Applicant's summary and conclusion

Interpretation of results:
Category 5 based on GHS criteria
Conclusions:
LD50 was considered to be 2600 mg/kg bw when rats was treated with Propionic acid orally.
Executive summary:

In a acute oral toxicity study,rats was treated with Propionic acid in the concentration of 2600 mg/kg bw orally. 50 % mortality was observed in treated rats at 2600 mg/kg bw. Therefore, LD50 was considered to be2600mg/kg bw when rat were treated with Propionic acid orally.
