About Diethylene Glycol
Diethylene Glycol is a colorless, odorless, hygroscopic liquid with low volatility and a sweet taste. It is a diol formed by the partial hydrolysis of ethylene oxide. DEG’s excellent solvent properties and low freezing point make it valuable in both industrial manufacturing and functional fluids.
Applications / Uses
DEG is widely used across chemical, plastic, and textile industries:
Polyester Resins: Acts as a building block in the manufacture of unsaturated polyester resins.
Solvents: Used in printing inks, dyes, and as a carrier for water-insoluble substances.
Antifreeze & Coolants: Used in functional fluids for heating and cooling systems.
Plasticizers: Applied in PVC formulations for improved flexibility and durability.
Textiles: Acts as a humectant and lubricant in fiber processing and finishing.
Cosmetics & Personal Care: Used in low concentrations as a humectant or solvent in lotions and creams.
