Oxirane, 2-phenyl-, polymer With oxirane, mono(hydrogen 2-sulfobutanedioate), octyl ether, sodium salt (1:2) in Pesticide Formulations; Exemption From the Requirement for a Tolerance
Key claim: EPA established a tolerance exemption for oxirane, 2-phenyl-, polymer with oxirane, mono(hydrogen 2-sulfobutanedioate), octyl ether, sodium salt (1:2) as an inert ingredient in pesticide formulations, eliminating the need for a maximum residue level on food or feed commodities.
Abstract
(Rule · Environmental Protection Agency) This regulation establishes an exemption from the requirement of a tolerance for residues of oxirane, 2-phenyl-, polymer with oxirane, mono(hydrogen 2-sulfobutanedioate), octyl ether, sodium salt (1:2) (CAS Reg. No 2983072-24-6); (also known as oxirane, 2-phenyl-, polymer with oxirane, monooctyl ether, sulphosuccinated, disodium salt) when used as an inert ingredient in a pesticide chemical formulation under 40 CFR 180.960. Spring Regulatory Sciences on behalf of Evonik 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 oxirane, 2-phenyl-, polymer with oxirane, mono(hydrogen 2-sulfobutanedioate), octyl ether, sodium salt (1:2) on food or feed commodities when used in accordance with these exemptions.
Why this matters
Tolerance exemptions for inert pesticide ingredients determine which residues can appear on food and feed commodities without a numeric maximum residue level, shaping both farmer access to formulated pesticide products and consumer exposure assumptions. Routine EPA additions under 40 CFR 180.960 incrementally expand the inventory of approved inerts, with negligible direct effect on food prices but cumulative relevance to the pesticide regulatory baseline.
