Application

Lauric acid, known as dodecanoic acid, is a versatile fatty acid characterized by its 12-carbon atom chain, classifying it among medium-chain fatty acids. It is primarily valued for its role in the production of soaps and cosmetics. In these applications, lauric acid is neutralized with sodium hydroxide to produce sodium laurate, a key ingredient in soap. This process often utilizes coconut oil as a precursor, resulting in a blend of sodium laurate and other soaps. Additionally, lauric acid serves as an important intermediate in creating liquid crystals, plasticizers, and detergents. Its natural occurrence is notable in coconut and palm oils. Beyond these industrial uses, lauric acid is examined for its potential in pharmaceutical applications, such as enhancing topical and transdermal absorption and stabilizing oil-in-water emulsions. Its applications extend to being evaluated for use in aerosol formulations, demonstrating the compound's broad utility and functionality.
