Glycerin

1. Food industry: Glycerol can be used as a coloring agent in colored foods. It can also be used as a water retaining agent, carrier solvent, thickener, and plasticizer. ‌
2. Cosmetics manufacturing: Glycerol is commonly used in cosmetics as a softener, viscosity improver, and solvent. It has a mild nature and is suitable for the whole body and facial skin. It can effectively lock in moisture and prevent dryness. ‌
In the pharmaceutical field, glycerol is used to produce various formulations, solvents, desiccants, antifreeze agents, and sweeteners. It is commonly used for preparing topical ointments or suppositories. In addition, glycerol agents (solutions made by dissolving drugs in glycerol) have viscosity, anti-corrosion properties, and hygroscopicity, and are commonly used in the oral cavity, nasal cavity, ear cavity, and throat. They have moisturizing effects on the skin and mucous membranes, and can prolong the local efficacy of drugs. ‌
3. Coating industry: Glycerol is used to produce various alkyd resins, polyester resins, glycidyl ethers, epoxy resins, etc.
4. Textile and printing and dyeing processes: Glycerol is used to produce wetting agents, moisture absorbing agents, fabric anti wrinkle and anti shrink treatment agents, diffusion agents, and penetration agents.
5. High polymer materials: glycerin is often used as 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 production of alkyd paint.
Chemical properties of glycerol: It is a thick, sweet, colorless liquid obtained through the saponification reaction of fats and oils. Glycerol has viscosity, corrosion resistance, and moisture absorption properties, which make it widely used in multiple fields. ‌
