A method for producing a stable dispersion of a non-aqueous, liquid phase and dispersed dicarboxylic acid salts, which comprises reacting an aliphatic dicarboxylic acid with a divalent metal salt in an aqueous solution to form a dicarboxylic acid salt and subsequently separating and drying said dicarboxylic acid salt, wherein said dried dicarboxylic acid salt is elutriated and disintegrated in a non-aqueous, liquid phase, until a stable dispersion is formed.
