The terms lyophilic (
hydrophilic,
lipophilic,
oleophilic, etc.) and lyophobic (
lipophobic, etc.) may be used to describe the character of interaction of a particular atomic
group with the medium. In this usage the terms have the relative qualitative meaning
of '
solvent preferring' (water-preferring, fat-preferring, etc.) and '
solvent rejecting' (water-rejecting, fat-rejecting, etc.) respectively.
