Glycerin (also known as Glycerol) is an important organic compound with clear chemical identifiers: its chemical formula is C3H8O3 , CAS No.: 56-81-5. According to different application scenarios, it is mainly divided into two categories: industrial-grade glycerin and food-grade glycerin. Both categories have a stable purity of 99.5%, which meets the strict purity requirements of different fields. It has a wide range of sources: it can be extracted and purified from animal fats and vegetable oils, and it is also a key by-product in the industrial process of producing biodiesel from triglycerides. From a biochemical perspective, glycerin is the core skeleton component of triglyceride molecules. When triglycerides are metabolized and decomposed in organisms, they eventually produce two products: glycerin and fatty acids. This also reflects its important role in biological metabolism.

| Application Field | Specific Functions | Applied Products / Scenarios |
| Chemical Field | Basic raw material for synthesizing various chemical products. | Epichlorohydrin (for epoxy resins), propylene glycol (for cosmetics/pharmaceuticals), ethylene glycol (for antifreeze), dihydroxyacetone (for food/cosmetics) |
| Coating Field | Used to produce resins (alkyd resins, polyester resins, epoxy resins, etc.); replaces quick-drying paints and enamel paints, and improves insulation performance. | Insulating coatings for electrical materials, various coatings/paints |
| Rubber Field | Aids in the dispersion of fillers (improves processability), softener (enhances flexibility), lubricant for water bladders (prevents cracking), release agent (prevents adhesion). | Rubber products (low-hardness products), rubber water bladders, rubber mold release |
| Metal Processing Field | Lubricant (reduces friction and damage), rust-proof, anti-corrosive, and anti-oxidative (protects metal surfaces). | Metal pickling, quenching, stripping, electroplating, galvanizing, welding |
In the food industry, glycerol can also be used as a sweetener and humectant, applied in baked goods, dairy products, processed fruits and vegetables, cereal products, and sauce condiments. It also has the functions of moisture retention, oxidation resistance, and alcoholization promotion. Meanwhile, it is a humectant and flavor solvent for tobacco. In the daily chemical field, in addition to being used in skin care products such as creams, facial masks, and facial cleansers for moisturizing, viscosity reducing, and denaturation, glycerol can enhance the decontamination ability of detergents, improve their resistance to hard water, and increase their antibacterial properties when added to detergents. Furthermore, it is also used in textile printing and dyeing (for lubrication and moisture absorption), leather industry (for increasing softness and elasticity), paper industry (for preventing brittleness), ink industry (for preventing drying), photography industry (as a component of developer solutions), and national defense industry (for manufacturing special materials).
