Abstract

The present invention relates to personal care cleansing compositions prising specific surfactant systems used in combination with high levels of glycerin.

First claim

The invention claimed is:

1. A composition comprising:
1) 55 to 90% by wt. glycerin;
2) a surfactant system comprising:
a) 3 to 12% by wt. of the total composition of a surfactant selected from the group consisting of salts of N-acyl derivatives of dicarboxylic amino acids, salts of N-acyl derivatives of monocarboxylic acids, salts of N-acyl derivatives of taurine, and mixtures thereof
b) 1 to 15% by wt. of the total composition of a co-surfactant comprising a betaine and less than 50% by wt. of the surfactant system comprises the betaine; and

3) 5 to 55% by wt. of the total composition of water.

2. The composition according to claim 1 , wherein 50 to 90% by wt. of the surfactant system is the 2(a) surfactant.

3. The composition according to claim 1 , wherein 60 to 80% by wt. of the composition comprises the glycerin.

4. The composition according to claim 1 , wherein less than 40% of the surfactant system comprises the betaine.

5. The composition according to claim 1 , wherein the betaine is alkyl amido betaine.

6. The composition according to claim 5 , wherein less than 30% by wt. of the surfactant system comprises the alkyl amido betaine.

7. A method of enhancing glycerin deposition, the method comprising applying the composition of claim 1 to hair or skin.

8. The composition of claim 1 , wherein the 2(a) surfactant comprises a salt of N-acyl glutamate.

9. The composition of claim 8 , wherein the salt of N-acyl glutamate comprises sodium N-cocoyl-L glutamate, sodium N-lauroyl-L-glutamate, sodium N-myristoyl-L-glutamate, potassium N-cocoyl-I-glutamate, potassium N-lauroyl-L-glutamate, potassium N-myristoyl-Lglutamate, or a combination of two or more thereof.

10. The composition of claim 1 , wherein the 2(a) surfactant comprises a salt of N-acyl taurate.

11. The composition of claim 1 , wherein the betaine comprises cocoamidopropyl betaine.

12. The composition of claim 1 , wherein the betaine comprises cocoamidopropyl betaine.

13. A composition comprising:
1) 60 to 80% by wt. glycerin;
2) a surfactant system comprising:
a) 3 to 12% by wt. of the total composition of a surfactant selected from the group consisting of salts of N-acyl derivatives of dicarboxylic amino acids, salts of Nacyl derivatives of monocarboxylic acids, salts of N-acyl derivatives of taurine, and mixtures thereof;
b) 1 to 10% by wt. of the total composition of a co-surfactant comprising cocoamidopropyl betaine; wherein 60 to 90% by wt. of the surfactant system comprises the 2(a) surfactant and less than 40% by wt. of the surfactant system comprises the cocoamidopropyl betaine; and

3) 5 to 55% by wt. of the total composition of water.

14. The composition according to claim 13 , wherein less than 30% by wt. of the surfactant system comprises the cocoamidopropyl betaine.

15. The composition according to claim 13 , wherein the 2(a) surfactant comprises a salt of N-acyl glutamate.

16. The composition of claim 15 , wherein the salt of N-acyl glutamate comprises sodium N-lauroyl-L-glutamate.

17. The composition of claim 1 , wherein the composition has a conductance value of greater than 800 microseconds using a skin conductance test.

18. The composition of claim 1 , wherein the composition has a transepidermal water loss value of less than 35 g/(m 2 ·h).

19. The composition of claim 1 , wherein the composition has a deposition value of greater than 60 micrograms per square centimeter.

20. The composition of claim 13 , wherein the composition has a deposition value of greater than 60 micrograms per square centimeter.
