FIELD: chemistry.
SUBSTANCE: invention relates to aminocarboxylates in solid form, having high storage stability and improved processing properties. Mixture in form of powder, granules or pellets includes: one or more aminocarboxylates, an additive selected from pyrogenic silicic acids and precipitated silicic acids, and optionally at least one solid additive in amount of up to 50 wt% in conversion to total amount of aminocarboxylate(s) and an additive(s), wherein weight ratio of aminocarboxylate(s) to additiv(s) is in range of 9:1 to 9,999:1.
EFFECT: invention makes it possible to provide free, partially neutralised or completely neutralised amino carboxylic acid in form of powders, granules or pellets, which have high physical stability and enable simple storage and processing by consumers.
