A bactericide is added to conventional water-soluble cutting fluids to suppress deterioration by microorganisms. Such fluids are however accompanied by the drawbacks that the bactericide has a narrow antibacterial spectrum and moreover its effects last a short time. It is the object of the present invention to offers water-soluble cutting fluids which remain resistant to a wide variety of microorganisms for a long time. The present invention therefore offers water-soluble cutting fluids to which has been added a specific amine selected from amines known to date.
