amphiphilic

A term used to describe a compound containing a large organic cation or anion which possesses a long unbranched hydrocarbon chain, e.g.
CH3(CH2)nCO2M+
CH3(CH2)nN+(CH3)3X (n > 7 )
CH3(CH2)nSO3M+.
The existence of distinct polar (hydrophilic) and nonpolar (hydrophobic) regions in the molecule promotes the formation of micelles in dilute aqueous solution.
