Lipophobicity

Lipophobicity, also sometimes called lipophobia, is a chemical property of chemical compounds which means "fat rejection", literally "fear of fat". Lipophobic compounds are those not soluble in lipids or other non-polar solvents. From the other point of view, they do not absorb fats.

"Oleophobic" (from the Greek (oleo) "oil") refers to the physical property of a molecule that is repelled from oil.

The most common lipophobic/oleophobic substance is water.

Fluorocarbons are also lipophobic and oleophobic.
