Abstract

An aqueous cleansing composition comprising a cationic surfactant, a nonionic surfactant, and a thickener comprising an alkoxylated methyl glucose ether, wherein a weight ratio of cationic surfactant to nonionic surfactant is greater than 0.9:1. The combination of the cationionic:nonionic surfactant ratio with the alkoxylated methyl glucose ether thickener provides the composition with cold weather stability. Cold weather stability is observed when the composition remains transparent after cold storage.

First claim

What is claimed is:

1. An aqueous cleansing composition comprising:
a) from 1 to 5 weight % cetyltrimethylammonium chloride;
b) from 0.5 to 5 weight % of a nonionic surfactant mixture comprising laurylamidopropyl dimethyl amine oxide, myristylamidopropyl dimethyl amine oxide, and cocomonoethanolamide;
c) from 0.1 to 1.2 weight % sodium chloride; and
d) from 0.1 to 1 weight % of a thickener comprising PEG-120 methyl glucose dioleate;
wherein a weight ratio of the cationic surfactant to the nonionic surfactant is adapted to maintain transparency of the composition after 24 hour storage of the composition at 4.5° C.

2. The cleansing composition of claim 1 , further comprising a cationic antibacterial agent comprising at least one of a benzalkonium chloride, a benzethonium chloride, and mixtures thereof, wherein the cationic surfactant does not comprise the cationic antibacterial agent.

3. The cleansing composition of claim 1 , wherein the weight ratio of the cationic surfactant to the nonionic surfactant is greater than 0.9:1.

4. The cleansing composition of claim 1 , wherein the weight ratio of the cationic surfactant to the nonionic surfactant is at least 1:1.

5. The cleaning composition of claim 1 , wherein the composition further comprises water in an amount between 70 to 95 weight % of the composition.

6. The cleansing composition of claim 1 , wherein the composition does not contain a polyacrylate.

7. A method of cleansing skin comprising washing skin with the cleansing composition of claim 1 , and optionally rinsing with water.

8. The cleansing composition of claim 1 , wherein the composition does not contain an anionic surfactant.

9. The cleaning composition of claim 1 wherein the cationic antibacterial agent is benzalkonium chloride.
