• the detergent according to the invention is particularly suitable for washing with "hard” water, such as tap water.
• detergents are used for washing color materials in the form of piece goods. However, they are not suitable for washing dyeing material in the form of packages or loose material. These detergents are also less stable in storage.
• the detergent according to the invention can additionally contain an anionic surfactant as component (C) and a nonionic surfactant as component (D).
