Summary from report of the skin irritation
Primary skin irritation/ corrosion study with Everzol Orange ED-G Crude in the rabbit ( 4hr semi-occlusive application). Three rabbits were exposed to 0.5 grams of Everzol Orange ED-G Crude, moistened with 0.5 ml water by application onto clipped skin for 4 hours using a semi-occlusive dressing. Skin reactions were assessed 1, 24, 48 and 72 hours after exposure. No skin irritation was caused by 4 hours exposure to Everzol Orange ED-G Crude. Brown/orange staining of the treated skin by the test substance was observed throughout the observation period, which did not hamper the scoring of the skin reactions. No remnants of the test substance were present on the skin. Based on these results, Everzol Orange ED-G Crude does not have to be classified and has no obligatory labeling requirement for skin irritation according to GHS and EC 67/548/EEC.
