Stearic Acid is a typical example of a fatty acid, which are essentially long hydrocarbon chains containing a carboxyl group at one end and a methyl group at the other. The chain lengths can vary from 3 (propionic acid) to 24 (lignoceric acid) but the majority of fatty acids found in hydrogenated vegetable or animal oils are around C16-C20 in length. Stearic acid is a saturated acid, since there are no double bonds between neighbouring carbon atoms. Stearic acid is found in various animal and plant fats, and is a major component of cocoa butter and shea butter. Stearic acid is a very common amino acid is used in the manufacturing of more than 3,200 skin and hair care products sold in the United States. On product labels, it is sometimes listed under other names, including Century 1240, cetylacetic acid, Emersol 120, Emersol 132, Emersol 150, Formula 300 and Glycon DP. Stearic Acid is mainly used in the production of detergents, soaps, and cosmetics such as shampoos and shaving cream products. Stearic acid is used along with castor oil for preparing softeners in textile sizing. Being inexpensively available and chemically benign, stearic acid finds many niche applications It is used in the manufacture of candles, and as a hardener in candies when mixed with simple sugar and corn syrup. It is also used to produce dietary supplements. In fireworks, stearic acid is often used to coat metal powders such as aluminum and iron. This prevents oxidation, allowing compositions to be stored for a longer period of time. Stearic acid is a common lubricant during injection molding and pressing of ceramic powders. It is also used as a mold release for foam latex that is baked in stone molds. Stearic acid is known antidiabetic and antioxidant agent.

In Vivo Use Guide
Curator's Comment: When these same investigators used a lower amount of dietary stearic acid (i.e., an increase of 3 g/day using milk chocolate) in a similar study, no differences in platelet aggregation or platelet activation activity were found
A stearic acid-rich diet (~ 7% of calories or 19 g/day) had beneficial effects on several measures of thrombosis (e.g., platelet volume, platelet aggregation, coagulation factor VII activity) in healthy males. Stearic acid was increased by 12 g/day using stearic acid-enriched margarine.
Route of Administration: Oral
Inhibition of EDR (endothelium-dependent relaxation) induced by acetylcholine was dose-dependent (0.5-2 mmol/l NEFA), and the greatest inhibition (51%) was observed with stearic acid (2 mmol/l).
