Abstract

Described herein are liquid cleansing compositions having a reduced slippery skin feel comprising a) surfactants comprising (i) an alkali metal or ammonium alkyl ether sulfate, (ii) a betaine surfactant and (iii) a fatty acid amide; and b) polyethylene glycol.

First claim

What is claimed is:

1. An aqueous cleansing composition, comprising:
a surfactant combination consisting of sodium lauryl ether sulfate, cocamidopropyl betaine, and cocomonoethanol amide;
a fatty acid soap present in an amount of 0.1 wt % to 1 wt % based on a total weight of the composition on an active basis; and
polyethylene glycol, wherein the polyethylene glycol is present in an amount of 0.5 wt. % to 1.2 wt. % by total weight of the composition,
wherein the surfactant combination is present in a total amount of 5 wt % to 15 wt % based on a total weight of the composition on an active basis,
wherein the sodium lauryl ether sulfate is present in an amount of 5 wt. % to 9 wt. % based on a total weight of the composition on an active basis,
wherein the cocamidopropyl betaine is present in an amount of 0.5 wt. % to 3.5 wt. % based on a total weight of the composition on an active basis,
wherein the cocomonoethanol amide is present in an amount of 0.05 wt. % to 2 wt. % based on a total weight of the composition on an active basis, and
wherein the polyethylene glycol has a molecular weight of from about 400 Da to about 3200 Da.

2. The composition according to claim 1 , further comprising a foaming agent, the foaming agent comprising lauramidopropylamine oxide.

3. The composition of claim 1 , wherein the composition is in the form of a body wash, shower gel or a liquid soap.

4. A method comprising applying the composition of claim 1 to skin, cleansing the skin, and optionally, rinsing the skin.

5. The composition according to claim 1 , wherein the polyethylene glycol has a molecular weight of about 600 Da.

6. The composition according to claim 5 , further comprising soap chips, wherein the soap chips comprise the fatty acid soap.

7. The composition according to claim 1 , wherein the polyethylene glycol has a molecular weight of from about 600 Da to about 1450 Da.

8. The composition of claim 2 , wherein the lauramidopropylamine oxide is present in an amount of 0.3 wt % to 1 wt % based on a total weight of the composition on an active basis.

9. The composition of claim 2 , wherein the lauramidopropylamine oxide is present in an amount of 0.4 wt % to 1 wt % based on a total weight of the composition on an active basis.

10. The composition of claim 2 , wherein the lauramidopropylamine oxide is present in an amount of 0.5 wt % to 1 wt % based on a total weight of the composition on an active basis.

11. The composition of claim 2 , wherein the lauramidopropylamine oxide is present in an amount of 0.5 wt % based on a total weight of the composition on an active basis.

12. The composition of claim 1 , wherein the molecular weight of the polyethylene glycol is about 1,450 Da.

13. The composition of claim 1 , wherein the surfactant combination is present in a total amount of 8 wt % to 10 wt % based on a total weight of the composition on an active basis.
