Definitions
- Liquid detergents are known in the art and have become increasingly popular with consumers in recent years as they offer a number of advantages over solid detergents. These include, among other things, the simpler dosage, addition and dissolution in the wash liquor. In addition, they are perceived as safer and less aggressive to the textiles and the environment. Especially for the washing of colored textiles, they have gained more and more popularity since their market launch.
