Chemical stability: As a saturated fatty acid, stearic acid is relatively stable chemically and is not easily oxidized. This stability prevents stearic acid from easily deteriorating or decomposing when stored for a long time and used in a variety of environments, thus maintaining the quality and performance of the product.
Product introduction
Stearic acid is a saturated long-chain fatty acid with a linear structure consisting of 18 carbon atoms, and its chemical formula is C17H35COOH (C18H36O2). It is widely found in nature, especially in animal fats and certain vegetable oils. Stearic acid is a white solid at room temperature, colorless and odorless, with low water solubility and high organic solvent solubility. In industry, stearic acid can be obtained by hydrolysis of animal and plant fats, and is widely used in food, cosmetics, pharmaceuticals, plastics and rubber industries, candle manufacturing and other fields. It is not only an important chemical raw material, but also a functional additive for a variety of products.
