Abstract

Shampoos are disclosed which comprise a synthetic surfactant, an insoluble, non-volatile silicone, a suspending agent and water. Suitable suspending agents include long chain esters of ethylene glycol, esters of long chain fatty acids, long chain amine oxides among many others.

Claims

1. A shampoo composition comprising

(a) from about 5% to about 70% of a synthetic surfactant selected from the group consisting of anionic surfactants, zwitterionic surfactants, amphoteric surfactants and mixtures thereof;

(b) from about 0.01% to about 10% of a dispersed, insoluble, nonvolatile silicone;

(c) from about 0.5% to about 5% of a long chain (C₁₆ -C₂₂) acyl derivative or long chain (C₁₆ -C₂₂) amine oxide selected from the group consisting of ethylene glycol long chain esters, alkanol amides of long chain fatty acids, long chain esters of long chain fatty acids, glyceryl long chain esters, long chain esters of long chain alkanolamides, long chain alkyl dimethyl amine oxides and mixtures thereof; and

(d) the remainder water.

2. A shampoo composition according to claim 1 wherein the non-volatile silicone is selected from the group consisting of polydimethylsiloxanes having viscosities of from about 5 to about 100,000 centistokes at 25°

C., polypropylene oxide modified dimethylsiloxanes and silicone gums.

3. A shampoo composition according to claim 2 wherein the surfactant is selected from the group consisting of amphoteric surfactants, zwitterionic surfactants and mixtures thereof.

4. A shampoo composition according to claim 2 wherein the surfactant is anionic.

5. A shampoo composition according to claim 3 wherein the non-volatile silicone is selected from the group consisting of polydimethylsiloxanes having viscosities of from about 5 to about 100,000 centistokes at 25°

C. and polypropylene oxide modified dimethylsiloxanes.

6. A shampoo composition according to claim 5 which in addition contains from about 0.01% to about 10% of a quaternary ammonium compound.

7. A shampoo composition according to claim 6 wherein the surfactant is a betaine.

8. A shampoo composition according to claim 7 wherein the acyl derivative is ethylene glycol distearate.

9. A shampoo composition according to claim 8 wherein the shampoo composition has a pH of from about 2 to about 4.
