Product Description

Stearic acid is an organic compound with wide application value, and its chemical and physical properties determine its important role in multiple industrial fields.
Firstly, the physical properties of stearic acid, such as its white bead like appearance, slight odor (usually described as odorless), and its solubility in different solvents, provide a foundation for its application in different processes. Its insolubility in water makes stearic acid excellent in situations where separation from the aqueous phase is required, such as food additives, cosmetic formulations, etc. Meanwhile, it is easily soluble in organic solvents such as , ether, and ethanol, which provides convenience for its chemical synthesis and purification processes.
In the food industry, stearic acid is often used as an emulsifier, stabilizer, and thickener. Due to its almost insoluble nature in water, stearic acid can form a stable emulsion at the interface between oil and water, thereby improving the texture and taste of food. In addition, stearic acid can increase the shelf life of food, prevent oil oxidation and spoilage.
In the rubber and plastic industry, stearic acid is an important additive that can improve the processing and physical properties of materials. For example, it can reduce the viscosity of rubber and plastic, making them easier to process and shape. Meanwhile, stearic acid can also improve the hardness and wear resistance of materials, thereby extending the service life of products.
In the cosmetics industry, stearic acid is often used to make cream, lotion, lipstick and other products. Its lubricity and emulsifying properties enable stearic acid to provide excellent moisturizing and nourishing effects in cosmetics. In addition, stearic acid can increase the viscosity and stability of cosmetics, improving the overall quality of the product.
In the pharmaceutical industry, stearic acid is mainly used as a lubricant and coating material for tablets. Its lubricity can reduce the friction of tablets during the compression process, improve the hardness and disintegration of tablets. At the same time, stearic acid can also be used as a coating material to protect drugs from air, moisture, and light, thereby extending the shelf life of drugs.
