Any other information on results incl. tables
Suppuration, contracted pupil, discharge of blood and injected scleral vessels in a circumscribed area or circular were noted during the observation period within the first 72 hours. All findings were fully reversible within 7 days at the latest.
The average score (24 to 72 hours) for irritation was calculated to be 1.0 for corneal opacity, 0.44 for iris, 2.33 for conjunctival redness and 1.67 for chemosis.
EU-classification: The mean scores calculated over all animals tested were below 2 for corneal opacity, below 1 for iris lesions, below 2.5 for redness of the conjunctivae and below 2 for edema formation. There was only one animal with a mean score of 2.67 for redness, the other two animals were at 2 and 2.33. Therefore the substance is considered to be not irritating to the eye of rabbits according to EU-criteria under the conditions of the study. GHS-classification (UN): As the mean score of corneal opacity was 1 in 3/3 animals and the mean score for redness was 2, 2.33 and 2.67 in the animals respectively and all readings were reversed to 0 at the 7 day reading, the substance has to be classified as mildy irritating to eyes (Category 2B) according to GHS-criteria. The substance is classified in Annex I as irritating to eyes, respiratory system and skin.
Applicant's summary and conclusion
- Interpretation of results:
- Category 2B (mildly irritating to eyes) based on GHS criteria
