Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: other: EU and CLP classification
Conclusions:
Under the conditions of this test, the test compound did not induced any mortality among the animals at the tested dose level of 5000 mg/kg.
Executive summary:

In an acute dermal toxicity study, 10 rats were given a single dermal dose of heptanal at a dose level of 5000 mg/kg bw and observed for 14 days. No death occured during the course of the study. No clinical signs were reported. LD0 = 5000 mg /kg bw in rats.

Under the conditions of this test, heptanal is therefore not classified according to EU and GHS classifications.
