Metallic stearates are metal soaps of an 18-carbon chain fatty acid, known as stearic acid, and various alkali metals like aluminum, calcium, magnesium, and zinc. They are produced by replacing the carboxylic hydrogen of stearic acid with a metal cation from direct metal, metal oxide, metal hydroxide, metal sulphates, and metal chlorides. The most widely used metallic stearates are Calcium, Magnesium, and Zinc. The long hydrocarbon chain of stearic acid makes the stearate highly water-resistant, good for lubrication, and has a relatively higher melting point as compared to other metallic soaps. These properties allow its use in a wide range of applications, from simple plastic toys to complex structures in several industries such as polymer & rubber, pharmaceuticals & cosmetics, building & construction, and paints & coatings industry.
