- Qualifier:
- according to guideline
- Guideline:
- EU Method B.1 (Acute Toxicity (Oral))
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 423 (Acute Oral toxicity - Acute Toxic Class Method)
- Principles of method if other than guideline:
- The current study was conduced according to a draft version of OECD 423 (1996).
According to the currently valid OECD 423 (2002), the age of the animals used should be between 8 and 12 weeks. However, since this parameter was not explicitly mentioned in the previous version of OECD 423 (1996), the animals of the present study are declared as “young adults”. Nevertheless, based on the initial body weight and the known strain (Wistar) of the rats used, their age can be estimated to be 5 - 8 weeks for males (body weight of 166 - 173 g) and 7 - 11 weeks for females (body weight of 166 - 191 g). Therefore, this discrepancy is considered to be a minor deviation that can be compensated for by further data of the current study and thus, does not compromise the outcome of the study.
Additionally, fixed dose levels, 5, 50, 300 and 2000 mg/kg bw should be applied according to OECD 423 (2002). However, since the previous version of OECD 423 (1996) required fixed doses of 25, 200 and 2000 mg/kg bw, the mid dose tested was 200 mg/kg bw instead of 300 mg/kg bw. - GLP compliance:
- yes
Results and discussion
Applicant's summary and conclusion
- Interpretation of results:
- study cannot be used for classification
- Conclusions:
- Due to the deviaton from the dose level according to OECD 423 this study cannot be used for the classification.
- Executive summary:
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
