Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Explanation for the modification of the dose descriptor starting point:
Most sensitive endpoint: the NOAEL for a combined repeated dose oral toxicity study with the reproduction/developmental toxicity screening test was considered to be 1000 mg/kg/day for males and females.
The NOAEL for reproductive/developmental toxicity was considered to be 1000 mg/kg/bw.
--> correct to worker, 8h inhalation:
NOAEC = 1000 * (1/ 0.38) * (6.7 / 10) = 1763.2 mg/m3
--> in the absence of information on gastro-intestinal absorption an assessment factor of 2, default value for oral-to-inhalation extrapolation has to be applied:
NOAEC = 1763.2 / 2 = 881.6 mg/m3

- Value:

- Explanation for the modification of the dose descriptor starting point:
Most sensitive endpoint: the NOAEL for a combined repeated dose oral toxicity study with the reproduction/developmental toxicity screening test was considered to be 1000 mg/kg/day for males and females.
The NOAEL for reproductive/developmental toxicity was considered to be 1000 mg/kg/bw for pubs.
--> correct to general population, 24h inhalation:
NOAEC = NOAEL (mg/kg bw/d) * (1/1.15 m3/kg bw)
NOAEC = 1000 * (1/1.15) = 869.6 mg/m3
