Zeolites in the powder make it possible to use less surfactants by reducing the hardness of the water, because the main function of zeolite is to reduce water hardness. The main detergent component – surfactant – easily copes with dirt when the water is already “soft”. Frosch uses zeolites in dry laundry detergents, based on the results of a comprehensive study by the German Federal Environmental Service, which has proven the environmental safety of this component.

Zeolites are used in washing powders to soften water: the zeolite reacts with the calcium and magnesium contained in the water and binds them during the entire washing process, so that they do not remain on the laundry or in the washing machine.

An extensive study by the German Federal Environmental Service has not found any negative impacts on the environmental compatibility of zeolite. Zeolites allow you to completely eliminate the use of phosphates in detergents. Zeolite is non-toxic and environmentally neutral, so bloom can be reduced. The mineral simply remains in the sewage sludge. The study by the German Federal Environmental Service is a series of scientific studies, publications and books.
