    摘要： Cosmetic compositions, kits thereof, and methods of making and using such cosmetic compositions. The cosmetic compositions typically include about 20 to about 95 wt. % of a polyol; about 5 to about 70 wt. % of one or more monoalcohols having from 2 to 6 carbon atoms; about 0.1 to about 10 wt. % of one or more cationic surfactants; about 0.1 to about 20 wt. % of one or more fatty compounds; and about 1 to about 15 wt. % of a combination of a urea compound and citric acid, wherein all weight percentages are based on the total weight of the cosmetic composition. The cosmetic compositions have a weight ratio of polyol to monoalcohol(s) that is from 20:1 to 1:20. Additionally, the cosmetic compositions typically have a mole ratio of citric acid to urea compound of that is about 10:0.5 to about 0.5:10.

    摘要： A method of manufacturing a cosmetic composition by preparing a mixture that includes a sucrose esters and one or more solvents. The sucrose ester can have a fatty acid portion having from about 12 to about 24 carbon atoms and the sucrose esters can be selected from the group consisting of mono-ester, di-ester, tri-ester, tetra-ester, and mixtures thereof. The one or more solvents can have Hildebrand Solubility Parameter of from about 23 to about 31.5(J/cm3)1/2 and Polar component of Hansen Solubility Parameter of from about 4.5 to about 10.5 (J/cm3)1/2. The sucrose ester can be dissolved in the cosmetic compositions, even when the sucrose ester is contained at higher levels in the compositions and/or even when the sucrose esters are contained in an aqueous phase of the cosmetic composition.
