Acute Toxicity: oral
Administrative data
- Endpoint:
- acute toxicity: oral
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 26 September 1991 - 31 October 1991
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Justification for type of information:
- Fully adequate for assessment. Conducted according to OECD TG 401 Acute Oral Toxicity, which was removed from the OECD Test Guidelines Programme in 2001, the GLP compliant study is considered reliable according to OECD 420, EU B.1bis (Commission directive 2004/73/EC).

MAXIMUM DOSE VOLUME APPLIED: 2000 mg/kg - Doses:
- A preliminary range finding test with a dose of 2000 mg/kg bw was conducted in two female rats. No pre-terminal deaths were observed in the 14-day study period.

- Necropsy of survivors performed: animals were sacrificed by CO2 asphyxiation after 14 days and gross pathological examinations were performed.
- Other examinations performed: clinical observations (Irwin-Screening Procedure) were examined at time intervals of: 10 minutes; 1 hour; 2 hour; 3.5 hour; 6 hour; 24 hour; and thereafter once daily upt to day 14.
Results and discussion
- Preliminary study:
- A preliminary range finding test with a dose of 2000 mg/kg bw was conducted in two female rats. No pre-terminal deaths were observed.
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No animals died during the course of the study
- Clinical signs:
- Severe clinical signs, such as reduced activity, abnormal gait, abdominal, lateral or squatting position, piloerection, reduced tone and skin turgor, reduced ear reflex, reduced respiratory rate and reduced audition, were observed up to 6 hours post administration. Signs were mainly in males.
- Body weight:
- Weight gains were normal in all animals
- Gross pathology:
- Gross pathological examination at terminal necrospy (day 14) revealed no test article-dependent findings
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- No pre-terminal deaths were observed in the OECD 401 Acute Toxicity study. Thus, the oral LD50 value is >2000 mg/kg bw. There is no evidence of a relevant intrinsic acute oral toxicity requiring classification or substance specific risk mitigation measures (RMM).
- Executive summary:
The acute oral toxicity of TCD-M-acetate was investigated in male and female Wistar rats (n=10). On the basis of preliminary testing results, animals were give a single oral administration of 2000 mg/kg bw TCD-M-acetate. Clinical signs, such as reduced activity, abnormal gait, abdominal, lateral or squatting position, piloerection, reduced tone and skin turgor, reduced ear reflex, reduced respiratory rate and reduced audition were observed up to 6-hours post-administration. No pre-terminal deaths were observed in the study, consequently, an LD50could not be established. In accordance with the requirements of the limit test, the LD50value is considered to be >2000 mg/kg bw.
