Stearic Acid
Application | ||
|---|---|---|
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, also called Octadecanoic Acid, is a colorless, waxy solid that is almost insoluble in water. Its chemical formula is CH3(CH2)16CO2H. Its name stems from a Greek word meaning tallow. The salts and esters of stearic acid are called stearates. Stearic acid is one of the most common saturated fatty acids found in nature following palmitic acid. Stearic acid occurs in many animal and vegetable fats and oils, but it is more abundant in animal fat (up to 30%) than vegetable fat (typically <5%). Stearic acid is prepared by treating these fats and oils with water at a high pressure and temperature (above 200 °C), which leads to the hydrolysis of triglycerides. The resulting mixture is then distilled. In terms of its biosynthesis, stearic acid is produced from carbohydrates via the fatty acid synthesis machinery via acetyl-CoA. |
