Applicant's summary and conclusion

Conclusions:
The fetotoxicity LOEL value (Low observed effect level) of 3-oxoglutaric acid in rat by the oral route was observed at a dose concentration of 202.7mg/kg bw/day.This indicates that 3-oxoglutaric acid shall not exhibit toxic effect to rat by the oral route below the above mentioned dose.
