Amphiphile

Chemical compound with both hydrophilic and lipophilic properties

In chemistry, an amphiphile (from Greek αμφις (amphis) 'both' and φιλíα (philia) 'love, friendship'), also referred to as an amphipath, is a dipolar chemical compound possessing both hydrophilic (water-loving, polar) and lipophilic (fat-loving, nonpolar) properties within the same molecule. Such compound is called amphiphilic or amphipathic. This dipolar characteristic implies the existence of different chemical groups forming spatially segregated regions with contrasting surface polarity.
