An overbased calcium magnesium sulfonate grease composition and method of making such grease without using any conventional non-aqueous converting agents, such as hexylene glycol, as a pre-conversion ingredient. The addition of magnesium sulfonate as an ingredient prior to conversion appears to act as a new, non-conventional converting agent, resulting in greases with improved thickener yield and excellent dropping point.

A wear-indicating metalworking fluid is provided that includes a lubricant base; and a wear-indicating agent. A method of determining wear in a metalworking fluid includes providing wear-indicating metalworking fluid that contains a lubricant base and a wear indicating agent; and observing the visual appearance of the metalworking fluid. A change in visual appearance of the metalworking fluid when compared to an unused metalworking fluid indicates wear of the metalworking fluid.

The disclosure relates to a biobased metal-working fluid (MWF) composition and method for making same, and more particularly metal-working fluid with biobased lubricants with improved emulsion stability. At least 50 wt. % of the base oil component in the MWF concentrate is a plant-derived liquid decarboxylated rosin acid oil (“DCR”). The DCR comprises 50 to 100 wt. % of tricyclic compounds having 18-20 carbon atoms, one or more C═C groups, and m/z (mass/charge) value of 220-280; an oxygen content of <5%; a density of 0.9 to 1.0 g/cm.sup.3 at 20° C.; and an acid value of <10 mg KOH/g. The resulting MWF is characterized as having comparable if not better performance compared to a MWF containing only mineral oil (e.g., Group I or Group II).

The present invention provides a water-soluble metalworking oil composition, including: 5.0 to 20.0 mass % of a sulfur compound (A) that is one or more kinds selected from the group consisting of a sulfurized fat and oil and a sulfurized ester and has a kinematic viscosity of 10 to 800 mm.sup.2/s at 40° C.; 0.5 to 20.0 mass % of the nonionic surfactant (B) having an HLB of 6 to 18; 7.0 to 30.0 mass % of an unsaturated fatty acid polymer (C); and an amine compound (D) selected from the group consisting of a tertiary amine and a secondary amine.
