Abstract

An aqueous personal care composition comprising: one or more amphoacetates; one or more glutamate surfactants selected from sodium lauroyl glutamate, dipotassium cocoyl glutamate, potassium lauryl/myristoyl glutamate and combinations thereof; and cocamide MIPA; wherein the composition is free of sulfates and ethoxylates.

Claims (26)

1. An aqueous personal care composition comprising:

a. one or more amphoacetates;

b. one or more glutamate surfactants selected from the group consisting of sodium lauroyl glutamate, dipotassium cocoyl glutamate, potassium lauroyl/myristoyl glutamate and combinations thereof; and

c. cocamide MIPA;

wherein the composition is free of sulfates and contains less than 0.5 wt % of alcohol ethoxylates, alkyl phenol ethoxylates and ethyl phenyl ethoxylate containing compounds, wherein the composition has a viscosity of 7,000-15,000 cps measured using a Brookfield Viscometer Model DV-II+ at 10 rpm with a TV spindle 4.

2. The composition of claim 1 , wherein the pH ranges from 5 to 6.

3. The composition of claim 1 , wherein the amphoacetate is sodium lauroamphoacetate.

4. The composition of claim 3 , wherein the sodium lauroamphoacetate is present in an amount of about 8 to about 12 weight percent based upon the total weight of the composition.

5. The composition of claim 1 , wherein the dipotassium cocoyl glutamate is present in an amount of about 3 to about 5 weight percent based upon the total weight of the composition.

6. The composition of claim 1 , wherein the cocamide MIPA is present in an amount of about 1 to about 3 weight percent based upon the total weight of the composition.

7. The composition of claim 1 , wherein the composition is a body wash.

8. The composition of claim 1 , wherein the composition is a baby wash comprising sodium lauroyl glutamate, sodium lauroamphoacetate, cocamide MIPA, and PEG-80 sorbitan laurate.

9. The composition of claim 8 , wherein the pH ranges from 5 to 6.

10. The composition of claim 8 , wherein the sodium lauroamphoacetate is present in an amount of about 8 to about 12 weight percent based upon the total weight of the composition.

11. The composition of claim 8 , wherein the dipotassium cocoyl glutamate is present in an amount of about 3 to about 5 weight percent based upon the total weight of the composition.

12. The composition of claim 8 , wherein the cocamide MIPA is present in an amount of about 1 to about 3 weight percent based upon the total weight of the composition.

13. An aqueous personal care composition comprising:

potassium lauroyl/myristoyl glutamate,

sodium cocoamphoacetate, and

cocamide MIPA,

sodium methyl oleoyl taurate,

wherein the composition is free of sulfates and contains less than 0.5 wt. % of alcohol ethoxylates, alkyl phenol ethoxylates and ethyl phenyl ethoxylate containing compounds, wherein the composition has a viscosity of 7,000-15,000 cps measured using a Brookfield Viscometer Model DV-II+ at 10 rpm with a TV spindle 4.

14. The composition of claim 3 , wherein the glutamate surfactant is potassium lauroyl/myristoyl glutamate.

15. The composition of claim 2 , wherein the amphoacetate is sodium lauroamphoacetate and the glutamate surfactant is sodium lauroyl glutamate.

16. The composition of claim 2 , wherein the amphoacetate is sodium lauroamphoacetate and the glutamate surfactant is dipotassium cocoyl glutamate.

17. The composition of claim 2 , wherein the amphoacetate is sodium lauroamphoacetate and the glutamate surfactant is potassium lauroyl/myristoyl glutamate.
