PHENOTHIAZINE G4 is a polymerization inhibitor solution. It is produced by dissolving solid phenothiazine in a high-boiling-point solvent. Because it is in liquid form, it can be easily added to liquids in which phenothiazine may have difficulty dissolving. In terms of performance, it can be expected to provide the same polymerization inhibiting effect as phenothiazine.
