Claims8
A composition for inhibiting the growth of microorganisms in metal working fluid comprising 0.5% to 55% by weight of 1,3,5-tris-(furfuryl)hexahydro-s-triazine;
- 40% to 99.5% by weight of a carrier fluid;
- and from 0.5% to 30% by weight of a surfactant.
A composition suitable for used as a premix for addition to cutting oil fluids comprising from 1% to 95% by weight 1,3,5-tris-(furfuryl)hexahydro-s-triazine;
- 4% to 99% by weight of a carrier fluid;
- and from 0% to 30% by weight of a surfactant, provided that where the carrier fluid is water, at least 0.5% by weight of a surfactant is employed.
A method of inhibiting the growth of undesirable microorganisms in metal working fluids by admixing with said metal working fluids a microbial growth inhibiting amount of 1,3,5-tris-(furfuryl)hexahydro-s-triazine.
