Soluble oil cutting fluid |
(57) A soluble-oil, suitable when diluted with water, for use as a cutting fluid comprises
an alkali or alkaline-earth metal alkyl benzene sulphonate, a fatty acid diethanolamide,
a mixed alkanolamine borate, a polyisobutenesuccinimide and a major proportion of
mineral oil. The soluble-oil is relatively stable without the need for a conventional
coupling agent and some soluble-oil emulsions are bio-static even though conventional
biocides are not included.
