- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information Criteria used for interpretation of results: not specified
- Conclusions:
- Not sensitising
- Executive summary:
The skin sensitisation was determined using the OECD 406 and EU B6 test methods. Details are not available, but the data has been reviewed by a suitable EU Competent Authority and provided by ECHA. The test substance is not sensitising.
Reference
Signs of irritation during induction: Not specified
Evidence of sensitisation of each challenge concentration: No evidence of delayed contact hypersensitivity seen in any of the test 20 animals.
Localised dermal reactions were observed (restricted to a small area of the challenge site).
Other observations: The dermal reaction seen in the test animals were similar to those seen in the controls.
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
- Migrated from Short description of key information:
Skin Sensitisation: Not sensitising (Guinea Pig) [Key study & supporting study].
Justification for selection of skin sensitisation endpoint:
Data has been provided by ECHA from a previous notification. The data has been reviewed by a suitable Competent Authority and adjudged to be suitable for registration.
Justification for classification or non-classification
The substance is not classified under CLP as it does not fill the requirements for skin sensitising classification.
