Product details

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
