Applicant's summary and conclusion

Interpretation of results:
not sensitising
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
No evidence of sensitisation observed
Executive summary:

No evidence of sensitisation observed

Even when considering the absence of key data in the published report, the conclusions made at the time by those undertaking the review are that the substance can be used in dermally applied cosmetic products. Human monitoring is also reported and no evidence of sensitising effects is reported.

No claims for data ownership are made and it is noted that the review relied on data from industry testing on similar substances.

There is no justification to perform further animal tests on this substance, especially in regard to its use in cosmetic products.
