摘要：
A water soluble lubricating additive for water-based fluids used in metalworking operations comprising a polyoxyalkylene sulfur compound selected from the group consisting of alkyl polyoxyalkylene sulfides, alkyl polyoxyalkylene sulfoxides and mixtures thereof. In an alternate embodiment of this invention, dithiodiglycol may be combined with a polyoxyalkylene sulfur compound selected from the group consisting of alkyl polyoxyalkylene sulfides, alkyl polyoxyalkylene sulfoxides and mixtures thereof to produce said water soluble lubricating additive.
