Additional information
Skin irritation/corrosion
The irritancy potential of the test substance to skin was evaluated according to OECD guideline 404 and in compliance with GLP (M-000708-03-1). In this study, 0.5 g test substance (purity 97.3%) was applied to the shaved skin of the left or right flank each of 3 New Zealand White rabbits under a semi-occlusive dressing for 4 h. A with water moistened patch was placed on the opposite flank for control. After exposure ended the skin was washed with water and scored for erythema and edema at reading time points 1, 24, 48 and 72 h and 7 days after removal of the dressing. The test item induced very slight erythema (grade 1) that were noted for all three animals 1 h after exposure. This effect was unchanged at later time points and full reversibility observed within 48 h (1/3 animals) or 72 h (2/3 animals). No effect on edema was observed in all three animals. Thus, the mean erythema score (24/48/72 h) was 0.7 in 2/3 rabbits with effects being fully reversible within 72 h, and the same score was 0.3 in 1/3 rabbits with effects being fully reversible within 48 h. The mean edema score (24/48/72 h) was 0 for all three animals tested. No other cutaneous reactions were observed until the end of the study. In conclusion, the test substance did not exhibit skin-irritating properties in the conducted study.
Eye irritation
A GLP-conform eye irritation/corrosion study was performed according to OECD guideline 405 to evaluate the eye irritancy potential of the test substance (M-000708-03-1). A single dose of 0.1 mL (equivalent to approx. 50 mg) test substance (97.3% purity) was instilled to the eye of each of three New Zealand White rabbits. After 24 h of exposure, the test substance was washed off the eyes with physiological saline solution.The test item induced slight chemosis at the 1 h reading time point in 2/3 animals (grade 1) and mild chemosis in 1/3 animals (grade 2), respectively. This effect was fully reversible within 24 h (1 animal scored grade 1 at 1 h) or 48 h (1 animal scored grade 2 and 1 animal scored grade 1 at 1 h), respectively. Furthermore, conjunctivae redness was observed 1 h after administration with all three animals being scored grade 1 for this reading time point. This effect was fully reversible within 24 h (1/3 animals) or 48 h (2/3 animals), respectively. No effects on iris and cornea opacity were noted in any animal. No further ocular reactions were observed until the end of the study. Mean scores evaluated over 24, 48 and 72 h for chemosis and conjunctivae redness were 0.3, 0.3 and 0.0 for the three animals exposed and 0.0 for iris and cornea opacity for all three animals. In conclusion, the test substance did not exhibit eye-irritating properties in the conducted study.
Justification for classification or non-classification
The available data on skin and eye irritation/corrosion do not meet the criteria for classification according to Regulation (EC) No. 1272/2008 and are therefore conclusive but not sufficient for classification.
