Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information according to EU GHS or dangerous substance directive Criteria used for interpretation of results: EU
Conclusions:
3-heptanone is not toxic via an dermal exposure according to the EU classification system
Executive summary:

Acute dermal toxicity to rabbits of 3-heptanone was investigated in a single-dose dermal toxicity study. Dosing was performed by exposing the body surface with 3-heptanone retained on the skin with an impermeable plastic film and mortality was observed for 14 days after dosage. Groups of 5 male animals were used per dose. The LD50 for 3-heptanone was above 20 ml/kg bw, corresponding to 16400 mg/kg bw which is above the classification threshold for acute oral toxicity of 2000 mg/kg bw according to Regulation (EC) 1272/2008 or Directive 67/548/EEC.
