ABSTRACT:
There is prepared a powdery anticaking agent for inorganic salts based on (A) an iron cyanide complex, (B) a water insoluble inorganic, inert, finely divided hydroxyl group containing material or a material able to form this in the production of the anticaking agent, (C) hydrophobizing and/or (D) hydrophilizing materials in which (A), (C) and/or (D) are employed on component (B) as a carrier together with (E) water in an amount of 20 to 50 weight percent, preferable 35 to 45 weight percent. The composition is prepared by intensively mixing the carrier (B) in the corresponding ratio in the dry state with the active materials at room temperature and then adding to this mixture so much water that the active components go into solution and as such are absorbed on the carrier and regulating the pH to 7 to 9, preferably 7 to 8.
