Abstract
The present invention relates to detergent compositions comprising an oxidative stability-enhanced amylase and a surfactant system wherein the anionic to nonionic surfactants ratio is from 1:1 to 5:1, preferably from 1:1 to 3:1. Such compositions provide improved cleaning and stain removal performance.
Claims1
A detergent composition comprising:
- a) an oxidative stability-enhanced amylase derived from B. licheniformis NCIB8061 as the M197T variant, wherein said amylase comprises from 0.0001% to 0.01% pure enzyme by weight of total composition;
- b) a surfactant system wherein the anionic to nonionic ratio is from 1:
- 1 to 5:1 and wherein said anionic surfactant is selected from the group consisting of alkyl sulfate, alkyl ethoxy sulfate, linear alkyl benzene sulfonate and mixtures thereof;
- and
- c) a color care agent selected from the group consisting of metallo catalysts and mixtures thereof.
