516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting, appropriate subclasses for colloid systems or agents for such systems or making or stabilizing such systems or agents, especially
20+, for primarily organic continuous liquid phase colloid system (e.g., water-in-oil emulsion, dispersion of paraffin wax), subclasses 38+ for bituminous material, coal, or Carbon dispersed in a continuous aqueous phase colloid system (e.g., asphalt, pitch, tar, paraffin wax), subclasses 77+ for colloid systems of colloid-sized solid phase dispersed in aqueous continuous liquid phase (e.g., synthetic ester-wax dispersion); in each case, when generically claimed or when there is no hierarchically superior provision in the USPC for the specifically claimed art; and in the case when otherwise provided for in Class 106, when containing no material other than that to produce or stabilize the dispersion (i.e., Class 516 takes all bituminous emulsions, even though claimed as coating or plastic compositions, when they include nothing more than is necessary to form or stabilize the emulsion).
