Physico-Chemical Experiments with Phosphatidyl Ethanolamine Sols

Abstract
The solubilities of phosphatidylethanolamine (PE) in some organic solvents have been determined. The results of surface tension studies of aqueous sols of PE show that it has marked surface-active properties and surface ageing occurs. The effect of pH, concentration, mono- and divalent salts on surface activity has been investigated, and discussed in the light of previous theories. The critical micelle concentration is in the range 0·002 to 0·01 per cent w/v. The isoelectric point is at pH 3·1. The effect of mono- and divalent salts on the stability of PE sols has been studied.
