Abstract
Official abstract text for this publication.
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
Opening claim text (preview).
What is claimed is: 1. An aqueous cleansing composition comprising: a) from 2.5 to 3 weight % of the composition of a cationic surfactant which is cetyltrimethylammonium chloride; b) from 0.5 to 10 weight % of the composition of a nonionic surfactant which is a mixture of: i) lauryl/myristyl amidopropyl dimethylamine oxide; and ii) cocomonoethanolamide; and c) from 0.2 to 1 weight % of the composition of a thickener which is PEG-120 methyl glucose dioleate. 2. The cleansing composition of claim 1 further comprising a cationic antibacterial agent selected from the group consisting of benzalkonium chloride, benzethonium chloride, and mixtures thereof. 3. The cleansing composition of claim 2 , wherein the cationic antibacterial agent is benzalkonium chloride present in an amount of about 0.13 weight % of the composition. 4. The cleansing composition of claim 1 , further comprising glycerin. 5. The cleansing composition of claim 1 , wherein glycerin is present in an amount of about 2 weight % of the composition. 6. The cleansing composition of claim 1 , wherein cetyl trimethyl ammonium chloride is present in an amount of about 2.75 weight % of the composition. 7. The cleansing composition of claim 1 , wherein the composition does not contain an anionic surfactant. 8. The cleansing composition of claim 1 , wherein an amount of water is 70 to 95 weight % of the composition. 9. The cleaning composition of claim 1 further comprising a salt, optionally in an amount of 0.1 to 1.2 weight % of the composition. 10. The cleansing composition of claim 1 , wherein the composition does not contain a polyacrylate. 11. The cleansing composition of claim 1 , wherein the composition is transparent after 24 hours at 4.5° C. 12. A method of cleansing skin comprising washing skin with the cleansing composition of claim 1 , and optionally rinsing with water.
