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

Document 2026-06953 is a Final Rule published by the Environmental Protection Agency in the Federal Register on April 10, 2026, with an effective date of April 10, 2026. 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.
