Alcoguard® H5941 represents the second generation of hybrid polymers. Hybrid polymers are a marriage of selected polysaccharides and synthetic monomers, designed to prevent scale formation in detergent applications such as automatic dishwash, hard surface cleaning and laundry detergent systems. They are particularly effective at minimizing filming and spotting in zero phosphate automatic dishwash formulations and works as effective as synthetic co-polymers.
