Abstract: The present invention is directed towards a process for making a powder or granule containing (A) at least one alkali metal salt of citric acid, and at least one additive selected from (B) at least one (co)polymer containing carboxylic acid groups, partially neutralized with alkali, in a weight ratio of (A):(B) of from 5:1 up to 100:1, wherein said powder or granule contains at least 75% by weight of citrate (A), said process comprising the steps of (a) mixing the at least one alkali metal salt of citric acid (A) and the at least one (co)polymer (B) in the presence of water, (b) removing most of said water by spray-drying or spray granulation using a gas with an inlet temperature of at least 125° C.

Abstract: Aqueous formulation containing (A) at least one pigment or at least one dyestuff, (B) at least one dispersant selected from (B1) copolymers of at least one ethylenically unsaturated C4-C10-dicarboxylic acid and at least one C4-C20-olefin and their respective alkali metal salts and (B2) aromatic sulfonic acids and their respective alkali metal salts.(C) at least one chelating agent selected from MGDA, GLDA, IDS and citric acid and their respective ammonium and alkali metal salts. (D) water, wherein the concentration of the pigment (A) or dyestuff (A) is in the range of from 5 to 500 ppm, referring to the total aqueous formulation, and wherein the weight ratio of dispersant (B) to the pigment (A) or dyestuff (A), respectively, is in the range of from 1:5 to 3:1.
