  • Suitable coating material are nonionics, film-forming agents such as shellac, etc.
  • sodium dihydrogen phosphate as inorganic material it has been found advantageous to use shellac as a coating material, since sodium dihydrogen orthophosphate may be converted in an alkaline detergent powder into disodium monohydrogen orthophosphate, which has a low melting point (about 30 C.) and which may cause caking of the powder. Coating the sodium dihydrogen phosphate granules with shellac, dissolved in alcohol, prevents this.
