Me again ...
Because the quantities of phenidone required in developers are very low and
difficult to measure, many dissolve it in either alcohol, propylene glycol or
glycerin at a low concentration.
After googling, it looks like propylene glycol and glycerin allow a better
shelf life of the solution, maybe with a slight advantage to glycerin but at
the cost of being less agreable to use due to its high viscosity.
Do some of you already tried both products ?
What is your preferrence and why ?
Thanks in advance,
