Abstract
PURPOSE: To obtain a pure carboxylic acid ester useful for a cosmetic base having improved heat and storage stability with little discoloration without requiring the decoloring step, by esterifying a carboxylic acid pretreated with phosphoric acid with an alcohol.
CONSTITUTION: 100pts.wt. of a carboxylic acid obtained from a 4W22C synthetic or animal and vegetable fat and oil, e.g. stearic acid, brought into contact with 0.1W10pts.wt., preferably 0.5W3.0pts.wt., of phosphoric acid or polyphosphoric acid (P) at 50W150°C with stirring for 20W120min, and the acids are separated to remove P from the lower layer. The pretreated carboxylic acid is esterified with an alcohol in the presence or absence of an esterification catalyst. The unreacted carboxylic acid is neutralized with an alkali, and washed with water to remove the carboxylic acid soap. The washed product is then dehydrated to give the purified carboxylic acid ester, e.g. methyl stearate.
