Applicant's summary and conclusion

Interpretation of results:
not sensitising
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Acetophenone was assessed as non-sensitiser in a Maximization test with humans.
Executive summary:

The maximization test was carried out on 25 volunteers. The material was tested at a concentration of 2% in petrolatum and produced no sensitization reactions.
