According to the same procedure as described in Preparation 1, hydroquinone and isostearoyl chloride (prepared by chlorination of isostearic acid with thionyl chloride) were reacted and the reaction mixture was extracted with ethyl acetate. The extract was washed with water and the solvent was removed. The resulting residue was thoroughly washed with water to remove unreacted hydroquinone and concentrated on a water bath at 70° C. under the reduced pressure of 1 mmHg to give hydroquinone monoisostearate.
