Abstract:
A method of preventing microbial growth in oil-water metalworking fluid in a machine wherein lubricating oil or hydraulic or tapping fluid can contaminate the metalworking fluid, comprises adding a partitionable anti-microbial agent, active against micro-organisms present in the metalworking fluid, to the lubricating oil or hydraulic or tapping fluid whereby an effective quantity of anti-microbial agent can migrate into the metalworking fluid to reduce micro-organism activity.A machine tool lubricating oil or hydraulic or tapping fluid composition comprises in a mineral oil or other lubricant base and an oil-water partitionable anti-microbial, active against micro-organisms present in oil-water metalworking fluids.
