Applicant's summary and conclusion

Interpretation of results:
other: not classified according to CLP regulation
Conclusions:
see 7.8.2 Developmental toxicity / teratogenicity. No evidence of LC50 being reached up to maximum practical aersol concentration, which is also well in excess of the saturated vapour concentration.
