- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of the test, the undiluted test material (20% in liquid paraffin), produced a 0% sensitisation rate and was classified as a non-sensitizer to guinea pig skin.
- Executive summary:
The sensitization potential of the undiluted test material (20% in liquid paraffin) was assessed in a GLP-conform study according to OECD 406 and Commission Directive 96/54/EC Method B6. Ten test and five control guinea pigs were used for this study. Based on the results of the sighting tests, the concentrations of test material for the induction and challenge phases were selected as followed: intradermal induction: 5% test substance in liquid paraffin, topical induction: undiluted (20% test substance in liquid paraffin) and topical challenge: undiluted (20% test item in paraffin) and 10% test substance. In conclusion, the undiluted test material (20% in paraffin), produced a 0% (0/10) sensitisation rate and was classified as non-sensitizer to guinea pig skin.
Reference
Skin reactions after intradermal induction:
Discrete or patchy to moderate and confluent erythema was noted at the intradermal induction sites of test group animals. Discrete or patchy erythema was noted at the intradermal induction sites of control group animals.
Skin reactions after topical induction:
Discrete or patchy erythema was noted at the topical induction sites of test group animals. No evidence of erythema or oedema was noted at the topical induction sites of control group animals. Bleeding from the intradermal injection sites was noted in six test group animals and one control group animal.
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)

Migrated from Short description of key information:
In conclusion, the test undiluted test material, produced a 0% (0/10) sensitisation rate and was classified as non-sensitizer to guinea pig skin.
Justification for selection of skin sensitisation endpoint:
One reliable study is available which is GLP/guideline compliant.
Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
The test substance is not considered to be classified for skin sensitization under Regulation (EC) No 1272/2008 (CLP).
