Abstract

An liquid cleansing composition is disclosed that contains a specific levels of polyol(s), monoalkyl sulfosuccinate surfactant(s), N-acyl amino acid(s) or salt(s) thereof, and optionally monoalkyl phosphate(s) that provides excellent user properties including fast rinsing, squeaky clean feel and excellent lather.

Claims

1. A cleansing composition comprising:

a. about 30 to 54% by wt. of total polyol(s);

b. about 5 to 10% by wt. of total normal C10 to C16 mono alkyl sulfosuccinate(s), and c. about 0.6 to 9% by wt. of N-acyl amino acid(s) or salt(s) of such acid(s) or a blend there of.

2. The composition of claim 1 further comprising at least about 2 to 5% by wt. of total normal C8 to C24 mono alkyl phosphate(s);

3. The composition of claim 1 further comprising at least about 15% by wt. of water.

4. The composition of claim 2 wherein the ratio of total mono alkyl sulfosuccinate(s) to total mono alkyl phosphate(s) is in the range of about 1:

10 to about 10;

1.

5. The composition of claim 1 wherein the ratio of total mono alkyl sulfosuccinate(s) to total N-acyl amino acid surfactant(s) is in the range of about 1:

10;

to about 10;

1.

6. The composition of claim 1 wherein the polyol(s) is/are selected from glycerin, diglycerin, ethoxylated glycerin, propoxylated glycerin, propylene glycol, dipropylene glycol, polypropylene glycol, polyethylene glycol, sorbitol, hydroxypropyl sorbitol hexylene glycol, 1,3-butylene glycol or 1,2,6-hexanetriol or blends thereof.

7. The composition of claim 1 wherein the monoalkyl sulfosuccinate(s) is/are selected from C10, C12 or C14 monoalkyl sulfosuccinate(s) or blends thereof.

8. The composition of claim 2 wherein the mono alkyl phosphate(s) can be in either the acid or neutralized form and where the alkyl group is in the range of C6 to C20.

9. The composition of claim 1 wherein the N-acyl amino acid surfactant(s) has/have alkyl chain length(s) in the range of C8 to C16.

10. The composition of claim 1 wherein the viscosity is in the range of about 5,000 to 1,000,000 cps at 25 C as measured via the T-bar method.

11. The composition of claim 1 further comprising about 0.1% to 15% by wt. of an ordered liquid crystalline phase inducing structurant inducing a liquid crystalline phase in said composition.

12. A composition according to claim 11 wherein the ordered liquid crystalline phase cleansing composition is a lamellar composition.

13. A composition according to claim 11 wherein the ordered liquid crystalline phase inducing structurant is selected from a C8 to C24 alkenyl or branched alkyl fatty acid or ester thereof, a C8 to C24 alkenyl or branched alkyl alcohol or ether thereof, a C5 to C14 linear alkyl fatty acid, trihydroxystearin, or derivatives or mixtures thereof.

14. A composition according to claim 13 wherein the ordered liquid crystalline phase inducing structurant is selected from lauric acid, oleic acid, palm kernel acid, palm fatty acid, coconut acid, isostearic acid, or derivatives or mixtures thereof.

15. A composition according to claim 1 further comprising cationic polymer(s) in a total concentration of greater than about 0.1% by wt.

16. The composition of claim 1 further comprising less than about 4% by wt. of total tri- and diglyceride oil(s).

17. The composition of claim 1 further comprising less than about 1% by wt. of dialkylene glycol(s).

18. The composition of claim 1 further comprising less than about 5% by wt. of soap(s).

19. A method for cleansing the skin or hair with a quick rinsing cleansing composition according to claim 1 having durable lather, comprising the steps of:

a. applying the durable lathering composition to the skin or hair;

d. rinsing the composition from the skin or hair; and

e. drying the skin or hair.
