Skin sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
The test item was assessed for its possible contact allergenic potential in a local lymph node assay (OECD TG 429). For this purpose the test item was applied to the dorsal surface of the ears of female mice (4 per group) at concentrations of 5, 10, and 25% (w/v) in dimethylformamide for three consecutive days. The animals did not show any clinical signs during the course of the study and no cases of mortality were observed. In this study Stimulation Indices (S.I.) of 1.29, 1.48, and 0.90 were determined with the test item at concentrations of 5, 10, and 25%, respectively. The test item was not a skin sensitiser in this assay.
Migrated from Short description of key information:
Not sensitising in a local lymph node assay in concentrations up to 25% (w/v).
Justification for classification or non-classification
Due to the negative findings in a local lymph node assay the test item has not to be classified as skin sensitiser according to Regulation (EC) No 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
