Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- These results indicate that the test item, cC6O4 ammonium salt, has no toxic effect on the rat following dermal exposure over a 24 hour period at a level of 2000 mg/kg. The lack of mortality demonstrates the LD50 to be greater than 2000 mg/kg, thus there results no classification according to the European CLP regulation.
- Executive summary:
The acute toxicity of cC6O4 ammonium salt was investigated following administration of a single dermal dose to the rat. No mortality occurred following dosing and no significant clinical signs were observed. These results indicate that the test item, cC6O4 ammonium salt, has no toxic effect on the rat following dermal exposure over a 24 hour period at a level of 2000 mg/kg. The lack of mortality demonstrates the LD50 to be greater than 2000 mg/kg. European Directives concerning the classification, packaging and labelling of dangerous substances and preparations (Regulation (EC) no. 1907/2006, 67/548/EEC and subsequent revisions) would indicate the following:
Classification : Not required
Signal word : None indicated
Hazard statement : None indicated
