MAXIMUM DOSE VOLUME APPLIED: 20 mL/kg bw.
DOSAGE PREPARATION:
The test item was suspended in the vehicle. - Doses:
- 5000 mg/kg bw
- No. of animals per sex per dose:
- 3 female rats
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: observations were performed before and immediately, 5, 15, 30 and 60 minutes, as well as 3, 6 and 24 hours after administration. During the follow-up period of two weeks, clinical signs were observed at least once a day until all symptoms subsided, thereafter each working day.
Individual body weights were recorded before administration of the test item and thereafter in weekly intervals up to the end of the study. Changes in weight were calculated and recorded.
- Necropsy of survivors performed: yes, at the end of the experiments, all animals were sacrificed, dissected and inspected macroscopically. - Statistics:
- No statistical analysis could be performed (the method used is not intended to allow a calculation of a precise LD50 value).
- Preliminary study:

- other body weight observations
- Gross pathology:
- No pathological changes were observed at necropsy.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- LD50 (female rats) > 5000 mg/kg bw
According to the Regulation (EC) No 1272/2008 and subsequent adaptations, the substance is not acutely toxic via the oral route.

Additional information
Acute oral toxicity:
One acute oral toxicity study with titanium, iron and aluminium pseudobrookite and rutile is available, which is a GLP study conducted according to OECD guideline 423. The acute oral toxicity was tested by performing a limit test in female Crl:CD (SD) rats. Three rats received a single oral gavage at a dose of 5000 mg/kg bw. All animals were observed daily for a period of 14 days. Individual body weights were recorded before administration and thereafter in weekly intervals. At the end of the study all animals were sacrificed, dissected and inspected macroscopically. No mortality, clinical signs, changes in body weight or pathological changes were observed. The LD50 for acute oral toxicity was set greater than 5000 mg/kg bw.
Justification for classification or non-classification
Acute oral toxicity:
The available guideline-conform study conducted under GLP indicate that test item is not acutely toxic via the oral route. Thus, according to Regulation (EC) No 1272/2008 and subsequent regulations, no classification or labelling is required.
