Additional information

Skin irritation

A GLP conform in vivo study was performed to assess the acute dermal irritation or corrosion potential of the test substance in White New Zealand rabbits according to the OECD guideline 404 (1989). An amount of 0.5 ml of the test substance was once topical applied for 4 hours to the intact skin of three rabbits, using a patch of 12-16 cm2, covered with occlusive dressing. The average score (24 to 72 hours) for irritation effects was calculated to be 0.3 for erythema and 0 for edema. Signs of skin irritation were reversible within 7 days after removal of the patches. Considering the described skin reactions, the test substance does not show a skin irritation potential under the test conditions chosen.

 

Eye irritation

To assess the acute eye irritation potential of the test substance in vivo a GLP conform eye irritation test in White New Zealand rabbits was performed according to the method described in OECD guideline 405 (1989). An amount of 0.1 ml of the test substance was single ocular applied to three rabbits. The average score (24 to 72 hours) for irritation was calculated to be 0.0 for corneal opacity and iris, 0.67 for conjunctivae redness and 0.22 for chemosis. The findings were reversible in all animals within 14 days after application, thus the study was terminated. Symptoms observed and described in the respective observation table in detail together with the average score for irritation do not indicate an irritant property of the test substance to the eye.
