USPC Class Details

Description: 516 colloid systems and wetting agents; subcombinations thereof; processes of / 516 colloid systems and wetting agents; subcombinations thereof; processes of/(113) compositions containing an agent for breaking (resolving) or inhibiting colloid systems; processes of breaking (resolving) or inhibiting colloid systems (e.g., gel breaking or inhibiting, coagulating, flocculating); processes of preparing the compositions (135) continuous liquid phase colloid system and discontinuous liquid phase (e.g., breaking an emulsion) (139) the agent contains material which is different from the primary components of both liquid phases of the emulsion colloid system (i.e., more than only diluting) (141) aqueous-petroleum, petroleum-aqueous, aqueous-hydrocarbon, or hydrocarbon-aqueous emulsion systems (143) the agent contains organic compound (146) the compound contains sulfoxy* (e.g., sulfonate terpene)
