  • Publication number: 20220183946
    Abstract: The present invention is directed to a method of manufacturing a cosmetic composition comprising a step of preparing a mixture of: (a) one or more esters of sucrose and fatty acids, wherein the fatty acids are selected from those having from about 12 to about 24 carbon atoms, and wherein the sucrose esters are selected from the group consisting of mono-ester, di-ester, tri-ester, tetra-ester, and mixtures thereof; and (b) one or more solvents selected from those having 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. By the method of manufacturing the cosmetic composition of the present invention, the sucrose esters can be dissolved in the cosmetic compositions, even when the sucrose esters are contained at higher levels in the compositions and/or even when the sucrose esters are contained in an aqueous phase of the cosmetic composition.
