-84- L-2225B Title: AQUEOUS COMPOSITIONS CONTAINING CARBOXYLIC SALTS Abstract of the Disclosure A composition is disclosed which comprises water and at least one carboxylic salt dispersed or dissolved in said water, said salt being derived from: (A)(I) at least one hydrocarbyl-substituted carboxylic acid or anhydride, the hydrocarbyl substi- tuent of said acid or anhydride having an average of from about 12 to about 500 carbon atoms, or (II) at least one derivative formed by reacting at least one said hydrocarbyl-substituted carboxylic acid or anhydride with a reactant selected from the group conslsting of (a) ammonia, (b) alcohol, (c) primary amine, (d) secondary amine, (e) hydroxyamine or (f) a combination of two or more of any of (a) through (e), the components of (f) being reacted with said hydrocar- byl-substituted acid or anhydride simultaneously or sequentially in any order; and (B) at least one amine, alkali or alkaline earth metal, or alkali or alkaline earth metal compound; with the proviso that: (i) when component (A) is said hydrocarbyl- substituted carboxylic acid or anhydride, component (B) is other than an N-(hydroxyl-substituted hydrocarbyl) amine and/or hydroxyl-substituted poly(hydrocarbyloxy) analog of said N-(hydroxyl-substituted hydrocarbyl) amine; and -85- (ii) when component (A) is the reaction product of said hydrocarbyl-substituted carboxylic acid or anhydride and an N-(hydroxyl-substituted hydrocarbyl) amine and/or hydroxyl-substituted poly(hydrocarbyloxy) analog of said N-(hydroxyl-substituted hydrocarbyl) amine, component (B) is other than an N-(hydroxyl-sub- stituted hydrocarbyl) amine and/or hydroxyl-substituted poly(hydrocarbyloxy) analog of said N-(hydroxyl-substi- tuted hydrocarbyl) amine. These compositions include aqueous concentrates and water-based functional fluids.
