摘要

The friction exhibited by a flowing aqueous liquid containing a viscoelastic surfactant can be further reduced by adding to the aqueous liquid an organic electrolyte capable of associating with the surfactant ion of the viscoelastic surfactant. For example, the friction exhibited by an aqueous liquid containing cetyl trimethylammonium salicylate can be further reduced by the addition of sodium salicylate to the liquid. The resulting aqueous liquid systems exhibiting the reduced friction are shear stable and useful in a wide variety of applications.
