Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Based upon the reffered clasification criteria (Commossion Directive 2001/59/EC of August 06, 2001), GRO 266 is considered to be "not irritating" tothe rabbit eye.
based upon the Kay and Calandra classification criteria, GRO 266 is considered to be "slightly irritating" to the rabbit eye (Maximum Average Score = 8.00).
Executive summary:

The primary eye irritation of GRO 266 was investigated according to OECD test guideline no. 405. The test item was applied by instillation of 0.1 g into the left eye of each of three young adult New Zealand White rabbits. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours after test item instillation.

The mean score was calculated across 3 scoring times (24, 48 and 72 hours after instillation) for each animal for corneal opacity, iris, redness and chemosis of the conjunctivae, separately. The individual mean scores for the conjunctivae were 0.33, 0.67 and 0.33 for reddening and 0.00 for chemosis for each of the three animals.

The instillation of GRO 266 into the eye resulted in mild to moderate, early-onset and transient ocular changes, such as reddening of the conjunctivae and sclerae, discharge and chemosis. These effects were reversible and were no longer evident 72 hours after treatment in all animals. No abnormal findings were observed in the cornea or iris of any animal at any of the examinations. No corrosion was observed at any of the measuring intervals. No staining of the treated eyes by the item was observed and no clinical signs were observed.

Thus, the test item did not induce significant or irreversible damage to the rabbit eye.

Based upon the referred classification criteria (Commission Directive 2001/59/EC of August 06, 2001), GRO 266 is considered to be "not irritating" to the rabbit eye.

Based upon the Kay and Calandra classification criteria, GRO 266 is considered to be "slightly irritating" to the rabbit eye (Maximum Average Score = 8.00).
