Abstract:
The present invention is directed towards a process for making a powder or granule containing (A) at least one chelating agent selected from methyl glycine diacetic acid (MGDA) and glutamic acid diacetate (GLDA) and iminodisuccinic acid (IDS) and their respective alkali metal salts, (B) at least one homo- or copolymer of (meth)acrylic acid, partially or fully neutralized with alkali, said process comprising the steps of (a) mixing the at least one chelating agent (A) and the at least one homo- or copolymer (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.
