Found it on Sigma-Aldritch's site as a photographic chemical
"N-Ethyl-N-(2-hydroxyethyl)-p-phenylenediamine sulfate salt monohydrate"
Found some info on it here - http://www.chemicalbook.com/ProductChemicalPropertiesCB4300409_EN.htm
Can anybody shed some light on this?
Given it's a related ppd.. I assume its a newer process/formula for colour?
It's rather relatively inexpensive on Sigma Aldritch's site compared to the price they sell other stuff for.
