DEG (Diethylene Glycol)

Formula

Description

Diethylene Glycol (DEG-2, 2-Dihyroxydi Ethyl Ether) is a colorless, virtually odorless, viscous liquid. Compared to MEG, it has a higher boiling point, viscosity and specific gravity. DEG is characterized by great solvent power, extreme hygroscopicity and low vapor loss.
