Abstract

Use of phytate to inhibit the nucleation and growth in water of salts with one divalent cation selected from Ca2+ and Mg2+. This manages to prevent the crystallisation of calcium and magnesium salts by using very small amounts of product and without reducing the concentration of other essential mineral elements present in said water.
