Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The oral LD50 value of Titanium(4+) ethanolate in Wistar rats was established to exceed 2000 mg/kg body weight. This study was conducted according to the OECD 423 method and in compliance with GLP.
- Executive summary:
The objective of this study was to assess the toxicity of the titanium(4 +) ethanolate when administered in a single oral dose (2000 mg/kg bw) to female rats. The oral route was selected as it is a possible route of human exposure during manufacture, handling or use of the test substance. No mortalities was observed at the tested dose level. According to the OECD 423 test guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight.
The study is considered reliable without restrictions since the study is carried out based on the OECD No. 423 guideline and in compliance with principles of Good Laboratory Paractice (GLP).
Based on these results, Titanium(4 +) ethanolate does not have to be classified and has no obligatory labeling requirement for acute oral toxicity according to CLP Regulation 1272/2008 and Directive 67/548/EEC.
