Abstract: Substantially oil-free aqueous industrial fluids comprise (A) up to as much as 99.9 percent by weight water, (B) at least one substantially water-insoluble functional additive stably dispersed in the water and (C) at least one substantially water-soluble liquid organic dispersing agent, said dispersing agent being capable of dispersing said functional additive in said fluid and are useful as liquids in a variety of industrial applications, such as hydraulic systems and metal shaping operations. Typically, these compositions also contain at least one water-soluble polymeric thickener and at least one corrosion inhibitor. Methods for preparing these fluids from concentrates are also disclosed.
