Main purpose:

1. Glycerin is an important organic chemical raw material and is widely used in many sectors of the national economy. It is an excellent hygroscopic agent, antifreeze agent, lubricant, solvent and co-solvent, and an important raw material for the production of polyester, nitroglycerin, medicine, etc.

2. In the food industry, it can be used as a water-retaining agent (for bread, cakes), a carrier solvent (for flavors, pigments, water-insoluble preservatives), a thickener (for beverages, wine preparation, etc.), a plasticizer (for confectionery, desserts, meat products, etc.); it can be used as a color carrier in colored foods. Glycerin can also be used as a lubricant for food processing and packaging machinery.

  3. It is often used as a softener, viscosity improver and solvent in the manufacture of drugs and cosmetics.

  4. Among polymer materials, glycerin is often used as a raw material for the production of polyurethane foam, polyether, etc. It is an important raw material for the production of alkyd resin and celluloid, especially in the manufacture of alkyd resin paint.

  5. It is also widely used in tobacco industry, ceramic industry, leather industry, wood industry and photography. And used as an antifreeze for automobiles and aircraft fuels and oil fields.

  6. Used as analytical reagent, gas chromatography fixative. Boron complexing agent.
