Stearic Acid

Stearic acid

Stearic acid is a chemical compound consisting of an 18 carbon chain whose terminal carbon is connected to an oxygen atom with a double bond and a hydroxyl group (OH) by a single bond. It belongs to class of materials known as fatty acids, produced primarily from natural fats and oils. Stearic acid is an important component in soap and other cosmetic and industrial preparations.

Stearic acid is derived predominantly from fats and oils. These materials contain triglycerides which are glycerine molecules attached to long hydrocarbon chains. These hydrocarbons can be removed from the glycerine backbone through a variety of techniques. When a triglyceride molecule is split, it yields three molecules of fatty acid and one molecule of glycerine. The major fat used in the production of stearic acid is beef fat, also known as tallow. Stearic acid is also obtained in lesser amounts from herring and sardine. Plant oils such as cotton, coconut, palm kernel, castor beans, rapeseed, soybeans, and sunflowers are also natural sources. In the United States, almost all stearic acid is made from tallow and coconut oil, although lesser amounts are made from palm oil. The other plant sources are more commonly used in third world countries.

Historically, stearic acid has been made by a process known as hydrolysis, which involves heating the fat in an alkaline solution. This process is also known as saponification. The alkali that is traditionally used is sodium hydroxide, also known as caustic soda or lye. Hence the term "lye soap." Other methods used to produce fatty acids include solvent crystallization, hydro-genation, and distillation.
