Abstract

A fabric care composition is provided including water; a cleaning surfactant; a fabric softening silicone; and a modified carbohydrate polymer having a weight average molecular weight of <500,000 Daltons and a Kjeldahl nitrogen content corrected for ash and volatiles, TKN, of ≥0.5 wt %; wherein the modified carbohydrate polymer is a carbohydrate polymer functionalized with quaternary ammonium moieties; wherein the quaternary ammonium moieties on the modified carbohydrate polymer include: trimethyl ammonium moieties having formula (I) and dimethyl(alkyl) ammonium moieties having formula (II) wherein each R is independently selected from a C8-22 alkyl group.
