Description of key information

Single application of 10000 mg test substance per kg bw did not cause lethality in female Wistar-rats during the 14 day observation period, resulting in a LD50 > 10000 mg/kg bw.


The Test item (<90% Pigment Red 112) did not cause any mortality or significant clinical signs or necropsy findings after single dermal application to male rats at 5000 mg/kg bw in a OECD guideline compliant study. The LD50 (male rat) was greater than 5000 mg/kg body weight.

other: - 5-6 hours after application some clinical signs of toxicity (high legs) were observed - no clinical symptoms were observed in any animal 24 h or later after test item application - faeces was red-coloured
Gross pathology:
- animals killed at the end of the observation period showed no macroscopically visible changes
Interpretation of results:

Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Single application of 10000 mg test substance per kg bw did not cause lethality in female Wistar-rats during the 14 day observation period, resulting in a LD50 > 10000 mg/kg bw.
Executive summary:

Female Wistar-rats were subjected to test acute oral toxicity. The test substance was administered by gavage at a dose of 10000 mg/kg bw (12.5% suspension in sesame oil). No animal died during the 14 day observation period, resulting in a LD50 >10000 mg/kg bw.
