Abstract: 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/cm3 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).
