Product Uses
We markets two grades of PG to meet the requirements of the various applications. PG is used in a wide range of applications, including:
☆ USP/EP/Pharma Grade: (食品级、医药级)
- Solvent in the flavor concentrate and fragrance industry, an excipient in elixirs and pharmaceuticals, and a coupling agent in sunscreens, shampoos, shaving creams and other personal care products
- Wetting agent for natural gums to simplify compounding
- Humectant, preservative and stabilizer in diverse applications like baked goods, flavorings, salad dressings, shave creams, pet food (except cat food)
☆ Industrial/Technical Grade: (工业级)
- Raw material to produce high-performance unsaturated polyester resins (UPR) used for marine construction, gel coats, sheet molding compounds and synthetic marble castings
- Chemical intermediate in the production of resins for paints and varnishes
- Solutions with water to make antifreeze, heat-transfer fluids and aircraft and runway deicing fluids
- Solvent in printing inks
- Solvent and enzyme stabilizer in laundry detergents
- Stabilizer in hydraulic fluids
- Plasticizer to improve the processability of plastic
