Abstract
Detergent compositions are provided that include a polysaccharide selected from a carboxymethyl cellulose component, an anionic cellulose derivative, or mixtures thereof and a surfactant system, wherein the polysaccharide has a molecular weight of no greater than from about 1,000 Dalton to 80,000 Dalton.
Claims21
A detergent composition comprising a polysaccharide and from about 5% to about 70% by weight of a surfactant system, based on a total weight of the composition;
- wherein the polysaccharide is selected from the group consisting of a carboxymethyl cellulose component, an anionic cellulose derivative, and mixtures thereof;
- wherein the polysaccharide has a weight average molecular weight in a range of from about 1,000 Dalton to 40,000 Dalton;
- and wherein the detergent composition does not contain any polysaccharide having a molecular weight peak greater than about 80,000 Dalton.
A laundry detergent composition comprising a carboxymethyl cellulose component at a concentration from about 0.005% to about 10% by weight of the detergent composition and a surfactant system at a concentration from about 5% to about 70% by weight of the detergent composition;
- wherein the carboxymethyl cellulose component has a weight average molecular weight in a range of from about 1,000 Da to 40,000 Da, the laundry detergent does not comprise any polysaccharide having a molecular weight peak greater than about 80,000 Da, and the laundry detergent composition is in a liquid form.
A detergent composition comprising a polysaccharide and from about 5% to about 70% by weight of a surfactant system, based on a total weight of the composition;
- wherein the polysaccharide is selected from the group consisting of a carboxymethyl cellulose component, an anionic cellulose derivative, and mixtures thereof;
- wherein the polysaccharide has a weight average molecular weight in a range of from about 1,000 Dalton to 40,000 Dalton;
- wherein the detergent composition does not comprise any polysaccharide having a molecular weight peak greater than about 80,000 Dalton;
- and wherein the detergent composition does not comprise a bacterial cellulose.
A method of cleaning an article selected from clothes or dishes, said method comprising washing the article in the presence of a detergent composition, said detergent composition comprising a polysaccharide and from about 5% to about 70% by weight of a surfactant system, based on a total weight of the composition;
- wherein the polysaccharide is selected from the group consisting of a carboxymethyl cellulose component, an anionic cellulose derivative, and mixtures thereof;
- wherein the polysaccharide has a weight average molecular weight in a range of from about 1,000 Dalton to 40,000 Dalton;
- and wherein the detergent composition does not contain any polysaccharide having a molecular weight peak greater than about 80,000 Dalton.
