The invention relates to a method for producing a cyristalline solid from glycine-N,N- diacetic derivatives (e.g. MGDA) with sufficiently reduced hygroscopicity, characterised in that at least one crystalline compound of formula (I) is provided as germ, and a spray granulation is produced with at least one compound of formula (I), preferably followed by a heat treatment. |
