Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Key value for chemical safety assessment
Skin sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
The test substance was investigated for its sensitizing potential in a GLP-compliant Maximization test according to OECD guideline 406 (CIBA-GEIGY Ltd., 850044, 1993). Pirbright White guinea pigs received intradermal induction treatments with 1% in sesame oil and one epicutaneous induction treatment with 30% in vaseline. For intradermal induction, three pairs of injections (adjuvant/saline; test item in vehicle; test item in vehicle plus adjuvant/saline) were given. Epidermal challenge was performed by occlusive application for 24 h two weeks later (10% in vaseline). No skin reactions were observed either for control or test group animals and therefore no animal was sensitized by the test article under the experimental conditions employed. The sensitivity of the strain is controlled every six month with p - phenylenediamine. In conclusion, the test substance is not considered to be a skin sensitizer in albino guinea pigs and does not require classification.

No data
Justification for classification or non-classification
Dangerous Substance Directive (67/548/EEC)
The available experimental test data is reliable and suitable for the purpose of classification under Directive 67/548/EEC. Based on the present data, classification for sensitization is not warranted under Directive 67/548/EEC.
Classification, Labeling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for the purpose of classification under Regulation (EC) No.1272/2008. Based on the present data, classification for sensitization is not warranted under Regulation (EC) No.1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
