    摘要: Bleach compositions, such as aqueous sodium hypochlorite formulations, are thickened by admixing the composition with a viscoelastic surfactant. Visco-elastic surfactants comprise surfactant ions and organic counterions that associate in the bleach composition to form the viscoelastic surfactant. Thickened bleach compositions of this invention exhibit bleach stability, phase stability, and viscosity stability for acceptably long periods of time. The thickened bleach compositions can be employed as nonmisting sprays and streams which will stick to vertical surfaces without substantial dripping and can be applied to various substrates using a dispensing device.

    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.

    摘要: Onium species of nitrogen, phosphorus or sulfur are useful to precipitate ferric ion, existing as tetrahaloferrate anion, from strong haloacid solutions. The precipitants are useful in the field of well acidizing, because tetrahaloferrate anion attacks polymeric and viscoelastic surfactant thickeners used to thicken haloacid solutions.
