It is used to harden soaps, particularly those made with vegetable oil. It is also used as a parting compound when making plaster castings from a plaster piece mold or waste mold and when making the mold from a shellacked clay original. Esters of stearic acid with ethylene glycol, glycol stearate and glycol distearate, are used to produce a pearly effect in shampoos, soaps, and other cosmetic products. They are added to the product in molten form and allowed to crystalize under controlled conditions. In fireworks, stearic acid is often used to coat metal powders such as aluminium and iron. It is used along with simple sugar or corn syrup as a hardener in candies. It is used with zinc as zinc stereate as fanning powder for cards to deliver smooth fanning motion.
