Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute LD50 of the test material to male and female mice was greater than 8000 mg/kg body weight when administered by the oral route of exposure.
- Executive summary:
In an acute oral toxicity study, 4 groups of 10 mice (males and females) were given a single oral dose of LRG-1393 at 1000, 2000, 4000 and 8000 mg/kg b.w.
There were no deaths during the study at 24 hours after exposure or at 10 days after exposure.
Oral LD50 > 8000 mg/kg b.w.
Under the test conditions, LRG-1393 is not classified according to the annex VI of the Regulation (EC) No. 1272/2008 (CLP) and of the Directive 67/548/EEC.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
