Interpretation of results:

not classified

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

LD50 was estimated to be 4103.573730469mg/kgbw when rat were treated with undecenal orally.

Executive summary:

Acute oral toxicity was estimated in rats by using undecenal . 50 % mortality was observed in treated rats. Therefore, LD50 was estimated to be 4103.573730469mg/kgbw when rat were treated with undecenal orally.
