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&#x2550;C groups, and m/z (mass/charge) value of 220-280; an oxygen content of &#x3c;5%; a density of 0.9 to 1.0 g/cmat 20&#xb0; C.; and an acid value of &#x3c;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).

Metal-working fluid compositions and methods for making

The present invention relates to an organo-functional polysiloxane of formula (1) wherein each Ris independently selected from alkyl or aryl radicals, each Ris independently selected from hydrogen, alkyl or aryl radicals, n is selected so that the molecular weight for the organo-functional polysiloxane is in the range of from 400 to 10,000, Ris a bivalent radical or &#x2014;O&#x2014;W&#x2014;(X)is hydroxy or alkoxy, z is 1, 2 or 3 and X is a reactive functional group for reacting with amine radicals and wherein 0 to 90% of &#x2014;O&#x2014;R&#x2014;(X)is hydroxy or alkoxy
