Note(s)

  1. In this sub-class, an ingredient is classified in the last appropriate place. [2]
  2. Ammonium salts are classified in the same way as metal salts. [2]
  3. 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 a technical subject which is already classified as such. This complementary information concerns the indication of additional compounding ingredients. [2]
