Patent ID: 8916214

Claim:
A process for preparing a free-flowing powder containing, on a dry weight basis, per 100 parts by weight of the powder, at least 85 parts by weight of at least one deliquescent quaternary ammonium compound selected from the group consisting of choline chloride, choline bromide, choline hydroxide, choline carboxylate, choline carbonate, glycine betaine, and D,L-carnitine, wherein said process comprises drying an aqueous solution of said quaternary ammonium compound to achieve a solid product and by admixing at least one powdery salt of a medium to long chain fatty acid with a multivalent counter ion to said solid product in an amount of at least 0.1 part by weight per 100 parts by weight of said quaternary ammonium compound, and wherein, before drying said aqueous solution, at least one water-soluble salt of a medium to long chain fatty acid with a univalent counter ion is introduced into said aqueous solution, and at least 0.1 part by weight of said water-soluble salt is dissolved in said aqueous solution, per 100 parts by weight of said quaternary ammonium compound.
