Abstract
The invention concerns laundry detergent compositions comprising lipase (especially the variant D96L of the native lipase derived from Humicola lanuginosa), protease, and surfactant, wherein said compositions comprise levels of lipase enzyme and protease enzyme such that the whitening performance of said compositions is increased. These compositions deliver an improved whiteness maintenance and/or dingy clean-up on fabrics.

A laundry detergent composition comprising:
- (a) from about 0.001% to about 2% of a lipase enzyme variant D96L of the native lipase derived from Humicola lanuginosa strain D SM 4106;
- (b) a protease enzyme selected from the group consisting of the Bacillus lentus subtilisin variant N76D/S103A/V104I according to the numbering of Bacillus amyloliquefaciens subtilisin at a level to provide from 0.005 to 0.1 AU per gram of composition;
- and
- (c) from about 0.1% to about 60% of a surfactant;
- and wherein further said compositions comprise levels of lipase enzyme and protease enzyme such that the whitening performance of said compositions is increased.
