Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
1.2 mg/m³
Most sensitive endpoint:
repeated dose toxicity
Route of original study:
Oral
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
75
Modified dose descriptor starting point:
NOAEC
Value:
88 mg/m³
Explanation for the modification of the dose descriptor starting point:
No inhalation study available. Thus, extrapolation from oral study wtih a NOAEL of 50 mg/kg bw/d with respect to repeated dose toxicity. A NOAEL of 50 mg/kg bw/day was established in a 28-day study based on changes in hematology parameters and slightly increased mean kidney and liver weights in males and females treated with 250 mg/kg bw/day.
AF for dose response relationship:
1
AF for differences in duration of exposure:
6
AF for interspecies differences (allometric scaling):
1
AF for other interspecies differences:
2.5
AF for intraspecies differences:
5
AF for the quality of the whole database:
1
AF for remaining uncertainties:
1
Acute/short term exposure
Hazard assessment conclusion:
hazard unknown (no further information necessary)
DNEL related information

Local effects

Long term exposure

Workers - Hazard via dermal route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
0.2 mg/kg bw/day
Most sensitive endpoint:
repeated dose toxicity
Route of original study:
Oral
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
300
Modified dose descriptor starting point:
NOAEL
Value:
50 mg/kg bw/day
Explanation for the modification of the dose descriptor starting point:
No dermal repeated dose studies available. Absorption by dermal route is by default considered identical to absorption from oral route.
AF for dose response relationship:
1
AF for differences in duration of exposure:
6
AF for interspecies differences (allometric scaling):
