The test substance was weighed into a tared glass beaker on a suitable precision balance and the vehicle added (weight:volume).
Afterwards, the test substance preparation was warmed up to 50°C. The formulations were prepared using a suitable homogenizer. The test substance preparation was kept at room temperature for cooling and was administered when a temperature between 20°C and 30°C is reached. The temperature was measured before treatment with a thermometer and reached 24°C and 25.8°C. - No. of animals per sex per dose:

All animals were killed at the end of the observation period by carbon dioxide asphyxiation and discarded after macroscopic examinations were performed. No organs or tissues were retained.
- Frequency of observations and weighing:
- Mortality / Viability and Clinical Signs: Daily during the acclimatization period, during the first 30 minutes and at approximately 1, 2, 3 and 5 hours after administration on test day 1 and twice daily during days 2-15. All abnormalities were recorded.

- Interpretation of results:
- other: CLP criteria not met
- Conclusions:
- Under the study conditions, the acute oral LD50 of the test substance in rats was determined to be >2000 mg/kg bw.
- Executive summary:
A study was conducted to determine the acute oral toxicity of the read substance, 'di-C16-18 and C18-unsatd. AAEMIM-MS', according to OECD Guideline 423 (Acute Toxic Class Method), in compliance with GLP. Three FemaleHanRcc: WIST(SPF)rats were administered the test substance by oral gavage at a dose of 2000 mg/kg bw. Following administration, the animals were observed for 14 d and mortality, clinical signs and body weights were recorded daily. At the end of this period, rats were examined for macroscopic and microscopic abnormalities. There was no mortality in this study. No evidence of systemic toxicity was noted during the study period. No toxicologically significant effects on bodyweight were recorded during the study period and no abnormalities were seen at necropsy of animals killed at the end of the study. Under the study conditions, the acute oral LD50 of the substance in rats was determined to be >2000 mg/kg bw (Evonik, 2010). Based on the results of the read across study, similar oral LD50 value can be expected for the test substance, ' di-C16 and C18-unsatd. AAEMIM-MS'.

Justification for classification or non-classification
Based on the results of the read across study, the test substance, 'di-C16 and C18-unsatd. AAEMIM-MS', does not warrant classification for acute oral toxicity, according to the EU CLP criteria (Regulation 1272/2008/EC).
