Administrative data
Link to relevant study record(s)
Description of key information
No study available. The relevant physico-chemical data are assessed in regard of toxicokinetics. (Assessment of the toxicokinetic behaviour of the substance to the extent that can be derived from the relevant available information, EC 2006/1907, Annex VII, 8.8.1)
Key value for chemical safety assessment
- Bioaccumulation potential:
- low bioaccumulation potential
- Absorption rate - oral (%):
- 100
- Absorption rate - dermal (%):
- 100
- Absorption rate - inhalation (%):
- 10
Additional information
There is one study available for the structural analogue 1H-Benzotriazole on the metabolism. However, this study does not give sufficient information for this endpoint and is regarded as supporting study.

Based on these parameters, the bioaccumulation potential is judged as low (log POW< 4).
The pure substance is a solid with a low vapour pressure. It is manufactured and marketed as an aqueous solution. Based on this information the inhalative absorption is assumed to be 10 %. For dermal and oral Absorption rate 100 % are assumed by default.
