Abstract
The invention provides a benefit agent delivery particle comprising hydroxylpropyl cellulose. 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.
