Description of key information
Key value for chemical safety assessment
Skin sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
The skin sensitizing potential of the test item was assessed using the radioactive Murine Local Lymph Node Assay. The assay simulates the induction phase for skin sensitization in mice. It determines the response of the auricular lymph nodes on repeated application of the test substance to the dorsal skin of the ears. Groups of 5 female CBA/J mice each were treated with 3%, 10% and 50% w/w preparations of the test substance in MEK (methyl ethyl ketone) or with the vehicle alone. The study used 3 test groups and 1 control group. Each test animal was applied with 25 μL per ear of the respective test-substance preparation to the dorsum of both ears for three consecutive days. The control group was treated with 25 μL per ear of the vehicle alone. Three days after the last application the mice were injected intravenously with 20 μCi of 3H-thymidine in 250 μL of sterile saline into a tail vein. About 5 hours after the 3H-thymidine injection, the mice were sacrificed and the auricular lymph nodes were removed. The weights of each animal’s pooled lymph nodes were determined. Thereafter lymph nodes were pooled group wise and further evaluated by measuring their cellular content and 3H-thymidine incorporation into the lymph node cells (indicators of cell proliferation). Moreover, a defined area with a diameter of 0.8 cm was punched out of the apical part of each ear and for each test group the weight of the pooled punches was determined in order to obtain an indication of possible skin irritation.
Migrated from Short description of key information:
Based on the results, it is concluded that the lymph node response observed on the presence of some skin irritation cannot be interpreted as indication for skin sensitization. Thus the test item does not show a skin sensitizing effect in the Murine Local Lymph Node Assay under the test conditions chosen.
Justification for selection of skin sensitisation endpoint:
GLP and guideline study
Justification for classification or non-classification
Dangerous Substance Directive (67/548/EEC)
The available study is considered reliable and suitable for classification purposes under 67/548/EEC. As a result the substance is not considered to be classified under Directive 67/548/EEC, as amended for the 31st time in Directive 2009/2/EG.
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008.
The available experimental test data is reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. As a result the substance is not considered to be classified under Regulation (EC) No 1272/2008, as amended for the sixth time in Regulation No 605/2014.
