Stearic acid is used as a raw material in the production of detergents, surfactants, soaps, and cosmetics such as shampoos and shaving cream products. Its salts are used to soften polyvinyl chloride and a component of grease. It is used for the preparation of softeners in textile sizing with castor oil and dietary supplements. It acts as a hardener in candles with simple sugar or corn syrup. It is utilized for the coating of metal powders like aluminum and iron in fireworks. It finds application as a common lubricant during injection molding and pressing of ceramic powders. It acts as a key raw material for the synthesis of stearyl alcohol by reduction.
