Test animals
- Species:
- rat
- Strain:
- Sprague-Dawley
- Sex:
- male/female
Administration / exposure
- Type of coverage:
- open
- Vehicle:
- DMSO
- Details on dermal exposure:
- Animals from treated group received by topical application, under non occlusive porous gauze dressing (50 mm x 50 mm non-woven swab of 4-layer patch from MEDISTOCK) secured in position with a strip of surgical adhesive tape (50 mm wides hypoallergenic microporeTM adhesive tape from 3M), an effective dose of 2000 mg/kg body weight administered under a volume of 10 mL/kg body weight, during 24 hours. After 24-hour exposure period, the gauze dressings were removed and the
treated area was rinse with distilled water. - Duration of exposure:
- 24 hours
- Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 5/sex/dose

Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred during the study.
- Clinical signs:
- other: No systemic clinical sign related to the administration of the test item was observed. Erythema and oedema was noted on the treated areas in all treated animals (10/10) at 48 hours post dose. These reactions were totally reversible between days 3 and 8. D
- Gross pathology:
- The macroscopic examination of the animals at the end of the study did not reveal treatment-related changes.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The LD50 of the test item SOLVENT RED 24 MIX is higher than 2000 mg/ kg body weight by dermal route in the rat.
The test item SOLVENT RED 24 MIX does not have to be classified in accordance with the Regulation EC No. 1272/2008 on classification, labelling and packaging of substances and mixtures. No signal word or hazard statement is required.
