A core comprising an optional benefit agent; an inner shell at least partially surrounding the core, the first polymer having a glass transition temperature of 70 degrees Celsius or higher, preferably 80 degrees Celsius or higher An inner shell that is a water-insoluble product of a polymerization reaction to form; and an outer shell that at least partially surrounds the inner shell, having a glass transition temperature of 35 degrees Celsius or less. Particles comprising the outer shell which is a water-insoluble product of a polymerization reaction to form a polymer; and a deposition aid covalently bonded to the outer shell. |
