Abstract

See full text

Sulfonated betaines, amine oxides, and sultaines are made by the reaction of the corresponding unsaturated betaines, amine oxides or sultaines with a sulfonating agent. These amphoteric surfactants have demonstrated low adsorption properties in addition to good compatibility with brine containing high concentrations of salt and divalent cations. They can be employed in applications where their respective conventional amphoteric surfactants are used including: personal care, mining, improved oil recovery (IOR), oil field drilling, fracturing, acidizing, foaming, and agricultural formulations.
