Zusammenfassung:	VISCOELASTIC SURFACTANT BASED AQUEOUS FLUID SYSTEMS USEFUL AS THICKENING AGENTS IN VARIOUS APPLICATION, E.G TO SUSPEND PARTICLES PRODUCED DURING THE EXCAVATION OF GEOLOGIC FORMATIONS. THE SURFACTANTS ARE ZWITTERIONIC/AMPHOTERIC SURFACTANTS SUCH AS DIHYDROXYL ALKYL GLYCINATE, ALKYL AMPHO ACETATE OR PROPIONATE, ALKYL BETAINE, ALKYL AMIDOPROPYL BETAINE AND ALKYLAMINO MONO- OR DI-PROPIONATES DERIVED FROM CERTAIN WAXES, FATS AND OILS. THE THICKENING AGENT IS USED IN CONJUNCTION WITH AN INORGANIC WATER-SOLUBLE SALT OR ORGANIC ADDITIVE SUCH AS PHTHALIC ACID, SALICYLIC ACID OR THEIR SALTS.
