Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information
- Conclusions:
- From the results described above a mild allergenic potency of the test article diluted to 10% i n petrolatum oil was concluded after first challenge application. After second application no allergenic potency of the test article diluted to 10% in petrolatumoil was observed when the results were interpreted according to the rating of Magnusson and Kligman (1970).
According t o the EEC (European Economic Community) classification criteria described in wide lines 831467, September 16, 1983, this test article is considered to be a non-sensitizer.
