Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Workers - Hazard via inhalation route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
5.1 mg/m³
Most sensitive endpoint:
repeated dose toxicity
Route of original study:
Oral
DNEL related information
DNEL derivation method:
other: ECETOC guidance (Technical Report No. 110, October 2010)
Overall assessment factor (AF):
36
Modified dose descriptor starting point:
NOAEC
Value:
183.4 mg/m³
Explanation for the modification of the dose descriptor starting point:
there is no evidence that route-to-route extrapolation cannot be applied. Kinetics (metabolism, distribution and excretion) are considered to be similar for oral and inhalation intake in the absence of evidence of the opposite.

1
Justification:
NOAEL in reliable subacute oral toxicity study in rat
AF for differences in duration of exposure:
3
Justification:
Assuming chronic exposure of the worker
AF for interspecies differences (allometric scaling):
1
Justification:
No correction for caloric demand for inhalation
AF for other interspecies differences:
1
Justification:
According to ECETOC guidance
AF for intraspecies differences:
