INTERFACIAL TENSION OF ALIPHATIC ALCOHOLS AND AROMATIC LIQUIDS WITH SURFACE ACTIVE AGENTS. PART I

Measurements of the interfacial tension of some alcohols and aromatic liquids have been carried out against soap solutions. The tension at the oil droplet interface with increasing soap concentration is initially found to fall rapidly for dilute solutions, and thereafter reach a limiting value, when further increase in soap con­centration has practically no effect, except in cases of n-hexyl and sec.-octyl alcohols which show a maximum in dilute gasp solutions, followed by a rapid lowering.
