The present invention relates to a composition comprising a stable aqueous dispersion of polymer particles, an oxidoreductase, and a cofactor for the oxidoreductase and a method for its preparation. The invention is useful for converting certain classes of VOCs to non-VOCs.
Claims5
A composition comprising:
- A) a latex comprising acrylic polymer particles, styrene-acrylic polymer particles, or vinyl-acrylic polymer particles, wherein the particles have a particle size in the range of 10 nm to 1 μm;
- B) an oxidoreductase;
- and
- C) a cofactor for the oxidoreductase;
- wherein the composition has a pH of from 8 to 10 and wherein the weight-to-weight ratio of the cofactor to the oxidoreductase is from 0.5:1 to 5:1.
