Xtol pretty clearly does not contain Hydroquinone. Ascorbic acid is
itself a reducing agent. I find very little about it in the literature
available to me. It was apparently used mostly for research work until
recently. Xtol seems to be Phenidone and Iso-Ascorbic acid. Ilford Ilfosol
seems to be an MQ developer with Ascorbic acid added. It would be
interesting to know more about the function of the Acorbic acid in both
devlopers.
