Irritant / corrosive response data:

No corneal or iridial effects were noted during the study. Minimal conjunctival irritation was noted in all treated eyes one and 24 hours after treatment. Minimal conjunctival redness persisted in one treated eye at the 48-hour observation. Two treated eyes appeared normal at the 48-hour observation and the remaining treated eye appeared normal at the 72-hour observation.

Other effects:

None

Applicant's summary and conclusion

Interpretation of results:

not irritating

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

Under the test conditions, the test material induced a slight irritation, being largely reversible within 72 hours following instillation. Therefore, the test material is not classified as irritating to eyes according to the criteria of the Annex VI of the Regulation (EC) No 1272/2008 (CLP) and of the Directive 67/548/EEC.

Executive summary:

In an eye irritation study performed according to the OECD guideline No. 405, and in compliance with GLP, 0.1 mL of undiluted test material was instilled into the right eye of 3 New Zealand White Rabbit. The eyes were not rinsed after the instillation of the test item. The left eye of each rabbit served as control. Animals were observed at 1, 24, 48 and 72 hours after dosing under a standard light source. The reactions in the conjunctiva (redness, chemosis and discharge), the iris and the cornea (opacity and area involved) were scored according to the Draize scale.

No corneal or iridial effects were noted during the study. Minimal conjunctival irritation was noted in all treated eyes one and 24 hours after treatment. Minimal conjunctival redness persisted in one treated eye at the 48-hour observation. Two treated eyes appeared normal at the 48-hour observation and the remaining treated eye appeared normal at the 72-hour observation

The calculated mean score for each individual lesion for each individual animal within 3 scoring times (24, 48 and 72 hrs) were as follows: 0.3/0.7/0.3 for redness, 0.3/0.3/0.3 for discharge and 0/0/0 for chemosis, iris and corneal lesions.

The effects observed were all reversible within 72 hours.

Under the test conditions, the test material is not classified as irritating to eyes according to the criteria of the Annex VI of the Regulation (EC) No 1272/2008 (CLP) and of the Directive 67/548/EEC.

This study is considered as acceptable and satisfies the requirement for eye irritation endpoint.
