Formaldehyde has been re-classified as a class 1B Carcinogen and a class 2 mutagen. As a class 1B carcinogen it meets the criteria for exclusion and substitution. It is now possible that formaldehyde donors will be included in the requirement for exclusion and substitution.
Based on this information we are working on the removal of formaldehyde donor biocides from all our coolants. The approach will be to maintain machining performance and bio-stability.
We have designed products from synthetics, to high performance high oil coolants which are formaldehyde release biocide free.
Tests have been conducted on 3 month old samples of standard boron bio-stable coolants containing MBM or OX and both had levels of free formaldehyde >0.1%. 0.1% is the level which will require the concentrate to be labelled at H350 - may cause cancer.
Coolant HFE250H
This cutting fluid is free of formaldehyde donors and sensitising biocides. It contains a combination of phenoxyethanol and special amines to give a product with exceptional sump-life and operator comfort.
This product gives near sterile conditions in the sump and so happily meets the requirements of bacterial control required by the HSE.
John Neale Ltd has finished working on a range of lower cost ways to remove formaldehyde release biocides from water-mix cutting fluids without the loss of long-life which is inferred by this type of biocide.
Combinations of bio-stable amines and biocides have been assessed.
This development work has enabled us to create new products which offer viable cost effective alternatives to our traditional boron bio-stable coolants.
We already have premium products which are free of formaldehyde / formaldehyde release biocides.
