Abstract

A laundry care or dish care composition can include a poly alpha-1,6-glucan derivative, wherein the poly alpha-1,6-glucan derivative includes:
(i) a poly alpha-1,6-glucan backbone of glucose monomer units, wherein greater than or equal to 80% of the glucose monomer units are linked via alpha-1,6 glycosidic linkages, and wherein from about 10% or less of the glucose monomer units are linked via alpha-1,3 glycosidic linkages, 1,2 glycosidic linkages, and/or 1,4 glycosidic linkages; and (ii) at least one organic group linked to the poly alpha-1,6-glucan backbone through a

 linkage moiety;
wherein, the poly alpha-1,6-glucan backbone has a weight average degree of polymerization of at least about 5;
wherein, the poly alpha-1,6-glucan derivative has a degree of substitution of

 linkage moiety of from about 0.20 to about 1.00.

First claim

What is claimed is:

(i) a poly alpha-1,6-glucan backbone of glucose monomer units, wherein greater than or equal to 80% of the glucose monomer units are linked via alpha-1,6 glycosidic linkages, and wherein from about 10% or less of the glucose monomer units are linked via alpha-1,3 glycosidic linkages, alpha-1,2 glycosidic linkages, and/or alpha-1,4 glycosidic linkages; and (ii) at least one organic group linked to the poly alpha-1,6-glucan backbone through a

 linkage moiety;
wherein, the poly alpha-1,6-glucan backbone has a weight average degree of polymerization of at least about 5;
wherein, the poly alpha-1,6-glucan derivative has a degree of substitution of

linkage moiety of from about 0.20 to about 1.00 and wherein the poly alpha-1,6-glucan derivative is free from hydrophilic substitution comprising carboxylic acid, carboxylic acid salt, sulfonic acid derivative, sulfonic acid derivative salt, sulfuric acid derivative, sulfuric acid derivative salt, thiosulfate, thiosulfate salt, phosphoric acid derivative, phosphoric acid derivative salt, alkyl amine, alkyl substituted ammonium salt, quaternized pyridine salt, and quaternized imidazole salt.

2 . The laundry care or dish care composition according to claim 1 , wherein the organic group linked to the poly alpha-1,6-glucan backbone is a hydrophobic organic group.

3 .
