Part of speech: adjective

Definitions

3. The expression relates to the characteristic of materials that preferentially bond with lipids, emphasizing a tendency to interact more favorably with oily substances than aqueous ones

Etymology: Oleophilic is a plain technical coinage: it combines "oleo-", from Latin "oleum" meaning oil (itself from Greek "elaion", olive oil), with "-philic", from Greek "philos", meaning loving or having an affinity for. Put together, the word describes a substance that is drawn to oil rather than water. The pairing is a common pattern in chemistry and materials science, where "-philic" marks an attraction to a given substance and "-phobic" marks repulsion. Its opposite, "hydrophilic", attracts water, and the two terms are often used side by side to describe how a surface or molecule behaves toward each kind of liquid.
