Abstract (en)

[origin: WO2020011764A1] The invention relates to an anti-scaling composition comprising a combination of a uronic acid containing polyasaccharide (i) and a scaling-inhibiting agent(ii). The uronic acid containing polysaccharide (i) has a solubility in water at a temperature of 25 °C ranging between 1 g/L and 700 g/L and a mass average molecular weight Mw ranging between 1 and 500 kDa. The invention also relates to an automatic dishwashing detergent product comprising such an anti-scaling composition and a surfactant. The invention also relates to an anti-deposition product comprising such an anti-scaling composition and a bleaching agent. The invention further relates to a process for preventing scale-formation in water-using and/or water-processing equipment and to the use of a uronic acid containing polysaccharide (i) for improving the scale-inhibiting performance of a scale-inhibiting agent (ii).
