Propylene Glycol – USP/Industrial Grade Solvent

Propylene Glycol (PG), chemically known as 1,2-propanediol, is a synthetic organic compound used extensively as a carrier fluid, stabilizer, humectant, and solvent. It appears as a clear, viscous liquid, miscible with water, acetone, and chloroform, and is well known for its hygroscopic and non-toxic nature.

It plays a crucial role in pharmaceutical formulations, personal care products, food processing, industrial de-icing, and heat transfer fluids. In cosmetics, it retains moisture; in the food industry, it's a safe additive (E1520). In the chemical industry, it is an effective base for solvents, lubricants, and plasticizers.

Cavin Resource provides both USP-grade Propylene Glycol for food and pharma applications, and industrial-grade PG for technical uses, packed in export-ready containers.
