Definition
Meaning
A salt or ester of oleic acid.

Examples
By CEFR Level
- Sodium oleate is a common component of soap.
- The label listed ethyl oleate as an inactive ingredient.
- The researchers analysed the catalytic activity of the copper oleate complex in the reaction.
- Topical formulations often use oleates to enhance the absorption of the active pharmaceutical ingredient.
Learning
Memory Aids
Mnemonic
Think: OLEic Acid + -ATE (a common ending for salts/esters, like 'carbonATE'). So, 'oleate' is what you get from oleic acid.
Conceptual Metaphor
N/A (Too technical for common conceptual metaphors).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'олеин' (olein, a triglyceride). 'Oleate' is specifically 'олеат'.
Common Mistakes
- Mispronouncing it as /əʊˈliːt/ (oh-LEET). The stress is on the first syllable. Confusing it with 'oleic' (the adjective form of the acid). Using it as a verb (it is almost exclusively a noun).
