  • Patent number: 11905495
    Abstract: Treatment compositions, such as fabric care or dish care compositions, that include poly alpha-1,6-glucan ether compounds, which include poly alpha-1,6-glucans substituted with at least one positively charged organic group, the compounds being characterized by, for example, a degree of substitution of about 0.001 to about 3.0, and optionally, where about 3% or more of the backbone glucose monomer units have branches via alpha-1,2- and/or alpha-1,3-glycosidic linkages. Methods related to making and using such compositions.

  • Publication number: 20230287148
    Abstract: The disclosure relates to poly alpha-1,6-glucan ester compounds comprising poly alpha-1,6-glucan substituted with at least one ester group as defined herein and having a degree of substitution of about 0.001 to about 3.0. The poly alpha-1,6-glucan comprises a 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 optionally at least 5% of the backbone glucose monomer units have branches via alpha-1,2 and/or alpha-1,3 glycosidic linkages. Compositions comprising a poly alpha-1,6-glucan ester compound can be useful in various applications.

  • Publication number: 20210388290
    Abstract: A laundry care or dish care composition can include a poly alpha-1,6-glucan ester compound, where the poly alpha-1,6-glucan ester compound includes: (i) a poly alpha-1,6-glucan backbone wherein 40% or more of the glucose monomer units are linked via alpha-1,6-glycosidic linkages; and from 0 to 50% glucose units of the poly alpha-1,6 glucan backbone further contains glucose branching moiety linked via alpha-1,2- or alpha-1,3-glycosidic linkages; and (ii) one or more ester groups selected from: (a) an aryl ester group; (b) a first acyl group comprising —CO—R?, wherein R? comprises a chain of 1 to 24 carbon atoms, and (c) a second acyl group comprising —CO—Cx-COOH, wherein the -Cx- portion of the second acyl group comprises a chain of 2 to 24 carbon atoms, wherein the poly alpha-1,6-glucan ester compound has a degree of polymerization (DPn) in the range of 5 to 1400, and wherein the degree of substitution of ester groups is from about 0.001 to about 1.50.
