Executive summary:

In a study conducted in 1979, the test substance Busan 11-M1was examined for its ability to cause skin irritation when tested on intact and abraded rabbit skin. The exposure sites on each animal were shaved and then two sites were left intact and two sites were abraded prior to exposure. The test substance wetted with saline was applied under a gauze pad to the sites. The skin reactions of each test animal were observed for 72 hours. Slight erythema with developed which was fully reversible and was not accompanied by any other irritation reactions. Under the conditions of this study, the test substance Busan 11-M1was considered not to be irritating to intact or abraded rabbit skin. Based on these results, the test substance does not warrant classification for skin irritation in accordance with Regulation EC No. 1272/2008.
