摘要：
The invention provides a composition comprising a benefit agent delivery particle comprising at least one of hydroxylpropyl methyl cellulose, hydroxylethyl methyl cellulose, hydroxylpropyl guar, hydroxylethyl ethyl cellulose or methyl 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.
