Product Introduction
Propylene Glycol (PG USP) is a chemical reagent with the molecular formula C₃H₈O₂. Under normal conditions, it appears as a colorless, viscous liquid with almost no odor. Propylene glycol is a common preservative that effectively inhibits the growth of bacteria and mold. This property makes laundry detergents or detergent pods containing propylene glycol highly resistant to spoilage. Its preservative effect not only ensures the quality of the detergent or pods but also maintains the cleanliness and hygiene of clothes, preventing bacterial and fungal contamination as well as unpleasant odors.
Applications:
Used as a raw material for resins, plasticizers, surfactants, emulsifiers, and demulsifiers.
Also serves as an antifreeze and heat transfer fluid.
Functions as a carrier solvent, wetting agent, humectant, anti-caking agent, antioxidant, texture modifier, surfactant, stabilizer, thickener, emulsifier, flavoring agent, excipient, and processing aid.
Primarily used as a solvent for various fragrances, colorants, and preservatives, as well as an extraction solvent for natural flavors.
Acts as an intermediate in the production of bactericides.
As a solvent, it helps dissolve water-insoluble food additives such as preservatives, colorants, and antioxidants.
Exhibits strong hygroscopicity, providing moisturizing and antifreeze effects.
Used in cosmetics as a moisturizer, softening agent, and solvent.
In the food industry, it serves as a solvent for flavors, a softening agent for food packaging, and an anti-sticking agent.
Also employed in the production of unsaturated polyester resins, as a plasticizer for plastics, a dehydrating agent, surfactant, curing agent, and raw material for adhesives.
Additionally applied in industries such as paints and coatings.
