(B) at least one alkali metal salt of a C10-C20 fatty acid,


in a weight ratio of (A):(B) of from 40:1 up to 1,000:1,
wherein said powder or granule contains at least 75% by weight of chelating agent (A),
said process comprising the steps of

(c) mixing the at least one chelating agent (A) and the at least one alkali metal salt of fatty acid (B) in the presence of water,
