What is Stearic Acid? Great applications of Caviar Wax

Industrial chemicals are growing stronger and stronger, and are present in almost all manufacturing industries. Among them, Stearic Acid stands out with its great advantages. So what is Stearic Acid? What are the great applications of Stearic Acid? Let's learn about this chemical known as "fish egg wax" with VNT.

Applications of Stearic Acid

1. What is Stearic Acid?

Stearic acid (caviar wax) is a saturated fatty acid consisting of an 18-carbon chain, with the chemical formula CH3-(CH2)16-COOH and the IUPAC name is octadecanoic acid. This substance is present in many animal fats and vegetable fats, but is more common than vegetable fats (usually containing stearic acid content <5%) is animal fat (accounting for about 30%). In addition, there are some exceptions such as cocoa butter and shea butter which can contain stearic acid content as high as 28-45%.

3. Applications of Stearic Acid in Life

- In general, the applications of stearic acid exploit its bifunctional character, itself with a polar head group that can be attached to metal cations and a non-polar chain that confers solubility in organic solvents. Such a combination leads to its use as a surfactant and softener.

- Stearic acid is mainly used as a raw material for the production of dry stearate desiccants, lubricants, soaps, pharmaceutical technology, household goods. In addition, stearic acid is a dispersant and softener in rubber, paper and metal surface polishing, surface coatings, food wrapping paper, etc.

Applications of Stearic Acid

– Stearic Acid is used as a release agent when making plaster from a plaster mould, to do this the stearic acid powder is dissolved in water and the mixture is brushed onto the surface of the mould before the plaster is added to release the product after casting.

– Stearic Acid is an ingredient in candles, soaps, plastics, dietary supplements, talcum powder and cosmetics and to soften rubber. Stearic Acid is used to harden soaps, especially those made from vegetable oils.

Stearic acid salts of zinc, calcium, cadmium and lead are used to soften PVC plastic. Stearic acid is used together with castor oil as a softener in textile sizing. They are heated and mixed with caustic soda or caustic soda.

– In the field of fireworks production, due to its anti-oxidation properties, stearic acid is often used to coat metal powders such as aluminum and iron.

– Stearic acid esters with ethylene glycol are used to create pearlescent effects in shampoos, soaps and some cosmetics; used with simple sugars or corn syrup as hardeners in candy.

– Stearic acid is used to produce dietary supplements. Dietary stearic acid has 2.4 times more desaturated oleic acid than palmitic acid to convert to palmitoleic acid. In addition, stearic acid rarely combines with fatty esters. Research has also shown that stearic acid is less harmful to health than other unsaturated fatty acids.

– Stearic acid is used as a common lubricant in the ceramic casting process. It is also used as a mold to create rubber foam baked in stone molds.

– Stearic Acid provides emulsifying properties, helps increase porosity, product thickness and is considered an emulsifier that helps combine with water and oil in lotion and cream formulas. The effect of Stearic Acid in skin care cosmetics is undeniable. Stearic Acid has moisturizing, soothing, antibacterial and anti-inflammatory effects on the skin.
