Polyethylhexyl Glycidyl Ether Polyethylene Oxide Copolymer in Pesticide Formulations; Exemption From the Requirement for a Tolerance

What it does

This regulation establishes an exemption from the requirement of a tolerance for residues of polyethylhexyl glycidyl ether polyethylene oxide copolymer (CAS Reg. No. 82780-16-3) when used as an inert ingredient (wetting agent or surfactant) on growing crops and raw agricultural commodities pre- and post-harvest limited to no more than 10% by weight of the pesticide formulation. Spring Regulatory Sciences on behalf of Ashland Specialty Ingredients G.P. 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 polyethylhexyl glycidyl ether polyethylene oxide copolymer, when used in accordance with the terms of the exemption.
