Applicant's summary and conclusion

Interpretation of results:
other: not sensitizing
Conclusions:
The test material Allyl butyrate (CAS No: 2051-78-7) was considered to be not sensitizing to the skin of human volunteers.
Executive summary:

A Human maximisation test was carried out in 28 volunteers to determine skin sensitization potential caused by the chemicalAllyl butyrate(CAS No: 2051-78-7).

 

Each subject was treated with 4% ofAllyl butyratein petrolatum dermally and later observed for any signs of contact allergy.

 

None of the volunteer showed any signs of contact sensitization. Hence the chemical Allyl butyrate(CAS No: 2051-78-7) wasconsidered to be not sensitizing to theskin of human volunteers.
