This regulation establishes an exemption from the requirement of a tolerance for residues of polymers produced by the reaction of either 1,6-hexanediisocyanate; 2,4,4-trimethyl-1,6-hexanediisocyanate; 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethyIcyclohexane (isophoronediisocyanate); 4,4'-methylene-bis-1,1'- cyclohexanediisocyanate; 4,4'-methylene-bis-1,1' benzyldiisocyanate; or 1,3-bis-(2-isocyanatopropan-2-yl)benzene with polyethyleneglycol and end-capped with one or a mixture of more than one of octanol, decanol, dodecanol, tetradecanol, hexadecanol, octadecanol, and octadec-9-enol or polyethyleneglycol ethers of octanol, decanol, dodecanol, tetradecanol, hexadecanol, octadecanol, and octadec-9-enol (also known as polyurethane-type polymers), when used as an inert ingredient in a pesticide chemical formulation. Syngenta Crop Protection, LLC submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of polyurethane-type polymers on food or feed commodities.
