Stearic acid

　　Main Uses

　　Industrial Field:

　　Lubricant: Used in plastic and rubber processing to reduce friction between materials and equipment and improve processing performance (e.g., PVC pipes, tire production).

　　Release Agent: Used in metal casting and plastic molding to prevent products from sticking to molds.

　　Raw Material for Surfactants: Reacts with alkalis to form stearates (e.g., sodium stearate is the main component of soap; zinc stearate is used as a stabilizer in coatings and rubber).

　　Textile Auxiliaries: Used for softening treatments and waterproof finishing of textiles.

　　Daily Chemical Field:

　　It is a main component of cleaning products such as soaps, body washes, and facial cleansers. It functions as a surfactant by reacting with alkalis to exert a decontamination effect.

　　Used as an emulsifier and thickener in skincare products (e.g., creams, lip balms) to enhance product stability and texture.

　　Used as a waxy component in cosmetics to adjust product hardness (e.g., lipsticks, mascaras).

　　Pharmaceutical Field:

　　Used as a pharmaceutical excipient as a base for ointments and suppositories to adjust the hardness and melting point of preparations (e.g., rectal suppositories need to melt at body temperature to release the drug).

　　Used as a lubricant in tablets to reduce the adhesion of materials to molds during tableting and to improve the appearance and disintegration properties of tablets.

　　Other Applications:

　　Used in food additives (e.g., lubricants, defoamers), but must comply with food-grade standards (GB 1886.91-2016).

　　Used as a raw material for candles to improve hardness and combustion stability.
