Abstract
A new esterification reaction product is obtained by an esterification reaction between an intermolecular oligo-esterification carboxylic acid of 12-hydroxy stearic acid and/or ricinoleic acid and sterol. Also, a mixture of a sterol ester of the oligo-esterification carboxylic acid and a sterol ester of the above fatty acid is obtained by reacting directly 12-hydroxy stearic acid and/or ricinoleic acid with sterol. These esterification reaction products have a good emulsifying property, hydrating property and moisture retaining property and are useful for an oil base of cosmetics and endermic liniments.
