Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 5 000 mg/kg bw
- Mortality:

- Clinical signs:
- other: All animals showed raised fur and slightly decreased motor activities from about 4 hours p.a. to 9 days p.a. at the longest. Arched back was observedin animal No. 6 f between one and 4 days p.a. No other adverse effects were noted during observation time.
- Gross pathology:
- No abnormal findings were noted at post mortem examination.

Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information The LD50 (oral) is higher than 5000 mg Austrostab 133 per kg body weight Criteria used for interpretation of results: other: OECD-Guideline 401
- Conclusions:
- The LD50 (oral) is higher than 5000 mg Austrostab 133 per kg body weight.
- Executive summary:
It was the aim of this study to reveal acute toxic effects of AUSTROSTAB 133 after a single oral administration of 5000 mg test substance per kg body weight. AUSTROSTAB 133 is a stabilizer.
Austrostab 133 was administered perorally to 5 male and 5 female Sprague Dawley rats once at a dose of 5000 mg test substance per kg body weight. The test substance was suspended in a 1 % Na-Carboxymethylcellulose aqueous swelling. Methods and investigations performed were in conformance with OECD-Guideline 401.
Results:
Toxic signs in life: Signs of reduced well-being in all animals were slightly decreased motor activities and raised fur. Onset of signs was approximately 4 hours p.a. No other toxic effects were noted during in life observations.
Mortality: All animals survived till the end of the study.
Post Mortem Examination:
At post mortem examination 14 days after administration no lesions were detected.
LD50 (oral):
The LD50 (oral) is higher than 5000 mg Austrostab 133 per kg body weight.
These results can be assigned to lead silicate since a read across based on a grouping of substances (Pb substances) is applied.
