1. A laundry care or dish care composition comprising a poly alpha-1,6-glucan derivative, wherein the poly alpha-1,6-glucan derivative comprises:
(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 about 10% or less of the glucose monomer units are linked via alpha-1,3 glycosidic linkages, and optionally at least about 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-1,6-glucan backbone through a

OG Complex Work Unit Chemistry
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

OG Complex Work Unit Chemistry
linkage moiety of from about 0.001 to about 3.00, and wherein the poly alpha-1,6-glucan derivative is free from hydrophilic substitution.
