  • TREATMENT COMPOSITIONS COMPRISING CATIONIC POLY ALPHA-1,6-GLUCAN ETHERS
    Publication number: 20240191156
    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.
