Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred.
- Clinical signs:
- other: Blue and/or yellow staining of the treated site was observed in all animals from Day 2 up to Day 15.
- Gross pathology:
- Yellow staining of the treatment site was observed during the external examination performed on all animals at termination of the study. In two
single occasions (animal nos. A0674004 and A0674005), also blue staining was noted. No internal abnormalities were seen at necropsy examination.
Applicant's summary and conclusion
- Interpretation of results:
- study cannot be used for classification
- Remarks:
- Migrated information
- Conclusions:
- These results indicate that the test item, Disperse Blue ANT, has no toxic effect on the rat following dermal exposure over a 24 hour period at a
level of 2000 mg/kg body weight. The lack of mortality demonstrates the LD50 to be greater than 2000 mg/kg body weight. - Executive summary:
The acute toxicity of Disperse Blue ANT was investigated following dermal administration of a single dose to the rat followed by a 14-day observation period. A single dose of 2000 mg/kg body weight was administered to a group of 5 male and 5 female animals for 24 hours. After 14 days all animals were killed and subjected to necropsy examination. No mortality occurred and no signs of toxicity were observed in male or female animals during the observation period. Staining of the treatment site was seen during the entire observation period of the study starting from the day after dosing. The body weight changes observed during the study were within the expected range for this species and age of animals. Staining of the treatment site was found in all animals at termination of the study. No internal abnormalities were seen. These results indicate that the test item, Disperse Blue ANT, has no toxic effect on the rat following dermal exposure over a 24 hour period at a level of 2000 mg/kg body weight. The lack of mortality demonstrates the LD50 to be greater than 2000 mg/kg body weight.
