IMPROVEMENTS RELATING TO FABRIC TREATMENT COMPOSITIONS COMPRISING TARGETED BENEFIT AGENTS

摘要

The invention provides a composition comprising a benefit agent delivery particle comprising hydroxy-propyl cellulose (HPC), preferably with a molecular weight above 5OkD, as a delivery aid. Preferably the molar substitution of the HPC is in the range from 2.8 to 4.0. The benefit agent delivery particle may comprise a 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, and, a further polymer layer is formed on the outer surface of the core shell-particles in the presence of the HPC. Preferably the latter step is done a temperature below the cloud point of the HPC.
