Abstract

A water-dispersible particle wherein the material comprises (i) one or more polymeric deposition materials having an average repeat unit (I): 1 wherein at least one or more R groups of the polymer are independently selected from H, a hydrolysable group or a linker group in which when R is a hydrolysable group the degree of substitution is 0 to 3 and when R is a linker group the degree of substitution is 0.01 to 3; (ii) a benefit agent attached to the deposition enhancing part; characterised in that the water-dispersible particle has a particle size from 20 to 5,000 nm.
