Applicant's summary and conclusion

Interpretation of results:
not classified
Migrated information Criteria used for interpretation of results: EU
- By oral route in the condition of the test, the substance is not toxic. According to the criteria given in Annex I of Regulation EC/1272/2008, the substance Acacia mearnsi extract should not be classified as hazadous for acute oral toxicity.
Executive summary:

The Acute Oral Toxicity Test-Fixed Dose for rats was conducted to study the potential toxic effects of ACQUAPOL C1. The product was used in pure form (liquid) and administrated orally to rats that were 8 - 12 weeks old, at the dose of 2000 mg/kg of live weight in the pre-test, and at the dose of 2000 mg/kg of live weight for the final test. The animals were observed for time to death, behavioral changes, clinical signs and macroscopic anatomopathological findings. The final test was conducted with a dose of 2000 mg/kg of live weight, in which the animals do not present clinical signs of toxicity, which allows the product ACQUAPOL C1 to be classified in toxicological class V (Non-toxic) according to the classification table for acute toxicological risk according to GHS-OECD by oral route. Moreover, according to the criteria given in Annex I of Regulation EC/1272/2008, the substance Acacia mearnsi extract should not be classified as hazadous for acute oral toxicity in the testing conditions (LD50 > 2000 mg/kg of live weight).
