Additional information
Skin irritation
In the key skin irritation study (BASF AG, 1976, equivalent to OECD 404) two rabbits were treated once with the test item via occlusive dermal exposure for 20 h. Animals were observed after 24h, 48h and at day 6 and 8 after exposure. Skin reactions were observed and scored according to the BASF scoring system which was converted into Draize Scores. Thereby animals showed an average edema scores of 1 and 1.5 (24h and 48h), which were fully reversed within the observation period. No other irritating effects were observed and thus the test item was classified as not irritating to skin.
Eye irritation
In the key eye irritation study (BASF AG, 1976, equivalent to OECD 405) two Vienna White rabbits were treated once with 50 mg of the test item by single exposure without washing of the eyes. The second eye of each animal was treated with talcum. Eye reactions were observed and scored according to Draize 10 min, 1 h, 3 h, 24 h, 48 h, and 4, 7 and 8 days after the start of treatment. One animal showed a mean conjunctivae score of 0.5 (time point: 24 -48h) which was fully reversible within 48 h. All other irritation parameters showed a score of 0 indicating that the test item was not irritating to the eyes under the conditions of the study.
Justification for selection of skin irritation / corrosion endpoint:
most reliable study
Justification for selection of eye irritation endpoint:
most reliable study
Justification for classification or non-classification
Based on the results of the skin and eye irritation studies the test item does not need to be subjected to classification and labelling according to Directive 67/548/EEC (DSD) and Regulation (EC) No 1272/2008 (CLP/GHS).
