Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test material produced a maximum group mean score of 18.0 and was classified as a MODERATE IRRITANT (CLASS 5 ON A 1 TO 8 SCALE) to the rabbit eye according to a modified Kay and Calandra classification system.
The test material did not produce positive criteria in any rabbit according to the EU labelling regulations. No symbol and risk phrase are therefore required. - Executive summary:
The test substance was investigated for its potential to cause irritation in the rabbit eye according to OECD TG 405 ("Acute Eye Irritation/Corrosion" (adopted 24 February 1987) and Method B5 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
0.1 ml ( 70 mg) of the test substance was administered into the conjunctival sac of one eye of each test animal, the untreated eye served as control. Under the conditions of this experiment the test compound was found to cause moderate irritation, when applied to the rabbit eye. After 7 days, the eyes of all the animals were free of signs of irritation.
The test material produced a maximum group mean score of 18.0 and was classified as a moderate irritant (Class 5 on a 1 to 8 scale) to the rabbit eye according to a modified Kay and Calandra classification system.
The test material did not meet the criteria for classification as irritant according to EU labelling regulations. No symbol and risk phrase are required.
