Irritant / corrosive response data:

The test material did not induce any changes to iris and cornea of test animals. Conjunctivae of test animals showed a slight erythema 1 hour after application. All effects were fully reversible within 48 hours.

Other effects:

4 animals showed a slight exsudation 1 hour after application which was fully reversible within 24 hours.
