1. A fabric care composition comprising:
water;
a cleaning surfactant;
a fabric softening silicone; and
a deposition aid polymer, wherein the deposition aid polymer is a dextran polymer functionalized with quaternary ammonium moieties; wherein the deposition aid polymer is a branched chain dextran polymer functionalized with quaternary ammonium groups; wherein the branched chain dextran polymer comprises a plurality of glucose structural units; wherein 90 to 98 mol % of the glucose structural units are connected by α-D-1,6 linkages; 2 to 10 mol % of the glucose structural units are connected by α-1,3 linkages and wherein less than 0.1 mol % of the linkages between individual glucose units in the deposition aid polymer are β-1,3 linkages; and
wherein the deposition aid polymer enhances deposition of the fabric softening silicone from the fabric care composition onto a fabric.
