Irritant / corrosive response data:
Reversibility of any observed effect: Changes not fully reversible within 27 days
Other effects:
Test site hardening and thickening was noted in 2 animals24h after patch removal. Scabbing was noted at the testsite of the remaining animal 72h after patch removal.No animal had fully recovered by the end of the observationperiod. Skin at the test site was thickened, hardened andscabbed up to the end of the observation period 27 daysafter patch removal. On the basis of the test sitehardening and scabbing, SNEA has been classified as anirritant.
