Any other information on results incl. tables
No clinical signs of systemic toxicity were observed in the animals during the study and no mortality occurred.
Application of the test item to healthy rabbit conjunctivae resulted in a primary eye irritation score of 0.11. The eye reactions (mean values from 24 to 72 hours) consisted of grade 0.00 corneal opacity, grade 0.00 iris lesions, grade 0.11 redness of the conjunctivae and grade 0.00 chemosis of the conjunctivae. No abnormal findings were observed in the cornea or iris of any animal at any of the measurement intervals. Slight to moderate reddening of the cornea was observed in all animals 1 hour after treatment and slight reddening continued to be observed in one animal up to the 24 hour reading. Slight swelling of the conjunctivae was evident in all animals 1 hour after treatment. Slight to moderate reddening of the sclerea was apparent in all animals at the 1 hour reading. No abnormal findings were observed in the treated eye, of any animal, 48 hours after treatment.
No staining of the treated eyes by the test item was observed. Beige coloured remnants of the test item were observed in the eye or conjunctival sac of one animal at the 1 -hour reading.
No corrosion of the cornea was observed at any of the reading times.
The body weights of all rabbits were considered to be within the normal range of variability.
Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based upon the referred classification criteria (EEC Commission Directive 93/21/EEC of April 27, 1993), TSE 2 is considered to be "not irritating" to the rabbit eye.
