1. Identification of relevant dose descriptor
In an in-utero and life time study performed in rat , the substance did not cause mortalities, toxicity to reproduction and development or any adverse effects. The NOAEL is considered to be 32.42 mg/kg bw/d.
2. Mode of action
No non-threshold mode of action is associated with the test substance. In particular, the test substance has no genotoxic potential.
3. Application of assessment factors
Allometric scaling: rat to human = 4
Remaining uncertainties: interspecies differences = 2.5
Intraspecies factor: worker = 5, general population = 10
Exposure duration chronic to chronic: 1
Quality of data base: 1
Dose response: 1
4. Daily exposure
Worker: exposed for 8h
General population: exposed for 24h
Calculation of DNEL bases upon Guidance Document on Dermal Absorption, European Commission, 2004 and Guidance on information requirements and chemical safety assessment Chapter R.8: Characterisation of dose [concentration]-response for human health, may 2008
