Diethylene Glycol (DEG) — Brief Technical Overview

Diethylene glycol is a clear, hygroscopic liquid used as a solvent, humectant, and chemical intermediate.

Chemical Identity

• Formula: C₄H₁₀O₃  
• Appearance: Colorless liquid  
• Boiling Point: ~244–245 °C  
• Solubility: Miscible with water and many organics 

Production

DEG is produced as a co‑product in the manufacture of ethylene oxide, where ethylene oxide reacts with water under controlled conditions. Adjusting reaction parameters allows producers to optimize the DEG yield alongside MEG and TEG.

Key Applications

• Resins & Polymers: Polyester resins, plasticizers, polyurethane systems  
• Solvent: In inks, dyes, oils, and textile processing  
• Humectant: In glues, tobacco, and select cosmetics  
• Coolants & Lubricants: Brake fluids and heat‑transfer fluids  

Why Industries Use It

• Excellent solvency for a wide range of materials  
• Strong moisture‑retention properties  
• High thermal stability  
• Versatility across chemical and manufacturing sectors  

Availability

High‑purity DEG is offered by Tradella Company for a wide range of industrial applications.
