DEFINITION

Classification: 516/116

The agent contains both organic and inorganic (except water) materials (e.g., amine hydrophobized silica):

(under subclass 115) Subject matter in which the breaking (resolving) or inhibiting agent* contains both organic* and inorganic* (except water) materials*, such as, amine hydrophobized silica.

(1) Note. Included in this and indented subclasses are the inorganic* particles which are treated or coated with an organic* compound, by reaction or otherwise.

(2) Note. Indented subclasses have only been provided for organic* materials* containing an organic* compound containing Silicon, hence compound such as amine hydrophobized silica are proper for this subclass.

(3) Note. Materials* used as agents* which are impurely or crudely derived from plant or animal sources, are assumed to contain nitrogen-containing organic* compounds (i.e., the DNA and proteins), unless clearly separated out, such as cellulose, carbohydrate fractions, etc.

(4) Note. "Inorganic* (except water)" means water is not considered in the assessment of the composition of the inorganic* material*.

137, for similar subject matter related to breaking (resolving) or inhibiting of emulsions using an agent* which contains a solid material*, in which the material* contains both an inorganic* material* and an organic* material*.

139+, for similar subject matter related to breaking (resolving) or inhibiting of emulsions using an agent* which contains material* different from the primary components of both liquid phases of the colloid system, other than as provided for in subclasses 136+ (using an agent* which is solid surface functioning), and other than as provided for in subclass 140 (physically or chemically dissolving binding, or destroying or at least part of one liquid phase (other than the colloid system making or stabilizing agent*)); particularly subclass 141 for breaking (resolving) or inhibiting of aqueous-petroleum*, petroleum*-aqueous, aqueous-hydrocarbon, or hydrocarbon-aqueous emulsions using an agent* which contains a material* which is only inorganic*, and subclass 142 for breaking (resolving) or inhibiting of aqueous-petroleum*, petroleum*-aqueous, aqueous-hydrocarbon, or hydrocarbon-aqueous emulsions using an agent* which contains a material* which contains both organic* material* and inorganic* material*.
