Rotterdam Chemicals Group supplies high-purity Diethanolamine (DEA) for use in a variety of applications including gas treatment, surfactant production, personal care products, and corrosion inhibition. Our DEA is REACH compliant and available in industrial grade. We offer flexible packaging formats from our Rotterdam facility, including drums, IBCs and ISO tanks, shipped globally with full documentation.
What is Diethanolamine (DEA)?
Diethanolamine (CAS 111-42-2) is a viscous, colorless to pale yellow liquid with a slight ammonia-like odor. It contains both hydroxyl and amine functional groups, making it highly versatile as a neutralizer, thickener and reactive intermediate. DEA is widely used in the production of surfactants, corrosion inhibitors, and gas treating solutions.

Frequently Asked Questions (FAQ)
Can DEA be used in cosmetics?
Yes, though its use is regulated and concentration levels must comply with local cosmetic safety guidelines.
What is the difference between MEA and DEA?
DEA contains two hydroxyl groups, making it more viscous and multifunctional in formulation chemistry.
Is DEA flammable?
No, DEA is non-flammable but should still be stored in tightly sealed containers under proper conditions.
What is DEA’s role in gas treatment?
DEA reacts with acidic gases to remove them from natural gas and refinery gas streams.
