Description of key information
no studies available.
to estimate the toxicokinetics properties of the substance, physicochemical parameters are utilised (Regulation (EC) No 1907/2006, 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

Based on these parameters, the bioaccumulation potential is judged as low (log POW< 4)
The substance is a solid with a high boiling point and a low Vapour pressure, the particle size is large,
which leads to a low absorption rate by inhalation.
For dermal and oral Absorption rate 100 % are assumed by default.
