Aerosol antidandruff composition
The present invention is directed to a foaming composition comprising: from about 18% to about 36% of one or more anionic surfactants; from 0 0.1 to about 5% of one or more viscosity modifiers with a molecular weight of from about 38 to about 2800; from about 0.1 to about 10% of an anti-dandruff particulate; from about 1% to about 10% of a blowing agent, and wherein the foam density is from about 0.05 to about 0.25 g/ml.
1. A foaming composition comprising:
i. From about 18% to about 36% of one or more anionic surfactants wherein the anionic surfactants comprise sodium laureth sulfate and sodium lauryl sulfate;
ii From 0.1 to about 5% of one or more viscosity modifiers with a molecular weight of from about 75 to about 350, wherein the viscosity modifiers comprise sodium chloride and sodium xylene sulfonate;
iii. From about 4% to about 10% of an anti-dandruff particulate wherein the anti-dandruff particulate is zinc pyrithione;
iv. From about 1% to about 10% of a blowing agent, wherein the blowing agent comprises one or more volatile materials, which in a gaseous state, carry the other components of the foaming composition in particulate or droplet form wherein the blowing agent is selected from the group comprising isobutane, propane, and 1,3,3,3-Tetrafluoropropene,
v. From about 0.1% to about 5% of basic zinc carbonate;
(vi) From 0.1% to 5% of a stabilizing agent selected from the group consisting of trihydroxystearin, ethylene glycol distearatepolymers, and mixtures thereof;
(vii) a co-surfactant selected from the group consisting of lauramidopropyl betaine, cocoamidopropyl betaine, lauryl hydroxysultaine, sodium lauroamphoacetate, coco monoethanolamide, and mixtures thereof;
(viii) a cationic polymer wherein the cationic polymer is guar hydroxypropyltrimonium chloride;
(ix) a conditioning agent wherein the conditioning agent is a silicone; and
wherein the foam density is from about 0.05 to about 0.25g/ml and wherein the anti-dandruff deposition is equal to or greater than 0.8 microgram per cm 2 when compared to a liquid form control shampoo product comprising 1% zinc pyrithione and 1.61% zinc carbonate and having no blowing agent.
2. A foaming composition according to claim 1 wherein the viscosity (measured at 25 C) is less than 9000 cps.
3. A foaming composition according to claim 1 wherein the blowing agent is from about 2% to about 8%.
