DEFINITION

Classification: 516/55

The agent contains organic compound containing silicon :

(under subclass 53) Subject matter in which the colloid system making or stabilizing agent* contains an organic* compound which contains silicon.

13, 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).

23, 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.

38, for a similar subject matter (unless provided by an indented subclass of specifically provided for organic* compounds) used in bituminous-in-aqueous emulsions.

77+, for a similar colloid system making or stabilizing agent* used in aqueous continuous phase with discontinuous phase primarily (nonbituminous) solid.
