Glycerol (also called glycerine or glycerin) is a simple polyol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in all lipids known as triglycerides. It is widely used in the food industry as a sweetener and humectant. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature.
1. Used to make nitroglycerin, alkyd resin and epoxy resin.
2. In medicine, it is used to prepare various preparations, solvents, hygroscopic agents, antifreeze and sweeteners, and to prepare external ointments or suppositories.
3. In the coating industry, it is used to prepare various alkyd resins, polyester resins, glycidyl ethers and epoxy resins.
4. Used in the textile and printing and dyeing industries to prepare lubricants, moisture absorbents, fabric anti-shrinkage treatment agents, diffusing agents and penetrants.
5. In the food industry, it can be used as a sweetener, hygroscopic agent and solvent for tobacco agents.
6. It is widely used in papermaking, cosmetics, tanning, photography, printing, metal processing, electrical materials and rubber industries.
7. It is also used as fuel for automobiles and airplanes as well as antifreeze in oil fields.
8. Glycerin can be used as a plasticizer in the new ceramic industry.

Glycerol (also called glycerine or glycerin) is a simple polyol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in those lipids known as glycerides. Due to having antimicrobial and antiviral properties it is widely used in FDA approved wound and burn treatments. It can also be used as an effective marker to measure liver disease. It is also widely used as a sweetener in the food industry and as a humectant in pharmaceutical formulations. Owing to the presence of three hydroxyl groups, glycerol is miscible with water and is hygroscopic in nature.
APPLICATION:
It is an ingredient of processing aid in cosmetics, toiletries, personal care, drugs, and food products. Its functions act as a denaturant, humectant, solvent, and perfuming.
Scope
Biodiesel free and total glycerin has a thermal conductivity detector, hydrogen flame ionization, electron capture, flame photometric, five kinds of nitrogen and phosphorus detector can be equipped with a packed column or a capillary column. The instrument can be programmed temperature thermostat operation, or third-order operation. Instrument is highly integrated, advanced design, to achieve a higher degree of automation, it can detect parameters, temperature parameters set by the keyboard implementation. Can packed column and capillary pressure and stigma real-time display, the instrument uses a single air route structure, reasonable structure, stable and reliable performance, simple operation, easy maintenance.
