Stearic acid is white flakes, beads or blocks at room temperature. solid. It is composed of saturated fatty acids mainly C16 and C18. It is insoluble in water, slightly soluble in benzene and carbon disulfide, easily soluble in hot ethanol, non-toxic and tasteless, and has the general chemical properties of organic carboxylic acids.

According to the supply of stearic acid: stearic acid has a wide range of uses and can be used as the following additives:

1. Used as lubricant, anti-sticking agent and glidant

Especially suitable for the preparation of oils and extracts. Granules, the granules produced have good fluidity and compressibility. Used as a glidant in direct compression tableting. It can also be used as a filter aid, clarifying agent and foaming agent, as well as a suspending agent and thickener for liquid preparations.

2. Used as a preservative

To prevent corrosion of electrical components such as capacitors, wax coating is usually used. Adding this product to the wax can improve the properties of the wax coating. Incorporating this product into paints and spray paints can improve their alkali resistance and water resistance.

3. Used as surface brightening agent

Stearic acid is widely used in cosmetics, plastic cold-resistant plasticizers, and release agents. , stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals and other organic chemicals. In addition, it can also be used as a solvent for oil-soluble pigments, a crayon slipper, a polishing agent for wax paper, and an emulsifier for stearic acid glycerin.

4. Used as a heat stabilizer

Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles, and films. It is a PVC heat stabilizer with good lubricity and good light and heat stabilization. In plastic PVC pipes, stearic acid helps prevent “scorching” during processing. It is an effective heat stabilizer added in PVC film processing and can prevent the finished film from being exposed to sulfides. Discoloration.

5. Used as vulcanization activator

Stearic acid plays an important role in the synthesis and processing of rubber. Stearic acid is a widely used vulcanization activator in natural rubber, synthetic rubber and latex. It can also be used as a plasticizer and softener. In the process of producing synthetic rubber, stearic acid needs to be added as an emulsifier. When manufacturing foam rubber, stearic acid can be used as a foaming agent. Stearic acid can also be used as a release agent for rubber products.

6. Used as an emulsifier

Stearic acid is used in two types of skin care products: lip balm and cold cream. This turns it into a stable and white paste. Stearic acid is also the main raw material for making almond honey and milk. Stearic acid soap esters are more widely used in the cosmetics industry.
