TL;DR:
A novel type of biphasic separation in aqueous solutions of mixed cationic-anionic (catanionic) surfactants induced by hexafluoroisopropanol (HFIP) is described and suggests the formation of a catanionic complex in the coacervate phase through ion pairing with a concomitant release of the surfactant counterions into the aQueous-rich phase.

author keywords: selectivity; linear solvation energy relationships; micellar electrokinetic chromatography; surfactants
