The present invention relates to an aqueous composition comprising three components. The first component is a primary detergent, non-ionic surfactant with a critical packing parameters (CPP) of &#x2267;0.95. The second component is a inorganic particle whose surface has been modified to improve stability. The third necessary component is a secondary surfactant with a CPP of &#x2266;0.85. The secondary surfactant can function to improve the overall cleaning performance, the streaking performance and provide overall formulation stability.

The present invention relates to a process for the minimization of volatile organic sulphur byproducts in dimethyl sulfate quaternization of amines made with hypophosphorous acid, which leads to the formation of an odor stable product.

A method for controlling the rheology of aqueous systems, particularly for those intended for underground use, includes injecting an aqueous viscoelastic fluid containing a surfactant gelling agent into the system. The viscoelastic surfactant composition of the invention comprises, as a gelling agent, at least one fatty aliphatic amidoamine oxide in a glycol solvent. The composition also maintains the levels of free fatty acid and free amine within critical parameters in order to achieve superior performance. The additives may be incorporated in the viscoelastic fluid to tailor its use in stimulation fluids, drilling muds, fracture fluids, and in applications such as permeability modification, gravel packing, cementing, and the like.

Viscoelastic surfactants and compositions containing same

The present invention generally relates to a textile softening composition which comprises, as the softening agent, a quaternary ammonium salt which comprises a mixture of mono-, di- and tri-ester components, wherein the amount of diester quaternary is greater than about 50% by weight, and the amount of triester quaternary is less than about 25% by weight based on the total amount of quaternary ammonium salt. The invention also relates to a softening agent which comprises a high diester quaternary ammonium salt mixture comprising mono- and diester components derived for ether dialkanolamines. The invention also relates to processes for preparing said softening agents, and methods of use as a fabric softener and as a hair and skin conditioner.
