C08K
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)
NOTE
-
1.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). 2. 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). 3. 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.:
a mixture of a monohydric and a polyhydric alcohol C08K 5/05
a mixture of two polyhydric alcohols C08K 5/053
a mixture of an alcohol and an ether C08K 5/04
a mixture of an ether and an amine C08K 5/00
a mixture of an amine and a metal C08K 13/02
{
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+L25/06

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 C08F8/-, 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)
