In vitro test system
- Details on the study design:
- Cells seeding was performed on the first day. The preparation of the test item dilutions were conducted the following day. Test system included negative and postivi controls. According to protocol, contact between the cells and the test and reference items were made during the second day. The day four consisted Luciferace activity observations and cell viability assessment with MTT method.
Results and discussion
- Positive control results:
- Positive controls showed results that are met in OECD validation dataset, between 7 µM and 30 µM.

Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (skin sensitising) based on GHS criteria
- Conclusions:
- Under the retained experimental conditions Pine tar may be classified as sesitizer.
- Executive summary:
The pine tar was studied for sensitising properties using Keratinosens test. Under the retained experimental conditions Pine tar may be classified as sensitizer.
