Abstract
The present invention provides a system for releasing an acid from acid precursors using an esterase enzyme (i.e., enzyme having esterase activity) as the activator.
Claims6
A detergent composition comprising:
- (1) 2 to 85% by weight of a surfactant selected from the group consisting nonionic surfactants, anionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants and mixtures thereof;
- and
- (2) an acid release system for enhancing release of acids into said detergent composition comprising:
- (a) an aromatic diacyl anhydride from which said acids are released;
- and
- (b) an esterase enzyme;
- wherein the esterase enzyme reacts with the aromatic diacyl anhydride to enhance rate of release of the acids from the aromatic diacyl anhydride.
