The dishwasher detergent according to the invention is especially suitable for dishwashing in machines with a short washing process such as between 30 seconds and 15 minutes, and where the washing process must be effective.
- The dishwasher detergent has several functions in the process. It must reduce the surface tension of the water in order to increase the wash effect of the water. Further, it must contribute actively to loosen the various kinds of dirt consisting of the various substances contained in food and beverages, e.g. fat, proteins etc.
