DEREK evaluation showed alert for skin sensitization.
Applicant's summary and conclusion
- Interpretation of results:
- other: alert
- Remarks:
- Criteria used for interpretation of results: expert judgment
- Conclusions:
- Derek evaluation for the test item showed alerts for skin sensitisation.
- Executive summary:
The alert also includes coverage for hydrazone precursors of hydrazines.
The presence of a skin sensitisation structural alert within a molecule indicates the molecule has the potential to cause skin sensitisation.
Whether or not the molecule will be a skin sensitiser will also depend upon its percutaneos absorption.
Generally, small lipophilic molecules are more readily absorbed into the skin and are therefore more likely to cause sensitisation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
