Abstract

This document establishes a generic exemption from the requirement of a tolerance for acrylate polymers and copolymers when used as inert ingredient in pesticide formulations applied on raw agricultural commodities. This tolerance exemption covers the acrylate polymers/copolymers which are intrinsically safe and already listed in the TSCA inventory or will meet the polymer tolerance exemption from requirements of premanufacturing notification. Polymers that are exempted can be used as dispensers, resins, fibers, and beads, as long as the fibers, beads and resins particle sizes are greater than 10 microns and insoluble in water. Polymers with high molecular weights (3,000 to 100,000 daltons) are generally not readily absorbed through the intact skin or intact gastrointestinal (GI) tract. Polymers with particle size greater than 10 microns are generally not readily absorbed by respiration. Chemicals not absorbed through the skin, GI tract, and respiratory system are generally incapable of eliciting a toxic response. This exemption pertains to the acrylate polymers/ copolymers used as inert ingredient for sprayable and dispenser pesticide formulations that are used on food crops. Any acrylate polymers/copolymers used for encapsulating material must be cleared as an inert ingredient when used in pesticide formulations that are applied on food crops.
