## Abstract

The disclosure relates to compositions comprising a poly alpha-1,3-glucan derivative. The poly alpha-1,3-glucan derivative is a poly alpha-1,3-glucan polymer wherein the polymer is substituted with at least one polyether group and/or polyamine group. Compositions comprising the poly alpha-1,3-glucan derivative are useful as detergent compositions.
