Abstract
Shear stable antimisting properties are provided to a wide variety of formulations comprising aqueous liquids through the use of a viscoelastic surfactant which comprises a surfactant compound having a hydrophobic moiety chemically bonded to an ionic, hydrophilic moiety and an electrolyte having a moiety that is capable of associating with the surfactant ion. Optionally, an additional amount of electrolyte can be added to the viscoelastic surfactant to further reduce misting. The viscoelastic surfactant can also be a nonionic surfactant.
