Powder developers tend to be Metol based and have a shorter tray life than developers using Phenidone or Dimezone instead.

Powdered Dektol/D72 is an MQ developer so uses Metol while Liquid Dektol (Polymax in some countries) is a PQ developer.

The big advantage of PQ based print developers is they can be sold as concentrates, have a much longer shelf life, and are more economic.
