Fabric care composition with delivery particles

A fabric care composition comprising:

• quaternary ammonium ester material,
• wherein the quaternary ammonium ester material comprises triester quaternary ammonium material (“triester quats”),
• wherein the triester quaternary ammonium material is derived, in part, from C13-C22 fatty acids;
• and
• a population of delivery particles,
• wherein the delivery particles comprise a core and shell surrounding the core,
• wherein the core comprises a benefit agent,
• wherein the shell comprises a polymeric material that is the reaction product of a polyisocyanate and hydrolyzed chitosan,
• wherein the shell comprises the hydrolyzed chitosan at a level of at least 21 wt %, by weight of the shell;
• and
• wherein the hydrolyzed chitosan is characterized by one or more of the following:
• a) a degree of deacetylization of at least 85%, and
• b) a weight average molecular weight of 95 kDa or less.
