Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Toxicity to microorganisms
Administrative data
Link to relevant study record(s)
- Endpoint:
- activated sludge respiration inhibition testing
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is highly insoluble in water, hence indicating that aquatic toxicity is unlikely to occur

Description of key information
According to Column 2 of REACH Annex VIII of Regulation (EC) No 1907/2006, STP toxicity testing (activated sludge respiratory inhibition testing) does not need to be conducted if there is no emission to a sewage treatment plant or there are mitigating factors, indicating that microbial toxicity is unlikely to occur, for instance the substance is highly insoluble in water (limitation of exposure). Due to the inherent properties of titanium diboride (practically insoluble in water inorganic substance and not biodegradable, not bioavailable, does not cross biological membranes) performance of a study on toxicity to activated sludge is not required
Key value for chemical safety assessment
Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
