Applicant's summary and conclusion

Interpretation of results:
other: no to slight irritation
Remarks:
Criteria used for interpretation of results: expert judgment
Conclusions:
Interpretation must be made in the context of no occlusion during the exposure
Executive summary:

Smyth et al (1954) reported Grade 1 irritation, the least visible capillary injection, following application of undiluted isopropyl acetate to the clipped skin of rabbits for 24 hours. This is interpreted as to indicate "no to slight irritation" potential. However, the study was performed without occlusion.
