Abstract

This invention relates to compositions comprising certain glycosyl hydrolases and a fabric hueing agent and processes for making and using such compositions.

Claims

1. A laundry detergent composition comprising:

(a) a glycosyl hydrolase having enzymatic activity towards both xyloglucan and amorphous cellulose substrates, wherein the glycosyl hydrolase is selected from GH families 5, 12, 44 or 74; and

(b) a fabric hueing agent, said fabric hueing agent being selected from the group consisting of dyes, dye-clay conjugates, and mixtures thereof; and

(c) a detersive surfactant.

2. A composition according to claim 1, wherein said glycosyl hydrolase is present at a level of from 0.0005% to 0.1% and said fabric hueing agent is present at a level of from 0.00003% to 0.1%.

3. A composition according to claim 1, wherein the glycosyl hydrolase enzyme belongs to glycosyl hydrolase family 44.

4. A composition according to claim 1, wherein the glycosyl hydrolase enzyme has a sequence at least 80% homologous to sequence ID No. 1.
