USE OF INORGANIC OR NON-MACROMOLECULAR ORGANIC SUBSTANCES AS COMPOUNDING INGREDIENTS (pesticides, herbicides A01N; pharmaceuticals, cosmetics A61K; explosives C06B; paints, inks, varnishes, dyes, polishes, adhesives C09; lubricants C10M; detergents C11D; artificial filaments or fibres D01F; textile treating compositions D06) [2015‑07]
NOTE

  • The use of an ingredient for a specific polymer is classified by adding, in a C-set, to the group symbol of C08K, the subdivision of C08L 1/00 to C08L 99/00. Example: Polystyrene containing a carboxylic amide is classified in (C08K 5/20, C08L 25/06).
  • From April 2012, the use of an ingredient for a specific polymer is classified by adding, in a C-set, to the group symbol of C08K, the subdivision of C08L 1/00 to C08L 99/00. Example: Polystyrene containing a carboxylic amide is classified in (C08K 5/20, C08L 25/06).
  • In this subclass, in the absence of an indication to the contrary, an ingredient is classified in the last appropriate place.
  • In this subclass:
    • a mixture of ingredients is classified in the most indented group covering all the essential ingredients of the mixture, e.g.:
      {
      This note is applied only for mixtures with more than three essential ingredients. Mixtures with two or three ingredients are classified in the appropriate groups of C08K, e.g. a mixture of Al2O3, an ether and an amine is classified in C08K 3/22, C08K 5/06 and C08K 5/17
      }
    • ammonium salts are classified in the same way as metal salts
  • In this subclass, organic acid salts, alcoholates, phenolates or mercaptides are classified in the groups or subgroups of the parent compounds
  • The use of an ingredient for a specific polymer is classified by adding to the group symbol of C08K and separated therefrom by a "+" sign, the subdivision of C08L 1/00 to C08L 99/00.
    Example: Polystyrene containing a carboxylic amide is classified in C08K 5/20 + C08L 25/06
  • In this subclass are considered as compounding ingredients:
    • inert additives
    • radical crosslinking agents, e.g. peroxides, S-containing vulcanisation agents
    • coupling agents, i.e. compounds able to improve the adhesion between filler and macromolecule
    Are not considered as compounding ingredients:
    • chemical modifying or crosslinking agents which react via a condensation or addition mechanism (for C08B polymers C08B, for diene rubbers C08C 19/30, for other vinyl polymers C08F 8/00, for polysiloxanes C08L 83/00, for other C08G polymers C08G)
    • solvents or dispersion agents for making polymer solutions, emulsions or dispersions (C08J 3/02)
    • blowing agents (C08J 9/04)
WARNING

  • The following IPC group is not used in the CPC system. Subject matter covered by this group is classified in the following CPC groups:
    C08K5/5445 covered by C08K 5/544
