Amended Tolerance Exemptions for Encapsulating Polymers

This document amends the tolerance exemptions for three encapsulating polymers, poly(vinylpyrrolidone-1-eicosene), poly(vinylpyrrolidone-1-hexadecene), and vinylpyrrolidone-vinyl acetate copolymer, to remove language not directly related to the inert ingredient exemption and to replace the specific tolerance exemption listings (40 CFR 180.1104, 180.1105, and 180.1106, respectively) for these polymers with general listings under 40 CFR 180.1001(c). International Specialty Products requested these changes. The Agency is also amending a similar tolerance exemption for cross-linked polyurea- type encapsulating polymer in 40 CFR 180.1001(d) to add additional language to specify the reaction products and to remove the specific tolerance exemption (40 CFR 180.1039).
