Abstract
A perfume encapsulate comprises an aminoplast capsule, the capsule shell comprising urea-formaldehyde or melamine-formaldehyde polymer and a second polymer comprising a polymer or copolymer of one or more anhydrides, preferably ethylene/maleic anhydride copolymer. The second polymer improves the stability of the capsules with respect to surfactant, thus improving perfume retention properties and enabling use of the capsules in aqueous surfactant-containing products in a way that has not hitherto been possible.
