Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information

Due to low water solubility, high adsorption potential to organic carbon and its high density, phenothiazine is considered to be bound mainly to sediment in the aquatic environment. No further data are available for this compartment.

The most relevant abiotic degradation is by photolysis in air.

Phenothiazine is a very potent radical scavenger. The rate constant for the vapour-phase reaction of phenothiazine with photochemically produced hydroxyl radicals has been estimated using the AOPWIN v.192 software as 1.8X10 -10 cu cm/molecule-sec at 25 deg C. This corresponds to an atmospheric half-life of about 0.73 hours at an atmospheric concentration of 1.5X10 +6 hydroxyl radicals per cu cm.
