Skin corrosion/ irritation	WoE No valid studies are available. All available data get a K4 since no original references are available only secondary references. The results from animals studies show mild to moderate irritation. There are two studies available with human volunteers. 4% does not result in skin irritation the neat substance applied to the skin under occlusion 24-48h give slight to irritating reactions in 14 out of 212 volunteers. Based on the responses observed severe effects on the skin are not expected.The lack of individual scores and the use of a non-standard technique preclude classification on the basis of EU or GHS criteria. A precautionary approach is chosen and the substance is classified: Irritant, Category 2   Classification and Labeling Irritant, Category 2
