Patent ID: 8187580

Claim:
A non-encapsulated benefit agent delivery system suitable for delivering a benefit agent to a substrate, the benefit agent delivery system comprising an aqueous dispersion of from about 0.002% to about 0.05%, by weight, of a water-insoluble polymer particle and from about 0.001% to about 10%, by weight, of a benefit agent, wherein the polymer particle has a glass transition temperature from about 50° C. to about 120° C. and is a polymer of vinyl acetate and vinyl pyrrolidone at a weight ratio of vinyl acetate: vinyl pyrrolidone in the range of about 10:0.02 to about 5:2.5 and the polymer and the benefit agent are non-polymerically associated; and when the benefit agent delivery system is deposited onto the substrate, directly or indirectly, the Response Factor (RF) exhibited by the benefit agent delivery system is at least about 1.5, as measured by Test Protocol I or II, wherein said benefit agent is a member selected from the group consisting of top note perfume raw materials and perfume accords having a Kovats Index of from about 1000 to about 1400; said dispersion comprising a colloidal stabilizer; said dispersion having a viscosity in a range of between 7000-10000 cps.
