Abstract
The electrophoretic mobility of oil droplets, in oil in water emulsions stabilized with paraffin chain salts, have been determined, together with interfacial tension measurements on the same systems, and the observations are explained. Electrokinetic theory is discussed and an estimate made of the fraction of the gegen ions which are bound to the droplet; the value of this fraction is similar to that found by others for the spherical soap micelle.
