Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
7.05 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:
528.9 mg/m³
Explanation for the modification of the dose descriptor starting point:
NOAECcorr = NOAELoral*(1/0.38 m³/kg bw/day)*(ABSoral-rat/ABSinh-human)*(6.7 m³ (8h)/10 m³ (8h)) = 300 mg/kg bw/day*(1/0.38 m³/kg bw/day)*0.67 = 528.9 mg/m³.
AF for dose response relationship:
1
Justification:
DNEL is based on a NOAEL
AF for differences in duration of exposure:
6
Justification:
Default AF
AF for interspecies differences (allometric scaling):
1
Justification:

Workers - Hazard via dermal route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
10 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:
3 000 mg/kg bw/day
Explanation for the modification of the dose descriptor starting point:
NOAELcorr = NOAELoral*(ABSoral-rat/ABSdermal-human) = (300 mg/kg bw/day)*(1/0.1) = 3000 mg/kg bw/day. It is assumed that the dermal absorption rate is 10% of that of the oral absorption.
