Applicant's summary and conclusion

Interpretation of results:
other: not toxic
Remarks:
Criteria used for interpretation of results: EU
Conclusions:
Après administration jusqu'à la dose maximale de 5000 mg/kg, aucun décès n'est constaté. Quelques troubles respiratoires sont enregistrés aux plus fortes doses mais les animaux retrouvent leur état antérieur après 6 heures sans qu'aucune variation de poids n'ait été constatée.
DL50 (orl, rat) > 5000 mg/kg
