Applicant's summary and conclusion

Interpretation of results:
ambiguous
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Under the experimental conditions of the study, the test item, OIL T279, gave a positive result in the murine Local Lymph Node Assay, indicative of skin sensitization properties.
According to the EC3 value obtained, 10.23%, the test item should be considered as a weak sensitizer.
