Results and discussion
Test results
- Key result
- Sex:
- male
- Genotoxicity:
- negative
- Vehicle controls validity:
- valid
- Additional information on results:
- Although there are no ADME studies, it can be predicted, based on physical chemical considerations and toxicokinetic prediction, that the substance is likely to reach the target tissue, the bone marrow. Based on these results, p-toluic acid is not anticipated to be genotoxic in vivo.
Applicant's summary and conclusion
- Conclusions:
- Although there are no ADME studies, it can be predicted, based on physical chemical considerations and toxicokinetic prediction, that the substance is likely to reach the target tissue, the bone marrow. Based on these results, p-toluic acid is not anticipated to be genotoxic in vivo.
