Viscoelasticity in aqueous soap solutions. Part 4.—Effect of alcohols

Abstract

Measurements have been made of the viscoelastic properties of some gels formed by adding electrolytes and long-chain alcohols to aqueous solutions of potassium and ammonium oleate. Hexanol, decanol and tetradecanol tend to decrease the viscoelasticity; octadecanol and docosanol tend to increase it. The results have been explained in terms of the formation of secondary micelles containing both soap and alcohol molecules. An estimate is made of their size on the basis of the kinetic theory of rubberlike elasticity.
