Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Justification for type of information:
Data waiving
Reason: The results of the chemical safety assessment do not indicate the need to further investigate the effects of the substance and/or relevant degradation products on sediment organisms.
Justification:In accordance with column 2 of REACH Annex X, long-term toxicity testing shall be proposed by the registrant if the results of the chemical safety assessment indicates the need to investigate further the effects of the substance and/or relevant degradation products on sediment organisms. Due to the relatively high PNEC derived for sediment organisms, based on conservative assumptions and derived from the PNECaquatic using the Equilibrium Partitioning Method (EPM), along with the conclusion of no aquatic toxicity classification warranted for tungsten oxide, further sediment long-term toxicity investigation is not needed.
