Abstract

The invention provides a personal care composition, preferably for use on human skin and/or hair, including a core-shell benefit agent carrier particle comprising: a) a core, optionally comprising a benefit agent; b) at least one polymer shell surrounding the core, c) a deposition aid, attached to the outer shell and not removed by exposure to water, said deposition aid comprising at least one polysaccharide selected from the group consisting of poly-mannan, poly-glucan, poly-glucomannan, poly-xyloglucan, poly-galactomannan, dextran, hydroxyl-propyl cellulose, hydroxy-propyl methyl cellulose, hydroxy-ethyl methyl cellulose, hydroxy- propyl guar, hydroxy-ethyl ethyl cellulose or methyl cellulose, with the proviso that the particle is not a particle having an average diameter of less than 50 micron comprising; i) at least one shell formed by a step-growth polymerisation reaction, ii) interior to said shell, at least one region formed by chain-growth polymerisation reaction which does not involve an isocyanate, wherein the shell is polymerised prior to the core.
