US 10,870,816 B2 · Fabric treatment compositions having low calculated cationic charge density polymers and fabric softening actives and methods for providing a benefit

Abstract

A fabric treatment composition having a polymer and a fabric softening active. The polymer includes a cationic repeating unit and a non-cationic repeating unit. The polymer has a weight-average molecular weight of from about 40,000 to about 600,000 Daltons. The polymer has a calculated cationic charge density of from about 0.05 to about 2 meq/g at a pH of between about 2 and about 8. The polymer includes less than about 0.1% by mole of a cross-linking agent. The fabric softening active includes a quaternary ammonium compound. The composition has less than about 5% by weight of the composition of an anionic surfactant.
