Genetic toxicity: in vivo
Administrative data
- Endpoint:
- genetic toxicity in vivo, other
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Justification for type of information:
- No in vivo studies are available, however the absence of systemic exposure to the substance and the lack of genotoxicity of the hydrogen and sulphate ions means that no genotoxicity is predicted and testing is not required. The corrosive nature of the substance also means that testing cannot be justified on animal welfare grounds (the in vivo testing of corrosive substances is discouraged by the REACH Regulation for scientific reasons and on animal welfare grounds).
