Product Description
Because metol is relatively toxic and can cause skin sensitisation, modern commercial developers often use phenidone or dimezone S (4-hydroxymethyl-4-methyl-1-phenyl-3-pyrazolidone) instead.
This developing agent is therefore great for student or home use as it is ""safer"" to use. Ilford Multigrade and PQ Developers contain Dimezone S.
Dimezone-S keeps better in aqueous solution
.
