Enzyme composition comprising enzyme containing polymer particles

摘要

The present invention relates to an enzyme composition comprising enzyme containing polymer particles, which is useful for detergent compositions, in particular for liquid detergent compositions. In these enzyme containing particles, the particles comprise i) at least one enzyme, and ii) at least one polymer P, which is selected from homo- and copolymers having a C—C-backbone, wherein the C—C-backbone carries carboxylgroups, which may be present in the acidic form or in the neutralized form, and wherein the C—C-backbone comprises hydrophobic repeating units.

1. A detergent composition, which is a liquid detergent composition and comprises an enzyme composition comprising enzyme particles, wherein the particles comprise
i) at least one enzyme, and ii) at least one polymer P, where the polymer P is a copolymer having a C—C-backbone, wherein the C—C-backbone carries carboxyl groups, which may be present in the acidic form or in the neutralized form, and wherein the C—C-backbone polymer P comprises at least 20% by weight, based on the total weight of the polymer P, of hydrophobic repeating units derived from a monomer B, wherein volume average particle diameter of the enzyme particles is from 50 nm to 100 μm, wherein polymer P comprises a) a polymerized unit A of at least one monoethylenically unsaturated C3-C8mono-or dicarboxylic acid (monomer A), wherein the polymerized unit A is a unit of polymerized monoethylenically unsaturated C3-C8-mono- or dicarboxylic acid selected from the group consisting of methacrylic acid, maleic acid, itaconic acid, crotonic acid, and a mixture thereof; and b) a polymerized unit B of monomer B, wherein monomer B has a water solubility of at most 30 g/l at 25° C. and comprises a C2-C50-olefin, or a combination of a C2-C50-olefin with at least one additional monomer B selected from the group consisting of a vinylaromatic compound, a C2-C50-alkylester of C3-C8-monocarboxylic acid, bis-C1-C50-alkylester of C4-C8-dicarboxylic acid, N—C2-C50-alkylamide of C3-C8-monocarboxylic acid, N—C1-C50-alkyl-N—C1-C50-alkylamide of C3-C8-monocarboxylic acid, vinylester of C2-C50-alkanoic acid, vinyl-C1-C40-alkylether, N—C1-C40-alkylimide of maleic acid, and a mixture thereof wherein polymerized unit A is in a molar amount relative to monomer B from 1:20 to 10:1.
