Acute toxicity: via oral route

Link to relevant study records
Reference
Endpoint:
acute toxicity: oral
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Reason / purpose for cross-reference:
read-across source
Reason / purpose for cross-reference:
read-across: supporting information
Preliminary study:
There were no daeths or clinical signs of toxicity. Based on this information, a dose level of 2000 mg/kg body weight was selected for the main study.
Key result
Sex:
male/female
Dose descriptor:
LD50
Effect level:
> 2 000 mg/kg bw
Based on:
test mat.
Mortality:
There were no deaths
Clinical signs:
other: No signs of systemic toxicity were noted during the study.
Gross pathology:
No abnormalities were noted at necropsy.
Other findings:
no
Interpretation of results:
GHS criteria not met
Conclusions:
The acute oral median lethal dose of titanium dioxide was found to be greater than 2000 mg/kg body weight. Based on these results, it is predicted that also no symbol and risk phrase are required for the structural analogue Titanium oxide (Ti3O5) according to EU labelling regulations.
