Note(s) An ingredient is always classified in the last appropriate place. [2] Ammonium salts are classified in the same way as metal salts. [2] In this sub-class it is desirable to add, in conformity with paragraph 61 of the Guide, after the double oblique stroke the symbols relating to complementary information concerning individual constituents of an invention unit which is already classified as such. This complementary information concerns the indication of additional compounding ingredients. [2]
