Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

DNEL related information
- DNEL derivation method:
- ECHA REACH Guidance
- Overall assessment factor (AF):
- 100
- Dose descriptor starting point:
- NOAEL
- Value:
- 4 683 mg/kg bw/day
- Modified dose descriptor starting point:
- NOAEL
- Value:
- 4 683 mg/kg bw/day
- Explanation for the modification of the dose descriptor starting point:
Route to route extrapolation was used as there is no dermal absorption information to estimate the systemic dose from the dermal dose, then the oral NOAEL was used as starting point. The dose descriptor starting point is obtained by conversion of the oral NOAEL to a dermal NOAEL considering a similar (very low) absorption by both oral and dermal route. Thereby, the corrected starting dermal NOAEL is equal to the oral NOAEL = 4683 mg/kg bw.
