Abstract

Shampoo compositions comprising at least one surfactant; a silicone oil having an internal phase viscosity of less than about 50,000 cst, wherein said silicone oil is present as a preformed microemulsion of particles having an average particle size of less than about 0.15 microns, a cationic deposition polymer; an aqueous carrier and optionally a stabilizing agent provide a substantially clear shampoo composition, which provides superior conditioning to hair and/or skin while also providing excellent storage stability and high optical transparency or translucency.

Claims

1. A shampoo composition consisting of:

(a) from about 2% to about 35% by weight of at least one surfactant;

wherein the surfactant is selected from the group consisting of anionic, cationic, amphoteric, or nonionic surfactants, or mixtures thereof,

(b) from about 0.01% to about 10% by weight of a silicone oil having an internal phase viscosity of from about 5 csk about 50,000 csk, wherein said silicone oil is present as a preformed microemulsion of particles having an average particle size of less than about 0.15 microns, the emulsion comprising;

(i) water,

(ii) surfactants selected from the group consisting of TEA dodecyl benzene sulfonates, laureth 23 and combinations thereof and

(iii) the silicone oil;

 

wherein the molar equivalent of surfactant in the shampoo composition is equal to or greater than the molar equivalent of surfactant in the preformed microemulsion;

(c) from about 0.01% to about 10% by weight of a cationic deposition polymer selected from the group consisting of cationic cellulose polymers having a molecular weight of at least about 800,000 and cationic guar polymers having a molecular weight of at least about 800,000 and a charge density of at least about 0.1 meq/g;

(d) an aqueous carrier; and

(e) from about 0.1% to about 0.5% of a stabilizing agent.

2. A shampoo composition according to claim 1 wherein the particles of silicone oil have a particle size of less than about 0.1 microns.

3. A shampoo composition according to claim 1 wherein the silicone oil is present in the shampoo composition in an amount of from about 0.1 to about 5% by weight.

4. A shampoo composition according to claim 1 wherein the cationic deposition polymer is a cationic cellulose polymer.

5. A shampoo composition according to claim 1 wherein the cationic deposition polymer is Polyquaterium 10.

6. A shampoo composition according to claim 1 wherein the cationic deposition polymer is a cationic guar polymer.

7. A shampoo composition according to claim 6 wherein the cationic guar polymer is guar hydroxypropyl trimonium chloride.

8. A shampoo composition according to claim 1 wherein the stabilizing agent is a polymeric water soluble thickener.

9. A shampoo composition according to claim 1 wherein the stabilizing agent is a nonionic surfactant in addition to any surfactant already present in the preformed emulsion, wherein the nonionic surfactant is having an HLB range of from about 9 to about 18.
