Executive summary:

A study was performed according to GLP and methods applied were fully compliant with OECD 404. The test material was mixed with some drops of Aqua pro injectione to ensure good contact with the skin. Afterwards, the test material was spread onto patches and applied to the intact skin of previously shaven rabbits for 4 hours under semi-occlusive conditions. The study was performed initially with one animal and followed by the confirmatory test with two further animals. The first examination of the treated skin followed 1 hour after patch removal. Thereafter, examinations were performed daily for a further 7 days. Under the conditions of the present study, no signs of irritation were seen. Body weight development of the treated rabbits was inconspicuous. Thus, no skin irritating potential could be detected for the test item.

Irritant / corrosive response data:
No signs of irritation were observed at the cornea or iris. All animals showed discharge (score 1) one hour after instillation of the test material. In two animals redness (score 1) was observed one hour after treatment. No abnormalities were detected in the untreated eyes.
Other effects:
none
Interpretation of results:
GHS criteria not met
Conclusions:
The test item showed no relevant eye irritating potential.
Executive summary:

The test material was tested for its eye irritating properties according to OECD 405 under GLP conditions. Prior to testing, the hen's egg test on the chorioallantoic membrane was performed and no irritating potential could be detected. The test for primary eye irritation was performed initially with one animal and followed by the confirmatory test with two further animals. For the test of primary eye irritation, the test material was applied into the conjunctival sac of rabbits. The first examination of the eyes followed 1 hour after instillation. The other examinations of the eyes were performed daily for a further 7 days. No signs of irritation were observed at the cornea or iris. All animals showed discharge (score 1) one hour after instillation of the test material. In two animals redness (score 1) was observed one hour after treatment. No abnormalities were detected in the untreated eyes. No relevant eye irritating potential could be detected. The test material should not be classified as an eye irritant.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. Based on available data on skin and eye irritation, the test item does not require classification for skin and eye irritation according to Regulation (EC) No 1272/2008 (CLP).
