PURPOSE:To prepare cosmetics having excellent color, odor, stability and applicability, and uniform qualities, by compounding a product obtained by the esterification of trimethylolpropane with a >=8C fatty acid (monobasic acid) and a >=12C dibasic acid, as a base. CONSTITUTION:Trimethylolpropane is esterified with a monobasic acid comprising a >=8C straight or branched chain saturated and/or hydroxy-fatty acid, e.g. lauric acid, and a >= 12C straight or branched chain dibasic acid (e.g. dodecane dicarboxylic acid) to obtain a mixed esters composed mainly of a compound of formula (R1-R4 are H or acyl derived from the above monobasic acid; X is alkylene derived from the above dibasic acid). The product is suitable as a base of comsmetics because of its high affinity, adhesivity and moistening property to the skin, colorlessness, odorlessness, chemical inactivity, moderate sticking power, high compatiiblity with wax, solubility in castor oil, drug dissolving power, etc. |
