SOAPS (I.E., ALKALI-METAL SALTS OF WATER-INSOLUBLE FATTYACIDS OR OF ROSIN ACIDS):
(under the class definition) Compositions which include an alkali-metal (i.e., Li, Na, K, Rb, or Cs) salt of an unsubstituted or hydroxy-substituted, saturated or unsaturated, higher fatty acid, or of rosin (abietic) acid, which are of general utility and lack any shape or structure to adapt them for use as cleaning agents; or processes of preparing such compositions.
(1) Note. A higher fatty acid is a water-insoluble monocarboxylic acid having an acyclic chain of at least seven carbons attached directly to the carboxyl group by nonionic bonding.
(2) Note. The compositions in this class frequently include salts of mixtures of fatty acids derived from different natural sources, such as two or more vegetable or fish oils, animal fats, etc.
(3) Note. The compositions included herein are, for example, used in well-drilling fluids, used in lubricant compositions, combined with other components, or refined for use as detergents and the like.

510, Cleaning Compositions for Solid Surfaces, Auxiliary Compositions Therefor, or Processes of Preparing the Compositions, appropriate subclasses, particularly
152+, 447+, 481+, etc., for soap-containing cleaning compositions. 516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting, appropriate subclasses for subject matter relating to: colloid systems (such as sols*, emulsions, dispersions, foams, aerosols, smokes, gels, or pastes) or wetting agents (such as leveling, penetrating, or spreading); subcombination compositions of colloid systems containing at least an agent specialized and designed for or peculiar to use in making or stabilizing colloid systems; compositions and subcombination compositions specialized and designed for or peculiar to use in breaking (resolving) or inhibiting colloid systems; processes of making the compositions or systems of the class; processes of breaking (resolving) or inhibiting colloid systems; in each instance, when generically claimed or when there is no hierarchically superior provision in the USPC for the specifically claimed art; including those instances when a composition would otherwise be proper for this subclass (367.1).
554, Organic Compounds, appropriate subclasses, for higher fatty acid salts, per se.
