L-1679 TITLE: CARBOXYLIC SOLUBILIZER/SURFACTANT COMBINATIONS AND AQUEOUS COMPOSITIONS CONTAINING SAME INVENTOR: JOHN WESLEY FORSBERG ABSTRACT OF THE DISCLOSURE: Combinations of carboxylic solubilizers, made by reac- tion of an acylating agent with an N-(hydroxyl-substituted hydrocarbyl) amine and surfactants are useful in incor- porating 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. 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.
