establishes an exemption from the requirement of a tolerance for residues of sodium 1,4-dialkyl sulfosuccinates including sodium 1,4-dihexyl sulfosuccinate (CAS Reg. No. 3006-15-3); sodium 1,4-diisobutyl sulfosuccinate (CAS Reg. No. 127-39-9); and sodium 1,4-dipentyl sulfosuccinate (CAS Reg. No. 922-80-5) when used as an inert ingredient in pesticide formulations for pre-harvest and post- harvest uses, as well as, for application to animals under 40 CFR 180.910 and 40 CFR 180.930, respectively. The Joint Inerts Task Force (JITF), Cluster Support Team 13 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 the sodium 1,4-dialkyl sulfosuccinates.
