Applicant's summary and conclusion

Interpretation of results:
other: Not irritating
Conclusions:
The test material Isononyl acetate (CAS No: 40379-24-6) was considered to be not irritating to the intact and abraded skin of rabbits.
Executive summary:

Skin irritation study of Isononyl acetate (CAS No: 40379-24-6) was conducted on rabbits to determine the degree of skin irritancy.

 

Each rabbit received neatIsoamyl Propionate on intact and abraded skin for 24 hours under occlusive condition and later observed for skin lesions.

 

Since the treated rabbits showed no signs of irritation, the chemicalIsononyl acetate (CAS No: 40379-24-6)was considered to be not irritating to theintact and abraded skin of rabbits.
