2-Propenoic Acid, 2-Methyl-, Telomer With 1-Dodecanethiol, and 2-Methyloxirane Polymer With Oxirane Monoether With 1,2-Propanediol Mono(2-Methyl-2-Propenoate) in Pesticide Formulations; Exemption From the Requirement for a Tolerance

Document 2026-16123 is a Final Rule published by the Environmental Protection Agency in the Federal Register on August 7, 2026, with an effective date of August 7, 2026. This regulation establishes an exemption from the requirement of a tolerance for residues of 2-propenoic acid, 2-methyl-, telomer with 1-dodecanethiol, and 2-methyloxirane polymer with oxirane monoether with 1,2-propanediol mono(2-methyl-2-propenoate) (CAS Reg. No 1186225-21-7) when used as an inert ingredient in a pesticide chemical formulation. Spring Regulatory Sciences on behalf of Clariant Corporation 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 2-propenoic acid, 2-methyl-, telomer with 1-dodecanethiol, and 2-methyloxirane polymer with oxirane monoether with 1,2-propanediol mono(2-methyl-2-propenoate) on food or feed commodities when used in accordance with these exemptions.
