    Abstract: Combinations of carboxylic solubilizers, made by reaction of an acylating agent with an N-(hydroxyl-substituted hydrocarbyl) amine and surfactants are useful in incorporating oil-soluble, water-insoluble functional additives into aqueous systems. Typical solubilizers are made by reacting an alkyl-substituted succinic anhydride containing about 12 to about 500 carbon atoms with an alkanol amine such as diethyl ethanol amine. Typical surfactants are non-ionic hydrophilic surfactants such as ethoxylated phenols and ionic surfactants of both the anionic and cationic type. Typical functional additives are anti-wear, extreme pressure and load-carrying agents such as dithiophosphates. The aqueous systems formed with the aid of such combinations are useful, for example, as water-based hydraulic fluids.

    Abstract: PRE-TEATMENT OR POST-TREATMENT OF OIL BASE DRILLING FLUIDS FOR OIL WELL APPLICATIONS FOR PURPOSES OF STABILIZING THE FLUID AGANINST DETERIORATION UPON CONTAMINATION WITH WATER BASE DRILLING FLUIDS, WITH OR WITHOUT CLAY SOLIDS, IS EFFECTED BY ADDING TO THE OIL BASE FLUID AN AMPHOTERIC SURFACE-ACTIVE AGENT CONTAINING BOTH ANIONIC AND CATIONIC SURFACE-ACTIVE GROUPS. EXEMPLARY COMPOUNDS WHICH ARE EXTREMELY EFFECTIVE SUFACE-ACTIVE AGENTS IN THE FUNCTION ARE AMINES AND BETAINES WHICH CONTAIN ONE OR MORE CARBOXYL OR CARBOXYLATE GROUPS. ENHANCED EFFECTS ARE ALSO AVAILABLE EMPLOYING SUCH AMPHOTERIC COMPOUNDS WITH SUFONATE TYPE ANINIC SURFACE-ACTIVE AGENTS.
