A particle comprising: a core, comprising an optional benefit agent; an inner shell at least partially surrounding the core, said inner shell being the water insoluble product of a polymerisation reaction to form a first polymer with a glass transition temperature above and including 70 degrees Celsius, preferably above and including 80 degrees Celsius; an outer shell at least partially surrounding said inner shell, said outer shell being the water insoluble product of a polymerisation reaction to form a second polymer with a glass transition temperature below and including 35 degrees Celsius; and a deposition aid, covalently attached to the outer shell. |
