Study design


To test for primary skin irritation, 0.5 g of the test material, 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.


 


Results


Under the conditions of the present study, no signs of irritation were seen.


 


Body weight development of the treated rabbits was inconspicuous.


 


Conclusions


No skin irritating potential could be detected.

Interpretation of results:
GHS criteria not met
Conclusions:

Irritant / corrosive response data:
No signs of irritation were observed at the cornea or iris. One hour and 24 hours after treatment, the conjunctivae showed redness (score 1). Furthermore, discharge (score 1) was seen at the first reading. Thereafter no signs of irritation were observed. The untreated eyes were unchanged.
Other effects:
none
Interpretation of results:
GHS criteria not met
Conclusions:
According to these results, for regulatory purposes the test material has to be classified as non-irritant for the eyes.
Executive summary:

Study design


The test material was tested for its eye irritating properties. 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 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 of the eyes were performed daily for further 7 days.


 


Results


No signs of irritation were observed at the cornea or iris. One hour and 24 hours after treatment, the conjunctivae showed redness (score 1). Furthermore, discharge (score 1) was seen at the first reading. Thereafter, no signs of irritation were observed. The untreated eyes were unchanged.


 


Conclusion


According to the EEC-Directive 2001/59 the test material should not be regarded as an irritant to the eyes.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not irritating)

Respiratory irritation

Endpoint conclusion
Endpoint conclusion:
no study available

Additional information

Justification for classification or non-classification

No adverse effects have been observed and thus no classification is needed.
