Peter's post reminds me that anatomists sometimes tamper with their recipes by altering the proportions. We had an experience some time ago where they upped the methanol concentration to try and reduce formaldehyde exposure and they succeeded all right, but in doing so a couple of our measurements surpassed the TLV-STEL (250 ppm) for methanol and they went back to their original recipe. So if you are going to do monitoring, don't forget to test for methanol exposure in addition to formaldehyde.

Ethanol would be a better choice over methanol but we can leave that discussion for happy hour.

That pretty much allows as much as 98% formaldehyde in the formulation. Sometimes I wonder what the authors of such SDS documents are thinking. (I know, it's the lawyers who are doing their thinking for them. )
