IIRC, the main component was TEA. But I only used it for screen and offset printing.

BTW they are using THE OLD classification hazard symbols. They should have been replaced since June 2015 according GHS.

TEA = tri- Ethanol Amine, e.g. also used in PC-TEA from Pat Gainer.

That makes it 36.3% TEA. The print industry version probably had even more of it (or was a higher concentration all around), as I remember it congealing in our store room well above freezing point.

OK Well I will start with Microphen as that was recommended by the seller of the oudated Orwo. I have two liters of Microphen in my darkroom right now.
