Abstract

The present invention relates to compositions which provide both a skin cleansing and skin moisturizing benefit from the same product. These compositions provide improved lathering and cleansing characteristics, are extremely mild to the skin, and deliver a moisturizing agent to the skin. These compositions comprise at least one anionic surfactant, a dispersed, insoluble oil phase, at least one additional surfactant, an optional suspending agent, and water. This invention also relates to methods for providing combined cleansing and moisturization, and to methods for delivering these compositions as a foam.

Claims

1. A personal cleansing and moisturizing composition comprising:

(a) from about 1% to about 10% of at least one anionic surfactant,

(b) from about 0.4% to about 15% of a long chain C16-22 suspending agent selected from the group consisting of ethylene glycol long chain esters, alkanolamides of long chain fatty acids, long chain esters of long chain fatty acids, glyceryl long chain esters, lone chain esters of long chain alkanolamides, and mixtures thereof,

(c) from about 0.1% to about 10% of a dispersed, insoluble, oil phase,

(d) from about 1% to about 10% of at least one additional surfactant selected from the group consisting of nonionic surfactants, zwitterionic surfactants, amphoteric surfactants, and mixtures thereof, and

(e) the remainder water.

2. A composition according to claim 1 comprising from about 5% to about 15% of a suspending agent wherein said anionic surfactant is selected from the group consisting of ethoxylated alkyl sulfates, alkanoyl sarcosinates, and mixtures thereof.

3. A composition according to claim 2 wherein said anionic surfactant is selected from sodium laureth-3 sulfate, sodium lauroyl sarcosinate, and mixtures thereof.

4. A composition according to claim 3 wherein said long chain acyl derivative is an ethylene glycol long chain ester or diester.

5. A composition according to claim 4 wherein said long chain acyl derivative is ethylene glycol distearate.

6. A composition according to claim 5 wherein said additional surfactants are selected from the group consisting of ethoxylated glyceryl esters, alkanoylamidopropyl betaines, alkanoylamido hydroxysultaines, and mixtures thereof.

7. A composition according to claim 6 wherein said additional surfactants are selected from the group consisting of PEG-80 glyceryl cocoate, cocamidopropylbetaine, cocamidopropyl hydroxysultaine, and mixtures thereof.

8. A composition according to claim 7 wherein said dispersed oil phase is selected from the group consisting of silicones, hydrocarbons, fatty acids, fatty acid derivatives, cholesterol, cholesterol derivatives, vegetable oils, vegetable oil derivatives, and mixtures thereof.

9. A composition according to claim 8 wherein said dispersed oil phase comprises petrolatum, a C_10-22 fatty acid ester, and mixtures thereof.

10. A composition according to claim 9 wherein said dispersed oil phase comprises petrolatum, cetyl ricinoleate, and mixtures thereof.

11. A composition according to claim 8 wherein said dispersed oil phase comprises a vegetable oil derivative.

12. A composition according to claim 11 wherein said vegetable oil derivative is maleated soybean oil.

13. A composition according to claim 8 wherein said dispersed oil phase comprises a non-volatile silicone.

14. A composition according to claim 13 wherein said non-volatile silicone is selected from the group consisting of dimethicone copolyol, dimethylpolysiloxane, diethylpolysiloxane, high molecular weight dimethicone, mixed C₁ -C₃₀ alkyl polysiloxane, phenyl dimethicone, dimethiconol, and mixtures thereof.

15. A composition according to claims 14 wherein said non-volatile silicone is selected from dimethicone, dimethiconol, mixed C₁ -C₃₀ alkyl polysiloxane, and mixtures thereof.

16. A cleansing composition according to claim 1 wherein said composition has a viscosity of from about 0.1 cPs to about 40 cPs (25°
