Conclusions:
Skin irritation test was performed according to OECDTG 404 and GLP: 500 µl was applied to the shaved back of each of 3 rabbits and covered by semi-occlusive dressing. The exposure time was 4 hours.The opposite side of the back served as control. After removing of the dressing the treated area was carefully washed. The observation period lasted 14 days. The area were evaluated according to prescription of the guideline. No erythema(score0 of mac 4) or edema (score 0 of max 4) were observed in none of the 3 rabbits. Therefore, the test compound can be evaluated as not irritating to the skin. According to CLP classification criteria (Regulation (EC) No 1272/2008) a classification is not justified.

100 µl of the test compound was instilled into the conjunctival sac of one eye of each of 3 rabbits after gently pulling the lower lid away from the eyeball. The lids were then gently held together for about one second . The treated eye was washed out with physiological saline 24 hours after instillation of the test compound. The other eye remained untreated and served as control . Eye irritation was scored according to Draize during the observation period of 21 days

Additional information

Skin Irritation:

Skin irritation test was performed according to OECDTG 404 and GLP: 500 µl was applied to the shaved back of each of 3 rabbits and covered by semi-occlusive dressing. The exposure time was 4 hours. The opposite side of the back served as control. After removing of the dressing the treated area was carefully washed. The observation period lasted 14 days. The area was evaluated according to prescription of the guideline. No erythema (score 0 of max 4) or edema (score 0 of max 4) were observed in none of the 3 rabbits. Therefore, the test compound can be evaluated as not irritating to the skin.

Eye irritation test

Eye irritation test was performed according to OECD TG 405 and GLP: 100 µl of the test compound was instilled into the conjunctival sac of one eye of each of 3 rabbits after gently pulling the lower lid away from the eyeball. The lids were then gently held together for about one second. The treated eye was washed out with physiological saline 24 hours after instillation of the test compound. The other eye remained untreated and served as control. Eye irritation was scored according to Draize during the observation period of 21 days. No reactions in conjunctivae, cornea or iris of the eyes were observed in none of the 3 rabbits (Score 0). Therefore, the test compound is evaluated as not irritating to the eyes of rabbits
