Benefit agent delivery particles comprising dextran

摘要

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.

主权项

1. A benefit agent delivery particle comprising:
at least one delivery aid and an aminoplast polymer; wherein the at least one delivery aid comprises dextran; wherein the dextran is located at the outer surface of the particle; and wherein the dextran is an α-D-1,6-glucose-linked glucan with 1-3-branch linkages.
