Diethylene Glycol

Diethylene Glycol (DEG) is a colorless, odorless, slightly sweet liquid that is fully miscible with water, alcohols, and ethers. It has low toxicity but prolonged exposure may cause skin or respiratory irritation.

Formula:: C₄H₁₀O₃
CAS:: 111-46-6
Min. Order:: 25KG
Molecular Wt:: 106.12
Melting Pt:: -6.5°C
Appearance:: Colorless, transparent, odorless, slightly sweet liquid
Application:: Chemical Industry:
Solvent for natural gas dehydration, aromatic separation, textile lubrication, nitrocellulose, resins, oils, and printing inks.
Intermediate in polyester resins and plasticizer production.

Pharmaceutical Field:
Solvent and excipient in drug formulation and packaging.
Humectant in certain medications.

Food Industry:
Humectant and solvent in regulated food applications.
Detection and extraction of food components.

Cosmetics & Personal Care:
Humectant and solvent to enhance smoothness and moisture retention.
Thickening agent for skin-softening effects.

Antifreeze:
Used in automotive and aviation antifreeze and refrigerants to lower freezing point.

Electronics Industry:
Cooling and cleaning fluid for electronic device manufacture and maintenance.
Packaging:: Packaged in plastic or glass containers: 25 kg and 200 kg drums. Small sizes (100 g, 500 g) available for laboratory use.
Storage:: Store in a cool, dry, ventilated area away from direct sunlight and high temperatures. Keep containers tightly sealed to prevent leakage and moisture uptake. Keep away from ignition sources and strong oxidizers. Periodically inspect packaging for integrity.
Transportation:: Use dedicated, well‑sealed vehicles. Inspect packaging before shipment and replace any damaged containers. Maintain smooth transport to avoid shocks. Personnel must wear gas masks, chemical‑resistant goggles, protective clothing, and gloves.
Summary:: Diethylene Glycol is a versatile organic compound used as a solvent, humectant, intermediate, and antifreeze agent across chemical, pharmaceutical, food, cosmetics, and electronics industries. Its high boiling point and low volatility make it suitable for extreme temperatures, but safety precautions are required due to its irritant properties.
