I guess you could try it and see for yourself. All you need do is put a couple of grams of Metol in 100 ml of glycerol and see how long it takes to dissolve at room temperature. All we really want is a solution containing 2.5 grams Metol and 4 grams ascorbic acid in 100 or so ml that is in turn soluble in propylene glycol. Water doesn't work. Glycerol does.
