Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
44.08 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):
40
Modified dose descriptor starting point:
NOAEC
Value:
1 763.2 mg/m³
Explanation for the modification of the dose descriptor starting point:

No dose descriptor for inhalative exposure available. A route-to-route extrapolation from an oral subchronic study was therefore necessary. Rational for selection of dose descriptor: there were no systemic effects at the limit dose (1000 mg/kg bw/day), the NOAEL was 1000 mg/kg bw/day. Conversion oral rat to inhalation human: NOAEL /0.38 m³/kg (respiratory volume rat) x 6.7 m³ (respiratory volume human (8h)/10 m³ (respiratory volume worker (8h).

AF for differences in duration of exposure:
2
AF for interspecies differences (allometric scaling):
4
AF for intraspecies differences:
5
Acute/short term exposure
Hazard assessment conclusion:

Workers - Hazard via dermal route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
25 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):
40
Modified dose descriptor starting point:
NOAEL
Value:
1 000 mg/kg bw/day
Explanation for the modification of the dose descriptor starting point:

No dose descriptor for dermal exposure available. A route-to-route extrapolation from an oral subchronic study was therefore necessary, assuming 100% dermal absorption rate (worst case). Rational for selection of dose descriptor: there were no systemic effects at the limit dose (1000 mg/kg bw/day), the NOAEL was 1000 mg/kg bw/day.

General Population - Hazard via inhalation route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
10.87 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):
80
Modified dose descriptor starting point:
NOAEC
Value:
869.6 mg/m³
Explanation for the modification of the dose descriptor starting point:

No dose descriptor for inhalative exposure available. A route-to-route extrapolation from an oral subchronic study was therefore necessary. Rational for selection of dose descriptor: there were no systemic effects at the limit dose (1000 mg/kg bw/day), the NOAEL was 1000 mg/kg bw/day. Conversion oral rat to inhalation human: oral NOAEL x 1 /1.15 m³/kg/d (respiratory volume rat in 24h).
