Applicant's summary and conclusion

Interpretation of results:
other: Not classified
Conclusions:
The lethal concentration (LD50) value for acute dermal toxicity test was considered to be >5000 mg/kg bw,when rabbits were treated with test chemical Methyl nonyl ketone via dermal route.
Executive summary:

Acute dermal toxicity study was performed in rabbits using test chemical Methyl nonyl ketone (CAS no.: 112 -12 -9, E.C. no.: 203 -937 -5). 4male and 4female rabbits were treated at a dose concentration of 5000mg/kg bw. Animals were further observed for clinical signs of toxicity and mortality. No mortality was observed at dose 5000 mg/kg bw. Hence, the LD50 value was considered to be >5000mg/kg bw,when rabbits were treated with test chemical Methyl nonyl ketone via dermal route. The test chemical can be considered as "Not classified" according to the CLP.
