Abstract

A composition s provided comprising: a) polymeric particles comprising a copolymer of a hydrophobic monomer and a hydrophilic Polysaccharide; b) a pharmaceutical and/or skin and/or hair and/or laundry active residing within and/or on the surface of the polymeric particles; and c) a pharmaceutically and/or cosmetically acceptable vehicle within which the polymeric particles are dispersed. The composition shows improved target specificity for skin, hair and silk fibres, synthetic fibres (including nylon and polyester) for delivery of pharmaceutical and/or skin and/or hair and/or laundry actives.
