DEFINITION

Classification: 516/46

The agent contains organic compound containing oxygen:

(under subclass 38) Subject matter in which the colloid system making or stabilizing agent* contains an organic* compound which contains oxygen.

18+, for a similar colloid system making or stabilizing agent* used in foam colloid system.

20, for a similar colloid system making or stabilizing agent* used in organic* liquid continuous phase with organic* liquid discontinuous phase (e.g., oil-in-oil emulsion).

28+, for a similar colloid system making or stabilizing agent* used in organic* liquid continuous phase with inorganic* liquid discontinuous phase (e.g., water-in-oil emulsion).

31+, for a similar colloid system making or stabilizing agent* used in organic* liquid continuous phase with discontinuous phase primarily solid or semisolid.

39, for a similar colloid system making or stabilizing agent* where the organic* compound which contains oxygen is derived from a native precursor in the bituminous material* and it is subjected to an in situ reaction with an inorganic* alkaline agent.

72+, for a similar colloid system making or stabilizing agent* used in aqueous continuous phase with discontinuous phase primarily organic* liquid (e.g., oil-in-water emulsion). 77+, for a similar colloid system making or stabilizing agent* used in aqueous continuous phase with discontinuous phase primarily (nonbituminous) solid.
