CONCENTRATED LAMELLAR LIQUID PERSONAL CLEANSING COMPOSITION |
摘要 |
The invention relates to concentrated liquid cleansing compositions in lamellar phase which possess a lotion-like appearance conveying signals of enhanced moisturization. The use of a specific ratio of synthetic anionic surfactant(s) and co-surfactant(s) to fatty acid(s) in a structured liquid product was found to improve lather production by moderating or eliminating the increase in viscosity upon dilution. In a further embodiment, specific small hydrophobic molecules were found to improve freeze/thaw stability and thereby cause the inventive composition to maintain noticeable moisturization signals. |

1. An aqueous, lamellar structured, skin cleaning composition comprising:
a) about 15 to 40% by wt. of synthetic anionic surfactant(s); b) about 5 to 30% by wt. of co-surfactant(s) selected from the group of amphoteric or nonionic surfactants or blends thereof; c) about 5 to 15% by wt. of C12 to C18 linear alkyl fatty acid(s); d) wherein the synthetic anionic surfactant(s): co-surfactant(s) ratio is about 0.5 to 3; e) wherein the synthetic anionic surfactant(s) and co-surfactant(s) to C12 to C18 linear alkyl fatty acid(s) ratio is about 2 to 6; and f) an effective amount of freeze-thaw stabilizer(s) selected from isooctanol, isotridecanol, isodecanol, polyoxyethylene(2)isooctylphenyl ether and blends thereof for maintaining at least 55% of the viscosity of the composition after one freeze-thaw cycle using the standard freeze-thaw test.
