Pyrocat MC working solution (if my calculation is correct) has:
metol..............0.025g/L
ascorbic acid....0.04g/L
pyrocatechin....0.5g/L
So your developer has quite high metol & AA ,no need for high pH?
can be simple mixed in one part. I'm starting with Pyrocat-PC proportionThat's just Part A
Then add Part B the alkali
Can someone explain "DEA" and "MEA"? I'm only familiar with TEA / Triethanolamine.
MEA will not yield a very high pH and in small amounts offers no advantage over sodium hydroxide or sodium carbonate.
It's unclear just what you are attempting to do which makes it hard to offer any specific advice. You can dissolve the developing agents in propylene glycol. Then take a small amount of this solution and add it to either a carbonate or hydroxide solution to make a working developer.
