DEFINITION

Classification: 516/118

The compound is polysiloxane which contains repeating -(OC nH 2n)- (i.e., repeating unsubstituted oxyalkylene):

(under subclass 117) Subject matter in which the organic* compound which contains silicon is polysiloxane which contains repeating -(OC nH 2n)- (i.e., repeating unsubstituted oxyalkylene, bonded directly to each other).

(1) Note. "Repeating -(OC nH 2n)-" means 2 or more, bonded directly to each other. Thus, this subclass requires at

least two ether linkages; monoether derivatives are located elsewhere.

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*.
