Stearic acid is a saturated fatty acid with an 18-carbon chain. The IUPAC name is octadecanoic acid. It is a waxy solid chemical, in general the applications of stearic acid exploit its bifunctional character, with a polar head group that can be attached to metal cations and a nonpolar chain that confers solubility in organic solvents. The combination leads to uses as a surfactant and softening agent. Stearic acid is mainly used in the production of detergents, soaps, and cosmetics such as shampoos and shaving cream products. Being inexpensive, nontoxic, and fairly inert, stearic acid finds many niche applications. Like negative plate additive in lead-acid batteries. Stearic acid is used along with simple sugar or corn syrup as a hardener in candies. In fireworks, stearic acid is often used to coat metal powders such as aluminium and iron.
