Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions, the test material induced very slight to slight irritation being reversible within 48 hours. Therefore the test material is not classified as irritant to the eyes according to the criteria of the Annex VI of the Regulation (EC) No. 1272/2008 (CLP) and of the GHS.
- Executive summary:
In an eye irritation study performed according to the OECD guideline No. 404, and in compliance with GLP, 0.1 mL of test material was instilled into the left eye of 3 male New Zealand White rabbits. The eyes were not rinsed after the instillation of the test material. The right eye of each rabbit served as control. Animals were observed at 1 hour, 24, 48 and 72 hours after dosing. No further observation was performed since complete reversibility was achieved within 48 hours. 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.
The individual score for each animal within 3 scoring times (24, 48 and 72 hours) were as follows: 0.0 / 0.33 / 0.33 for redness, 0.0 / 0.0 / 0.33 for chemosis.
No other ocular reactions were observed during the study.
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 GHS.
This study is considered as acceptable and satisfies the requirement for skin irritation endpoint.
