- Irritant / corrosive response data:
- Slight conjunctivae redness was observed in all animals one hour after application, but was no longer detectable in two animals at the 24 h reading. Only one animal revealed conjunctivae redness at the 24 h reading, but not at later time points (for details see table below). Chemosis (score 1 or 2) was observed in all animals one hour after application of the test item, but not at later time points. Iris and cornea were not affected.
A black discharge was observed in all animals at the 1 h reading. Diffuse crimson coloured conjunctivae was observed in one animal at 24 hours. No signs of irritation were apparent after 48 hours. - Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The test item was not irritating to the eyes of rabbits under the conditions of this test.
- Executive summary:
The primary irritation potential of the test item was investigated by instillation of 0.1 g into one eye of each of three young adult New Zealand White rabbits according to OECD TG 405 (adopted 24 February 1987) and GLP. The treated eyes were rinsed with distilled water approximately 24 hours after application. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours after test article application.
Slight conjunctivae redness was observed in all animals one hour after application, but was no longer detectable in two animals at the 24 h reading. Only one animal revealed conjunctivae redness at the 24 h reading, but not at later time points. Chemosis (score 1 or 2) was observed in all animals one hour after application of the test item, but not at later time points. Iris and cornea were not affected. A black discharge was observed in all animals at the 1 h reading. Diffuse crimson coloured conjunctivae was observed in one animal at 24 hours. No effects were observed at the 48 h and 72 h reading. Due to the only sligth, reversible effects observed under the conditions of this test the test item was judged not to be irritating to the eyes.

Additional information
Skin irritation:
No signs of skin irritation, neither oedema or erythema, were observed in rabbits in the reliable key study (RL 1) which was performed according to GLP (Hoechst, 1989).
Eye irritation:
Only slight and fully reversible effects were observed in the reliable key study (RL 1) on eye irritation in rabbits which was performed according to GLP (Hoechst, 1989). Mean scores for all three animals after the 24, 48 and 72 h reading were 0, 0, 0.3, and 0 for cornea, iris, conjunctivae redness and conjunctivae chemosis, respectively, i.e. no classification is necessary.
Respiratory irritation:
No study available
Justification for selection of skin irritation / corrosion endpoint:
Guideline study (OECD TG 404), according to GLP
Justification for selection of eye irritation endpoint:
Guideline study (OECD TG 404), according to GLP
Justification for classification or non-classification
As the submission substance was not irritating to the skin and caused only marginal and fully reversible effects to the eyes in two valid studies performed in accordance with OECD test guidelines and under GLP conditions no classification for eye, skin and respiratory irritation according to Regulation (EC) No 1272/2008 and Council Directive 67/548/EEC is required.
