Propylene Glycol - Propylene Glycol

Propylene Glycol is most commonly used for the large-scale production of polymers. It is used as chemical raw material for the making of unsaturated polyester resins (UPR). It reacts with unsaturated maleic anhydride and isophthalic acid to form a copolymer. It is reacted with propylene oxide to make oligomers and polymers that are consumed for the production of widely used polyurethanes. It is useful in water-based acrylic architectural paints. It’s slow evaporation rate allows it to stop the surface from drying. It is approved for use indirectly as a food additive. It has the E-number E1520 for food applications. It is used in coffee-based drinks, liquid sweeteners, ice cream, and soda etc. It is widely used in cosmetics and pharmaceuticals. E490 is the number for cosmetic products and pharmacological products. It is applicable as a carrier or base for many types of makeup in the cosmetics industry. Acid Number:≤0.5mg KOH/L Water:≤0.5%
