Stearyl alcohol , or 1-octadecanol , is an organic compound classified as a saturated fatty alcohol with the formula CH3 (CH2 )16 CH2 OH. It takes the form of white granules or flakes, which are insoluble in water. It has a wide range of uses as an ingredient in lubricants , resins , perfumes , and cosmetics . It is used as an emollient , emulsifier , and thickener in ointments , and is widely used as a hair coating in shampoos and hair conditioners . Stearyl heptanoate , the ester of stearyl alcohol and heptanoic acid (enanthic acid ), is found in most cosmetic eyeliners . Stearyl alcohol has also found application as an evaporation suppressing monolayer when applied to the surface of water.[ 2]
Stearyl alcohol is prepared from stearic acid or certain fats by the process of catalytic hydrogenation . It has low toxicity.[ 3]
