Detangling shampoo patented by Unilever.* U.S. Patent No. 7,541,320 B2; Unilever Home & Personal Care USA has patented a mild aqueous shampoo with excellent detangling and conditioning properties. It is comprised of approximately 68% of an alkyl alkyl /al·kyl/ (al´k'l) the monovalent radical formed when an aliphatic hydrocarbon loses one hydrogen atom. al·kyl n. ethoxy eth·ox·y n. The univalent radical C2H5O. adj. Relating to or containing the ethoxy radical. sulfate surfactant Surfactant Definition Surfactant is a complex naturally occurring substance made of six lipids (fats) and four proteins that is produced in the lungs. It can also be manufactured synthetically. wherein the alkyl group has an average of 12-16 carbon atoms and the degree of ethoxylation is at least 3; from about 2-7% of a betaine betaine /be·ta·ine/ (be´tah-en) the carboxylic acid derived by oxidation of choline; it acts as a transmethylating metabolic intermediate and is used in the treatment of homocystinuria. surfactant; from about 2-7% of a hydroxysultaine surfactant; from about 0.1-5% of a non-volatile, water-insoluble silicone; at least about 70% water; and less than 2% of an added surfactant selected from the group consisting of alkyl sulfates and alkyl or alkyl aryl ar·yl n. An organic radical derived from an aromatic compound by the removal of one hydrogen atom. sulfonates, ethoxylated alkylphenols and ethanolamides of aliphatic acids. The weight ratio of the betaine surfactant to the hydroxysultaine surfactant is in the range from 0.5-1.5, and the weight ratio of the alkyl ethoxy sulfate surfactant to the sum of the weights of betaine surfactant and hydroxysultaine surfactant is in the range from 0.5-1.5. The composition has a wetcombing force less than approximately 20 gm-force as measured by the wet and dry combing force in-vitro assay. |
