## Abstract

A skin cleansing composition comprising a salt of lauric acid; a salt of stearic acid; and at least one surfactant that is not a salt of a fatty acid; wherein the ratio of the salt of lauric acid to the salt of stearic acid, calculated as the ratio of lauric acid to stearic acid by weight, is from 2.5:1 to 3.5:1. Also provided are methods of using the compositions.

## Claims

### Claim at position 1

1-26. (canceled)

### Claim 27

A liquid skin cleanser composition comprising:
a salt of lauric acid;
a blend of salts of stearic acid and palmitic acid;
at least one surfactant that is not a salt of a fatty acid; and
cocomonoethanolamide;
wherein the ratio of the salt of lauric acid to the blend of salts of stearic acid and palmitic acid, calculated as the ratio by weight of lauric acid to combined weight of stearic acid and palmitic acid, is from 2.5:1 to 3.5:1;
wherein the salt of lauric acid is potassium laurate; the blend of salts of stearic acid and palmitic acid is a blend of potassium stearate and potassium palmitate; the at least one surfactant that is not a salt of a fatty acid includes sodium laureth sulfate, cocoamidopropyl betaine, and ethoxylated fatty alcohol.

### Claim 28 (depends on 27)

The composition of claim 27, wherein the ratio of the salt of lauric acid to the combined salts of palmitic and stearic acids, calculated as the ratio of weight of lauric acid to combined weight of palmitic and stearic acid, is about 3:1.

### Claim 29 (depends on 27)

The composition of claim 27, wherein the ratio of the amount of salt of palmitic acid to the amount of salt of stearic acid in the blend, calculated as the ratio of weight of palmitic acid to stearic acid in the blend is from 1.3:1 to 1.8:1; preferably about 1.5:1.

### Claim 30 (depends on 27)
