ethanolamine
C2Technical/Scientific
Definition
Meaning
An organic chemical compound used as a building block in manufacturing, specifically a colorless, viscous liquid with both amine and alcohol functional groups.
In technical contexts, it refers to any of a group of compounds derived from this base molecule (monoethanolamine, diethanolamine, triethanolamine), widely used in industrial scrubbing, pharmaceuticals, cosmetics, and chemical synthesis.
Linguistics
Semantic Notes
The term is a combination of 'ethanol' and 'amine', describing its chemical structure. It is a hyponym of 'alkanolamine'. Its meaning is highly precise and domain-specific.
Dialectal Variation

Learning
Memory Aids
Mnemonic
Think: ETHANOL (like the alcohol) + AMINE (a nitrogen compound). It's a simple, two-part chemical name.
Conceptual Metaphor
A BUILDING BLOCK or SCAFFOLD in chemical synthesis.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'этанол' (ethanol) alone. The full term is 'этаноламин'.
Common Mistakes
- Misspelling as 'ethanolamin' (missing the 'e'), 'ethanolamine' (incorrect stress). Using it in a non-technical context where it would not be understood.

Frequently Asked Questions
It can be corrosive and cause irritation. It must be handled with appropriate safety precautions in an industrial or laboratory setting.
MEA is monoethanolamine, DEA is diethanolamine, and TEA is triethanolamine. They differ by how many ethanol groups are attached to the nitrogen atom, affecting their properties and uses.
Not typically as a direct ingredient, but some of its derivatives may be used as emulsifiers in very small amounts. It is not a common food additive.
It is a precursor for the synthesis of phosphatidylethanolamine, a critical phospholipid found in cell membranes.
