232 JOURNAL OF THE SOCIETY O1? COSMETIC CHEMISTS

FATTY ACIDS AND DERIVATIVES IN COSMETICS 233 oil when considered in light of its specific composition and orientation of the fatty acids present, gives some startling changes. You will note that both compounds A and B possess characteristics which are desirable to the cosmetic chemist when compared with the customary oils he has used. They are given as examples merely to demonstrate the many possibilities which exist even in the known products and reactions at our disposal. REFEI•ENCES (1) Ralston, A.
