Abstract

Methods of cleansing skin comprise the steps of contacting the skin with a cleansing compositions comprising a fatty ester in combination with a lipid, and either rinsing the composition from the skin with water or wiping the composition from the skin with a dry or damp substrate. The cleansing compositions can comprise at least 8%, by weight of the composition, of fatty ester and/or further comprise a nonionic surfactant and less than about 50%, by weight of the composition, of an alcohol solvent such as ethanol, isopropanol, or mixtures thereof. The methods and compositions provide skin cleansing and hydration benefits.

Claims

1. A method of cleansing skin, said method comprising the steps of:

(a) contacting said skin with a composition comprising;

i) from about 8% to about 20%, by weight of the cleansing composition, of a fatty ester selected from the group consisting of isopropyl palmitate, isopropyl isostearate, and a mixture thereof;

ii) from about 1% to about 10%, by weight of the cleansing composition, of a high modulus lipid comprising petrolatum and mineral oil;

iii) a surfactant combination comprising from about 0.2% to about 2%, by weight of the cleansing composition, of a nonionic surfactant;

from about 0.5% to about 5%, by weight of the cleansing composition, of an anionic surfactant; and

from about 0.5% to about 5%, by weight of the cleansing composition;

of an amphoteric surfactant;

iv) a humectant; and

v) a hydrophobic structuring agent; and

(b) rinsing said skin with water or wiping said skin with a substrate.

2. The method of claim 1, wherein said hydrophobic structuring agent is selected from the group consisting of cetyl alcohol, stearyl alcohol, behenyl alcohol, and mixtures thereof.

3. The method of claim 2, wherein the nonionic surfactant comprises decyl polyglucoside.

4. The method of claim 3, wherein the amphoteric surfactant comprises cetyl betaine.

5. The method of claim 4, wherein the anionic surfactant comprises sodium lauryl sulfate.

6. The methof of claim 5, wherein the humectant comprises glycerin.

7. The method of claim 6, wherein said composition further comprises a cationic surfactant.

8. The method of claim 7, wherein said cationic surfactant is selected from the group consisting of distearyl dimethyl ammonium chloride, behenyl trimethyl ammonium chloride, stearamidopropyl dimethylamine, and mixtures thereof.
