Patent ID: 7541320

Claim:
A mild aqueous shampoo composition having excellent detangling and conditioning properties comprising: i) about 6 to about 8% of an alkyl ethoxy sulfate surfactant wherein the alkyl group has an average of 12-16 carbon atoms and the degree of ethoxylation is at least 3, ii) from about 2% to about 7% of a betaine surfactant, iii) from about 2% to about 7% of a hydroxysultaine surfactant, iv) from about 0.1% to about 5% of a non-volatile, water-insoluble silicone, v) at least about 70 wt % water; vi) less than about 2% of an added surfactant selected from the group consisting of alkyl sulfates and alkyl or alkyl aryl sulfonates, ethoxylated alkylphenols and ethanolamides of aliphatic acids; wherein the weight ratio of the betaine surfactant to the hydroxysultaine surfactant is in the range of from about 0.5 to about 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 of from about 0.5 to about 1.5; wherein the composition is not a potential eye irritant as measured by having either a Zein solubility of less than about 1% as measured by the Zein Solubility In-Vitro Assay or a % permeability of fluorescein leakage less than about 10% as measured by the Fluorescein Leakage Assay; and wherein the composition has a wet-combing force less than about 20 gm-force as measured by the Wet and Dry Combing Force In-Vitro Assay.
