Abstract
The invention provides a composition comprising a benefit agent delivery particle comprising dextran as a delivery aid. The benefit agent delivery particle may further comprise a non-polysaccharide polymer, preferably an aminoplast polymer. The benefit agent delivery particle may comprise a perfume. The invention also provides a process for the manufacture of the particles in which perfume oil is encapsulated using emulsion polymerization to form core-shell particles, (in the alternative the perfume may be adsorbed later) and, a further polymer layer is formed on the outer surface of the core shell-particles in the presence of the delivery aid.
Claims10
A benefit agent delivery particle having at the outer surface of the particle one or more delivery aids which include dextran.
A particle according to claim 1 or 2 wherein the dextran has a molecular weight above 5 kD, preferably above 20 kD.
A particle according to any preceding claim which further comprises a non-polysaccharide polymer, preferably an aminoplast polymer.
A particle according to any preceding claim which comprises a perfume.
A particle according to any preceding claim which comprises a core and a shell.
