⭐ What Is DEG (Diethylene Glycol)?

Diethylene Glycol (DEG) is a colorless, low-viscosity diol with a slightly sweet odor.
With the chemical formula C₄H₁₀O₃, DEG is widely used as a solvent, humectant, plasticizer, polymer intermediate, and chemical raw material in many industrial applications.

It is a member of the ethylene glycol family.
