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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Relevant PNEC values do not include PNECsoil and PNECoral.
A value for PNECsoil appears not to be relevant since the substance is characterised by a very low vapour pressure, very low water solubility and further it is known to be subject to photolysis.
Further, values for PNECoral mammals and birds are considered not to be relevant based on the log Kow which is measured to be 3.78. The bioaccumulation threshold value of log Kow 4.5 is not reached.
Conclusion on classification
Based on the negative results of the ready biodegradability test, the substance phenothiazine is regarded as persistent. Toxicity levels in the aquatic compartment were found to be lowest in daphnia (EC50 short term: 0.154 mg/L), whereas an algae test did not reveal any influence on the growth. In between is the toxicity for fish with an lethal concentration 50 of 0.579 mg/L and higher than the daphnia EC50 value.
As the Substance does not fulfil the „B“ criterion, the most relevant hazard for the environment is assumed due to the „T“ criterion and the persistence of phenothiazine.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
