0.1 g of the test material was instilled into the conjunctival sac of the left eye of each animal. After instillation the eye lid was closed for approx. 30 seconds.

In animals 2 and 3 similar signs of irritation were seen. The conjunctivae showed slight redness and chemosis at the first reading (1 h). Furthermore, discharge was seen. Thereafter no signs of irritation were observed. The untreated eyes were unchanged.

- There was no mortality and no signs of toxicity were observed during the study period. The body weight gains were within the normal ranges during the study period.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item is not irritating to eye.
- Executive summary:
The test item was tested for its eye irritating properties. Prior to testing, the HET-CAM test was performed and no irritating potential could be detected. The test for primary eye irritation was started as an initial test with one animal and followed by the confirmatory test with two further animals.
For the test of primary eye irritation, 0.1 g of 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 were performed daily for further 7 days.
No signs of irritation could be observed at the cornea or iris. The conjunctivae showed redness (score 1) at the first (1 hour) and second reading (24 hours) and only in one animal chemosis (score 1) at the first reading (1 hour). Furthermore, discharge (score 1) at the first reading was seen. Thereafter no signs of irritation were observed. The untreated eyes were unchanged.
Except for a slight reddening, chemosis and discharge of the conjunctivae at the first and second reading (24 hours), which were regarded due to mechanical irritation, no signs of irritation was observed. Therefore, the test item should not be regarded as an irritant to the eyes.

In vivo skin irritation study
To test for primary skin irritation, 0.5 g of 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 6 cm2 patches and applied to the intact skin of previously shaven rabbits for a 4 hours period under semiocclusive conditions. The study was started as an initial test with one animal and followed by the confirmatory test with two further animals. The first examination of the treated skin sites followed 1 hour after removal of the patches. Thereafter, examinations were performed daily for further 7 days.
Under the conditions of the present study, no signs of irritations were seen. Therefore, the test item is not considered to be irritating to skin.
In vivo eye irritation study
The test item was tested for its eye irritating properties. Prior to testing, the HET-CAM test was performed and no irritating potential could be detected. The test for primary eye irritation was started as an initial test with one animal and followed by the confirmatory test with two further animals.
For the test of primary eye irritation, 0.1 g of 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 were performed daily for further 7 days.
No signs of irritation could be observed at the cornea or iris. The conjunctivae showed redness (score 1) at the first (1 hour) and second reading (24 hours) and only in one animal chemosis (score 1) at the first reading (1 hour). Furthermore, discharge (score 1) at the first reading was seen. Thereafter no signs of irritation were observed. The untreated eyes were unchanged.
Except for a slight reddening, chemosis and discharge of the conjunctivae at the first and second reading (24 hours), which were regarded due to mechanical irritation, no signs of irritation was observed. Therefore, the test item should not be regarded as an irritant to the eyes.
Justification for classification or non-classification
The available data on skin and eye irritation do not meet the criteria for classification according to Regulation (EC) 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
