Abstract
Benefit agent delivery systems, compositions incorporating such benefit agent delivery systems, and methods for making the delivery system in the compositions are provided. The benefit agent delivery systems of the present invention employ polymer particles having affinities for selected benefit agents, such as perfume, to form the polymeric assisted benefit agent delivery systems, which can effectively deposit benefit agents onto, onto the surface of a substrate, e.g., fabrics being laundered, hard surfaces, hair, skin or nails.
