Abstract: A skin-whitening cosmetic material which contains an unsaturated fatty acid or a derivative thereof as the active ingredient, is highly effective in making the color of pigmentation on the skin lighter at a lower concentration, and is highly safe. The skin-whitening cosmetic material comprises (A) at least one member selected from unsaturated fatty acids having from 18 to 22 carbon atoms and having from 2 to 6 double bonds in the molecular structure, and derivatives thereof, (B) a phospholipid, (C) an antioxidant, (D) at least one member selected from proteins and hydrolyzates thereof, and (E) at least one member selected from muco-polysaccharides and salts thereof.

Abstract: The invention provides a process comprising treating a lanolin fatty acid with boric acid to convert hydroxy fatty acids therein to boric acid esters, subjecting the reaction mixture to vacuum distillation to fractionate the boric acid esters of hydroxy fatty acids from non-hydroxy fatty acids, hydrolyzing the boric acid esters, and subjecting the hydrolysate to vacuum distillation to provide .alpha.-hydroxy fatty acids and .omega.-hydroxy fatty acids, the resultant respective lanolin fatty acids and esters, and cosmetic products and drug products for external use containing them.According to the invention, pale-colored, substantially odor-free lanolin fatty acids can be obtained easily and with high efficiency and these compounds can be effectively utilized in the pharmaceutical and cosmetic field.
