Abstract: The invention relates to the use of an agent that contains 5 to 99.9% in weight of carbamide and/or at least a derivative thereof, as a cleaning agent for closed systems, in particular as a dishwasher detergent, as a laundry detergent for washing machines, as an agent for cleaning, sanitizing and/or disinfecting for equipment in the food processing industry and for medical equipment, the use as a hand dishwashing detergent or sanitary cleaner or as a hand cleaner. In addition, the invention relates to a method for reducing or avoiding enzymes in cleaning agents for closed systems, in hand dishwashing detergents or in sanitary cleaning agents as well as an enzyme-free dishwashing detergent or enzyme-free sanitary cleaning agent that contain 5 to 99.9% in weight of carbamides or derivates thereof. Finally, the invention relates to the use of percarbamide as a bleaching agent in particular in dishwashing detergents and in sanitary toilet cleaning agents.

Abstract: The invention relates to the use of an agent that contains 5 to 99.9% by weight of carbamide and/or at least a derivative thereof, as a cleaning agent e.g. for closed systems, in particular as a dishwasher detergent, as a laundry detergent for washing machines, as an agent for cleaning, sanitizing and/or disinfecting for equipment in the food processing industry and for medical equipment, the use as a hand dishwashing detergent or sanitary cleaner or as a hand cleaner.
