ABSTRACT
Cosmetics are composed of oleaginous raw materials (oils, waxes, hydrocarbons, higher fatty acids, higher alcohols, esters, silicones, etc.), surfactants, humectants, polymers, ultraviolet absorbents, antioxidants, sequestering agents, coloring ma terials (pigments, lakes, and dyes), fragrance materials, and biologically active substances (vitamins, hormones, amino acids, etc.). Oleaginous raw materials have been widely employed to improve various characteristics of cosmetics (e.g., gloss, fluidity, molding, and hardness), they are important for the preparation of oleaginous solid cosmetics, especially point-makeup cosmetic pencils such as lipstick, rouge, eye shadow, and eyeliner.
