摘要： A laundry care or dish care composition including a poly alpha glucan derivative, wherein the poly alpha glucan derivative includes: (i) a poly alpha glucan backbone of glucose monomer units, wherein greater than or equal to 40% of the glucose monomer units are linked via alpha-1,3 glycosidic linkages, or a combination of alpha-1,3 and alpha-1,6 glycosidic linkages, and optionally at least 5% of the backbone glucose monomer units have branches via alpha-1,2 glycosidic linkages; and
(ii) at least one organic group linked to the poly alpha glucan backbone through a linkage moiety; wherein, the poly alpha glucan backbone has a weight average degree of polymerization of from 51 to 150; and wherein, the poly alpha glucan derivative has a degree of substitution of linkage moiety of from 0.001 to 3.00.

摘要： 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 40% of the glucose monomer units are linked via alpha-1,6 glycosidic linkages, and wherein from 0% to less than 30% of the glucose monomer units are linked via alpha-1,3 glycosidic linkages, and optionally at least 5% of the backbone glucose monomer units have branches via alpha-1,2 and/or alpha-1,3 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 5; and

wherein, the poly alpha-1,6-glucan derivative has a degree of substitution of





linkage moiety of from 0.20 to 1.00.
