In my quest to find the formula make up of Cachet AB 55, I found the list of chemicals used in a Precaustions that came with the package. They are as followed along with some notes.
Sodium Sulfite - common developing agent in developers; can prevent the formation of many undesirable by products during development. Darkroom Cookbook page 195.
Hydroquinone - builds density in combination with other developers. Darkroom Cookbook Page 182
1-Phenyl-3-Pyrazolidone - is actually Phenidone. used alone in sulfide solutions, it is very fast but extremely soft working and is only capable of producing negatives of low contrast. In combination with hydroquinone it produces developers with superadditivity that are even more efficient than MQ developers. Phenidone-based developers keeps better than those based on metal. You can read more in Darkroom Cookbook page186. Page 21, 1st paragraph optimum amount of Phenidone to hydroquinone is 7%
Sodium Tetraborate is Borax. Its a mild accelerator. From what I have read this can be used in Solution B solely. Darkroom Cookbook page 195 but see page 178
All information comings from the Darkroom Cookbook 3rd Edition.
As mentioned, I am not a chemist and would like to know where to begin in terms of amount of chemicals to be used in Solution A and Solution B. The only thing I know for sure is that Borax can be used for Solution B only. If anyone can provide a starting point or a solution it would be greatly appreciated.
Thank you for your time and assistance.
