Stearic Acid is one of the most common long-chain fatty acids. It is found in combined form in natural animal and vegetable fats. Commercial stearic acid is a mixture of approximately equal amounts of stearic and palmitic acids and small amounts of oleic acid. It is employed in the manufacture of candles, cosmetics, shaving soaps, lubricants, and pharmaceuticals.
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.
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.
Stearic acid is also 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.
