More Information
Summary:A method for preparing alkali metal bicarbonate particles by crystallization from an alkali metal carbonate and/or bicarbonate solution with an additive present in the solution, chosen from among sulfates, sulfonates, polysulfonates, amines, hydroysultaines, polycarboxylates, polysaccharides, polyethers and ether-phenols, alkali metal hexametaphosphate, phosphates, sulfosuccinates, amidosulfonates, amine sulfonates, preferably chosen from among polysaccharides, and such that the additive is present in the solution at a concentration of at least 1 ppm and preferably at most 200 ppm.
