Abstract
A laundry detergent composition includes: (i) detersive surfactant; and (ii) polyalpha-1,3-glucan compounds.
Claims12
A laundry detergent composition comprising:
- (i) detersive surfactant at 10 to 40 percent by weight of the laundry detergent composition;
- and
- (ii) polyalpha-1,3-glucan ester compound at 0.1 to 10 percent by weight of the laundry detergent composition, the polyalpha-1,3-glucan ester compound comprising poly alpha-1,3 glucan backbone and ester group modification,
- wherein the poly alpha-1,3 glucan backbone:
- has less than about 10% branching point, and
- contains about 6 or more glucose units,
- wherein the ester group modification being one or more independently selected from:
- (a) an acetyl;
- (b) an aryl ester group;
- (c) an acyl group
- wherein a is independently about 6-24;
- and
- (d) an acyl group
- wherein R3 can be independently selected from H atoms, linear alkyl groups, branched alkyl groups, cyclic alkyl groups, and aryl groups comprising from one to 24 carbon atoms, and wherein (d) is different from (a) and (c);
- (e) an acyl group comprising —CO—Cx—COOR3, wherein the —Cx— portion of the second acyl group comprises a chain of about 2 to about 24 carbon atoms, and R3 comprises a chain of about 1 to about 24 carbon,
- with the proviso that (a) is present, and at least one other ester group (b), (c) (d) and/or (e) are present, and
- wherein the degree of substitution of the ester group modification is from about 0.001 to about 3.
