Proteins or derivatives thereof in solution, or together with other macromolecular compounds, or together with an inorganic or non-macromolecular organic additive are considered as a composition and are thus classified according to the rules of C08L. They are classified according to the mutual proportions by weight of only the macromolecular constituents, in particular according to the macromolecular constituent present in the highest proportion. If all the constituents are present in equal proportions, the composition is classified according to each of these constituents.

Compositions containing a proteins or derivatives thereof and an inorganic or non-macromolecular organic additive as compounding agent are not classified in C08K as indicated in the rules for C08L, but in the corresponding C08L subclass together with the corresponding Indexing Code(s) in C08K.

Ex.: Composition consisting of gelatine and glass fibres (filler) is classified in C08L 89/06 and C08K 7/14

The same rules apply to C09D and C09J.

Covalently or ionically crosslinked gels are classified in C08H as they are considered as protein derivatives per se.

  • If they are not crosslinked, then these gels are classified in the corresponding C08L group together with C08J 3/075 and an Indexing Code of the group C08J 2300/00-C08J 2399/00 (Please see the Rules of classification for subclass C08J).

Ex.: Hydrogel of collagen is classified in C08L 89/06, C08J 3/075 and C08J 2389/06.
