Applications & Usage

MGDA.Na3 is widely used in laundry & dish washing, personal care and household Cleaning. In household cleaning, MGDA.Na3 can replace phosphorous containing builders in dishwashing detergents. MGDA.Na3 enhances the cleaning power of a cleaner / detergent by sequestering hard water ions from water and dirt. It prevents the deactivation of surfactants from hard water metal ions. It also deactivates transition metal ions thus stabilizing detergents that contain peroxides. In industrial & Institutional cleaning, MGDA.Na3 forms stable, water-soluble metal complexes with all potentially harmful metal ions. It dissolves existing and prevents new scales from causing problems in water circulation equipment (in e.g. the power, brewing, and sugar industries). Because of its low molecular weight this chelate performs very well in short contact cleaning. MGDA.Na3 is also very suitable as a metal carrier, a stabilizer of process baths and for neutralizing trace impurities.
