Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The acute oral median lethal dose (LD50) of the test item in the female Wistar strain rat was estimated to be at least 5000 mg/kg body weight (Globally Harmonized Classification System - Unclassified).
According to the findings in this study GUERBETALKOHOL does not meet the criteria for classification according to Regulation (EC) No. 1272/2008 of the European Parliament and of the Council of 16 December 2008.
Executive summary:

The study was performed to assess the acute oral toxicity of the test item in the Wistar strain rat.

- Methods

A group of three fasted females was treated with the test item at a dose level of 300 mg/kg body weight. Based on the results from this dose level, further groups of fasted females were treated at a dose level of 2000 mg/kg body weight. Dosing was performed sequentially.

The test item was administered orally as a suspension in arachis oil BP. Clinical signs and body weight development were monitored during the study. All animals were subjected to gross necropsy.

- Results

Mortality. There were no deaths.

Clinical Observations. There were no signs of systemic toxicity.

Body Weight. All animals showed expected gains in body weight.

Necropsy. No abnormalities were noted at necropsy.
