Food & Pharmaceuticals: Safe Solvent (E1520)

In food industry (E1520): Primary solvent for flavours and colours, ensuring even distribution in beverages and baked goods In pharmaceuticals, acts as a vehicle for topical, oral, and injectable medications, stabilising drug molecules that are poorly soluble in water +1

Industrial: Non-Toxic Antifreeze & Heat Transfer

Unlike ethylene glycol, Fod-processing cooling systems and solar water heater -safe if accidental leakage occurs. Effectively lowers the freezing point and raises the boiling point of aqueous solutions, protecting equipment from burst pipes and overheating

Beauty & Personal Care: Moisture Retention

As a humectant, PG prevents "drying out" of creams, lipsticks, and toothpastes. It also functions as a penetration enhancer, helping other active ingredients (like vitamins) absorb more effectively into the skin

Storage Stability

Highly stable and non-reactive. Hygroscopic (absorbs moisture) and should be kept tightly sealed.

• Storage Section

Store in a cool, dry place. For Refined/USP grades- SS (316L) or lined tanks. NO contact with galvanized steel- leads to corrosion over long periods.

Shipping

Non-hazardous for transport. Available in 1050kg IBC totes, and Flexitanks/ISO Tanks for large-volume global B2B distribution.
