Fabric care composition

A fabric care composition comprising:

• a fabric care benefit agent;
• and
• 1 to 5 wt %, based on weight of the fabric care composition, of a deposition aid polymer, comprising:
• (a) 82 to 96 wt %, based on weight of the deposition aid polymer, of structural units of formula (I)
• wherein each R1 is independently selected from the group consisting of a hydrogen and a methyl group;
• and
• (b) 4 to 18 wt %, based on weight of the deposition aid polymer, of structural units of formula (II)
• wherein each R2 is independently selected from the group consisting of a moiety of Formula (III), a moiety of Formula (IV) and a moiety of Formula (V)
• wherein A− is a counter anion balancing the cationic charge on the N;
• wherein each R4 is independently selected from the group consisting of a hydrogen and a C1-2 alkyl group;
• and wherein each R5 is a hydrogen;
• wherein the deposition aid polymer has a weight average molecular weight of <100,000 Daltons;
• and with the proviso that the deposition aid polymer has an average of 3 to 20 structural units of formula (II) per molecule.
