Under the conditions of this study the median lethal dose of Stearylacrylate, Synative MM SA, Stearyl 1618 after oral administration was found to be greater than 2000 mg/kg bw in rats.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of this study the median lethal dose of the test substance after oral administration was found to be greater than 2000 mg/kg bw in rats.
- Executive summary:
In an acute oral toxicity study performed according to the Acute Toxic Class method, 2000 mg/kg bw of the undiluted test item were administered to two test grooups of three fasted Wistar rats by gavage.
The following test substance-related clinical observations were recorded:
2000 mg/kg:
- No mortality occured.
- No clinical signs were observed.
- The mean body weight of the surviving animals incresed within the normal range throughout the study period. Except one animal of the first test group, which showed stagnation of body weight during the second post-exposure week.
- There were no macroscopic pathological findings in the surviving animals sacrificed at the end of the observation period.
The acute oral LD50 was calculated to be > 2000 mg/kg bw.
