1. A fabric care composition comprising:
50 to 75 wt %, based on weight of the fabric care composition, of water;
15 to 30 wt %, based on weight of the fabric care composition, of a cleaning surfactant;
0.1 to 5 wt %, based on weight of the fabric care composition, of a fabric softening silicone; and
0.5 to 5 wt %, based on weight of the fabric care composition, of 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 %; and
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)

OG Complex Work Unit Chemistry
and dimethyl(alkyl) ammonium moieties having formula (II)

OG Complex Work Unit Chemistry
wherein each R is independently selected from a C8-22 alkyl group; wherein the mol % substitution ratio of trimethyl ammonium moieties of formula (I) to dimethyl(alkyl) ammonium moieties of formula (II) is 3 to 10; and
wherein a weight ratio of the modified carbohydrate polymer to the cleaning surfactant in the fabric care composition is 1:5 to 1:40.
