The toxic or allergic contact dermatitis is the most frequent occupational disease of the skin. It is caused by repeated contact with irritant or sensitizing occupational substances. The aim of the skin protection is to prevent or at least to lessen the contact with these injuring substances. Protective gloves as well as skin protective unguents are of use for preventive skin protection. We differentiate two types of emulsions among the skin protective unguents: O/W-emulsions protect against injuring components, insoluble in water, and W/O-emulsions protect against injuring stuffs, soluble in water. The cleaning agents of the skin have to be chosen according to the degree and kind of the contamination; today surfactants such as soap and detergents are chiefly used. THe preserving skin protection is very important: with the regenerating care of the skin the water and fatty constituents of the injured skin are repaired.
中毒性或过敏性接触性皮炎是最常见的皮肤职业病。它是由反复接触刺激性或致敏性职业物质引起的。皮肤保护的目的是预防或至少减少与这些有害物质的接触。防护手套和皮肤保护软膏对预防性皮肤保护有用。在皮肤保护软膏中，我们区分两种类型的乳液：水包油型乳液可防止不溶于水的有害成分，油包水型乳液可防止可溶于水的有害物质。皮肤清洁剂必须根据污染的程度和种类来选择；如今主要使用肥皂和洗涤剂等表面活性剂。保持皮肤保护非常重要：通过对皮肤的再生护理，受损皮肤的水分和脂肪成分得以修复。
