Score:
ca. 0 - ca. 3
Max. score:

Remarks on result:
other: Individual eye irritation scores are below in Table 1.
Irritant / corrosive response data:
Corneal injury consisted of opacity (maximum grade 1) and epithelial damage (maximum 75% of the corneal area in one animal and 50% in the other two animals). As a result of the corneal injury, in two animals pannus (neovascularisation of the cornea) was apparent 7 and 14 days after instillation. The corneal injury had resolved within 7 days in one animals and within 21 days in the other two animals. Iridial irriation grade 1 was observed and had resolved within 7 days in all animals. The irritation of the conjunctivae consisted of redness, chemosis and discharge and had completely resolved within 21 days in one animal and within 14 days in the other two animals.

Applicant's summary and conclusion

Interpretation of results:
Category 2A (irritating to eyes) based on GHS criteria
Remarks:
Migrated information
Conclusions:
Under the conditions of the study, the test substance caused severe eye irritation which was fully reversible within 21 days. Based on these results the test substance should be classified as irritating to eyes (Category 2A according to GHS criteria and R36 according to EC criteria).
Executive summary:

The purpose of this study was to assess the acute eye irritancy/corrosivity of the test substance in rabbits according to OECD Test Guideline 405. Single samples of 0.1 ml of the test substance were instilled into one eye of each of three rabbits. Observations were made 1, 24, 48 and 72 hours and 7, 14 and 21 days after instillation. Instillation of the test substance resulted in effects on the cornea, iris and conjunctivae. The corneal injury consisted of opacity (maximum grade 1) and epithelial damage (50-75% of the corneal area). As a result of the corneal injury, pannus (neovascularisation of the cornea) was apparent 7 and 14 days after instillation in two animals. The corneal injury had resolved within 7 days in one animal and within 21 days in the other two animals. lridial irritation grade 1 was observed and had resolved within 7 days in all animals. The irritation of the conjunctivae consisted of redness, chemosis and discharge and had completely resolved within 21 days in one animal and within 14 days in the other two animals. Under the conditions of the study, the test substance caused severe eye irritation which was fully reversible within 21 days. Based on these results the test substance should be classified as irritating to eyes (Category 2A according to GHS criteria and R36 according to EC criteria).
