Abstract

A method for enhancing the detergent properties of enzymes of an enzyme-containing detergent composition, comprising the step of adding to said composition an amphoteric polysaccharide.

Claims (4)

1. A method for enhancing the detergent properties of enzymes of a detergent composition having at least one enzyme, comprising the step of adding to said composition an amphoteric polysaccharide, wherein the amphoteric polysaccharide has a DS anionic value greater than its DS cationic value, the DS anionic value is from 0.01 to 0.2, and the DS cationic value is from 0.001 to 0.1, and an enzyme having detergent properties wherein the enzyme is 1.0-5.0 wt. % of the detergent composition.

2. A composition comprising at least a detergent, an enzyme having detergent properties wherein the enzyme is 1.0-5.0 wt. % of the detergent composition, and an amphoteric polysaccharide, wherein the amphoteric polysaccharide has a DS anionic value greater than its DS cationic value, and the amphoteric polysaccharide has a DS cationic value of 0.001 to 0.1.

3. The method according to claim 1 wherein the enzyme is 1.0-1.5 wt. % of the detergent composition.

4. The composition according to claim 2 wherein the enzyme is 1.0-1.5 wt. % of the detergent composition.
