What is stearic acid? Benefits, Side effects, and Uses

What is stearic acid? It is a saturated fatty acid that is widely present in nature and can be derived from plants and animals. Stearic acid is rich in animal fats such as cocoa butter, shea butter and butter. Pure stearic acid is a white, odorless powder or flake with a relatively high melting point. This characteristic enables it to play a role in a wide range of applications.

Stearic acid can act as an emulsifier in the cosmetics and personal care, helping to blend oil-based and water-based ingredients into products such as face creams, lotions and soaps, ensuring a smooth and stable texture of the products. When stearic acid is used as a food additive, it can function as an emulsifier, stabilizer or thickener, which helps improve the texture of processed foods and extend the shelf life of certain foods.

Stearic acid plays a core and crucial role in the rubber industry. It is a universal vulcanization activator that can react with zinc oxide to enhance vulcanization efficiency and accelerate vulcanization crosslinking reactions. It can be used as a dispersant and lubricant to improve the dispersibility of powdered compounding agents and reduce equipment wear. It can be used as a plasticizer and softener to enhance the low-temperature flexibility of rubber, but the dosage needs to be controlled.

In practice, stearic acid can be used in tire manufacturing to improve tire performance; Improving processing performance in industrial rubber products; In the production of foam rubber, the porosity is adjusted, making it suitable for fields such as sound insulation, heat insulation, and packaging.
