Lou:

I recommend looking at the MSDS sheet.  It should give you some information on sympoms.
It may be likely that the diethylene glycol monobutyl ether, which is an irritant, is causing the problems.  Glycol ethers are known to cause reproductive toxicity too.  Maybe you should check into the ventilation.

Subject:        [TN] Saponifiers and safety

TechNetters, for about 1 month, we have been using a new saponfier in our automated cleaner.  Composition is uncertain, the Material Safety Data sheet says it is less than 60% diethylene glycol butyl ether and less than 35% monoethanolamine.  The old saponifier was 24.8% "glycol ether category" and less than 40% monothanolamine, with some amount of tetrahydrofurfuryl alcohol.  Approximately 8 people (of perhaps 16 in the work area) have experienced a sore throat and irritation with the new material.  Can anyone comment?  I wonder if this glycol ether is something especially troublesome.  Many thanks...Lou Hart
