Applicant's summary and conclusion
- Interpretation of results:
- other: not classified according to the EU Directive 67/548/EEC
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:
- The test material, OS 144267, produced a maximum group mean score of 5.3 and was classified as a MINIMAL IRRITANT (CLASS 3 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:
A GLP study was performed to assess the irritancy potential of the test material to the eye of the New Zealand White rabbit. The method used followed that described in the OECD guideline 405 and in the EU Method B.5. A single instillation of 0.1 mL of undiluted test material to the non-irrigated eye of three rabbits produced minimal conjunctival irritation. All treated eyes appeared normal at the 24-hour observation. No control animals were used. One eye of each animal remained untreated and was used for control purposes. The test material produced a maximum group mean score of 5.3 and was classified as a minimal irritant (Class 3 on a 1 to 8 scale) to the rabbit eye according to a modified Kay and Calandra classification system. However the test material did not meet the criteria for classification as irritant according to EU labelling regulations (Directive 67/548/EEC). No symbol and risk phrase are required.
