"According to the package it contains Sodium pyrosulphite (whatever salt that is!), hydrochinone and phenidone."Originally Posted by rjr
Sodium pyrosulphite Na2 S2 05 is also called sodium disulphite (bisulfite) or sodium metabisulphite (metabisulfite).
AFAIK the first Phenidone/Hydroquinone "Universal Developer" formulation was published by Ilford. It does not contain either Glycin or Metol and thus is not similar to Ansco 130. I started compounding it in the 1970's and used it for many years as a paper developer (I added benzotriazole). The results were very similar to Kodak Dektol, but with a longer shelf life for the concentrated stock solution.
