Stearyl alcohol (also known as octadecyl alcohol or 1-octadecanol) is an organic compound with the formula CH₃(CH₂)₁₆CH₂OH. It is classified as a fatty alcohol. 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 of various sorts, and is widely used as a hair coating in shampoos and hair conditioners. It 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 some fats by the process of catalytic hydrogenation. It has low toxicity.^[3]
