Lipophobicity, also sometimes called lipophobia (from the Greek λιποφοβία from λίπος lipos "fat" and φόβος phobos "fear"), 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 Latin oleum "oil", Greek ελαιοφοβικό eleophobico from έλαιο eleo "oil" and φόβος phobos "fear") refers to the physical property of a molecule that is repelled from oil.

The most common lipophobic substance is water.

Fluorocarbons are also lipophobic/oleophobic in addition to being hydrophobic.


A lipophobic coating is used on the touchscreens of Apple's iPhones since the 3GS,[1] their iPads,[2] Nokia's N9 and Lumia devices, various Samsung phones such as the Google Nexus S and Galaxy Nexus, the HTC HD2, Hero and Flyer [3] and many other phones to repel fingerprint oil, which aids in preventing and cleaning fingerprint marks. Most "Oleophobic" coatings used on mobile devices are fluoropolymer-based solids (similar to Teflon, which was used on the HTC Hero[4]) and are both lipophobic and hydrophobic.

Several products exist to restore or add a lipophobic coating to devices lacking one.
