Abstract

PURPOSE: To obtain pure sophorolipid useful as a cosmetic base and capable of being deodorized by the additional treatment, economically, by treating a crude sophorolipid derivative with a specific adsorbent and then hydrogenating and decoloring the treated product.
CONSTITUTION: Sophorolipid derivative I (R1 is methyl, H; R2 is 11W15C hydrocarbon group when R1 is methyl, and 12W16C hydrocarbon group when R1 is H; R3 is 1W20C hydrocarbon group; A is -CH2-CH2-0-, etc.; a+b+c+d+e+f+ g=1W60), or II is heated and stirred in the presence of an alumina adsorbent, and hydrogenated at high temperature and pressure, pref. at 50W270°C and 10W 300 hg/cm2G in the presence of a hydrogenation catalyst such as Pd, Pt, etc. The preferable examples of the alumina adsorbent are aluminium silicate, activated kaolin, activated alumina, etc.
