Stearic acid is a saturated fatty acid, chemical formula is C17H35COOH, in the machinery, chemistry, medicine and other industries have a wide range of applications. The following are several main uses of stearic acid:

in the field of
1. lubricants and additives Stearic acid has very good lubricating properties and can be used in various lubricating occasions. Especially in the production and use of lubricants, stearic acid is widely used in various mineral oils, synthetic oils and other grease products, but also as a cutting fluid and printing ink materials such as additives.

the special chemical structure of stearic acid in the field of
2. plastics, which provides a good way to add stearic acid to plasticizing materials. In addition to the addition of cationic protective agents, admixtures, etc., the chemical reactions of stearic acid with other organic compounds, such as alkyd acidification, have been widely used. Stearates are an important class of plastic additives, especially in the field of PVC.

in the field of
3. detergents Because stearic acid has detergency and antibacterial properties, it can be used to make various types of detergents. Such as softeners in clothing softeners, kitchen cleaners and disinfectants.

stearic acid in the field of
4. cosmetics is naturally present in raw materials such as beeswax and body soap, and can also be used as an ingredient for adjusting skin lotions and creams. The role in skin care products includes increasing consistency, adjusting the stability of the emulsion, and having a high gloss effect.

5.

in the field of medicine Stearic acid is also one of the excipients widely used in many pharmaceuticals, with high physical stability, not easy to damage, and can maintain stability during the production and storage of drugs. The mixture of stearic acid and PEG distilled products can be used as a surface lubricant for gem surgery.

6. food field

stearic acid not only as a thickener in the food industry has been widely used, but also widely used as oil rust inhibitor, mold coating agent.
