What is Diethylene Glycol Monoethyl Ether and how is it identified?

Diethylene glycol monoethyl ether, commonly called DEGEE, ethyl diglycol or ethoxydiglycol, has CAS 111-90-0, EINECS 203-919-7, molecular formula C₆H₁₄O₃ and molecular weight about 134.17. It is a high-boiling glycol ether solvent.

What is Diethylene Glycol Monoethyl Ether used for?

DEGEE is used as a co-solvent for paints, printing inks, dyes, resins, gums and cellulose systems. It also serves as a mutual solvent in mineral-oil soap or sulfurized-oil mixtures and is used in cleaners, non-paint colorants and fiber-processing products.

Why is DEGEE useful as a co-solvent?

DEGEE is fully miscible with water and compatible with many organic coating and ink components, so it can help couple aqueous and nonaqueous ingredients. Its high boiling point also helps control evaporation in coatings, cleaners and printing applications.

Which specifications should be confirmed when purchasing DEGEE?

Confirm assay, water content, color, acidity and peroxide value. The required purity and water content should match the solvent, coating, ink or cleaner formulation because these parameters can affect clarity, odor and long-term stability.

How should Diethylene Glycol Monoethyl Ether be stored and handled?

Store DEGEE in tightly closed containers in a cool, ventilated area away from heat, sparks, open flames and strong oxidizers. It is flammable, so use vapor controls and appropriate chemical-resistant PPE when handling the solvent.
