Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In accordance with the provisions of regulation 1272/2008, Annex I, 3.3, Dechlorane Plus is not classified as irritating to rabbit eyes.
- Executive summary:
Groups of 3 rabbits each were applied with 0.1 ml of Dechlorane Plus undeluted into the right eye, while the left eye served as control. In two groups, the treated eyes were washed after 2 or 4 seconds. The reactions were recorded at 24, 48, and 72 hours after application according to Draize. No irritant effect at all was observed in any animal at any time point. Dechlorane Plus was completely non irritant.
