Applicant's summary and conclusion
- Executive summary:
In a skin irritation/corrosion study in rabbits according to OECD TG 404 and GLP the animals were treated with 500 mg of test substance moistened with 0.18 ml isotonic saline for 4 hours. 30 -60 minutes after patch removal in all animals a very slight erythem could be observed. After 24 hours after patch removal in all animals no irritation symptoms could be observed any more.
The test substance was evaluated to be not irritating according to directive 83/467/EWG.
