DEFINITION

Classification: 516/198

COMPOSITIONS CONTAINING A WETTING AGENT; PROCESSES OF WETTING; PROCESSES OF PREPARING THE COMPOSITIONS (E.G., SPREADING, PENETRATING, LEVELING):

(under the class definition) Subject matter which is a (1)

composition specialized and designed for or peculiar to use in wetting surfaces, (2) mere methods of using such compositions or of using compounds, per se, to perform a process of wetting (3) compositions useful in making compositions for wetting, or (4) methods of making the compositions; which includes uses described by such terms as spreading, penetrating, or leveling.

(1) Note. Agent* refers to the effective material*, energy, or means which acts in the given context. The term agent also includes subcombinations of an agent* composition, such as adjuvants*. (Thus, the term agent* may apply to a compound or composition which may not be fully functional for its stated context, or its functionality may be greatly enhanced by another component which is not present.) Note that although a compound can be an agent*, this class does not provide for compounds, per se. An agent* may be physical or energy.

8, Bleaching and Dyeing; Fluid Treatment and Chemical Modification of Textiles and Fibers. See the main class definition for the special use compositions classified therein, which include those compositions (or appropriate methods) which are claimed as specifically intended for such use, including colloid systems, wetting agents, subcombination compositions therefor, or appropriate methods (such as surfactant compositions, per se). Surfactants and colloid systems useful in Class 8 processes and compositions include, but are not limited to, wetting agents (e.g., with dyes), deaerating agents, foam suppressants, foam carriers (e.g., for dyeing, finishing, coating), see

400, 696 for dyeing compositions including wetting agents.

137, Fluid Handling,

13, for processes in which flow of fluent material is facilitated by the addition of material which affects the flow characteristics of the fluent material (e.g., suspending agent, viscosity reducing agent), or by the application of heat or other forms of energy. 162, Paper Making and Fiber Liberation, digest 3 for wetting agent.

205, Electrolysis: Processes, Compositions Used Therein, and Methods of Preparing the Compositions,

699, for electrolytic erosion of a workpiece for shape or surface change (e.g., etching, polishing, etc.) (process and electrolyte composition) wherein the electrolyte is held into contact with a portion of the workpiece surface by surface tension or capillary action.

424, Drug, Bio-Affecting and Body Treating Compositions,

70.19, for compositions which have topical nontherapeutic utility for treating the hair or scalp of the living body (e.g. grooming or adorning aids, tonics, rinses) which contain two or more surfactants (i.e. compounds that lower the surface or interfacial tension, including detergents, foaming or wetting agents, emulsifiers, solubilizers, or dispersants) which are either designated in the claims or are art recognized as such.

429, Chemistry: Electrical Current Producing Apparatus, Product and Process,

250, for apparatus having separator, retainer, spacer or materials for use for producing an electrical current in combination with a wetting agent or surfactant.

504, Plant Protecting and Regulating Compositions, appropriate subclasses for a plant stimulating or eradicating composition; including colloid systems, wetting agents, subcombination compositions therefor, or appropriate methods which are claimed as specifically intended for such use.

507, Earth Boring, Well Treating, and Oil Field Chemistry,

90, for compositions for addition to petroleum oils during transportation through conduits to prevent fouling or clogging of the conduits due to components of the petroleum oils precipitating out during the transportation (e.g., suspending agents, antiflocculants), subclasses 100+ for earth boring compositions which may contain colloid systems (e.g., dispersions, suspensions, emulsions) or wetting agents, subclasses 200+ for well treating compositions which may contain colloid systems (e.g., dispersions, suspensions, emulsions) or wetting agents.

510, Cleaning Compositions for Solid Surfaces, Auxiliary Compositions Therefor, or Processes of Preparing the Compositions, appropriate subclasses for claimed or solely disclosed cleaning compositions for cleaning or removing foreign matter from solid surfaces which may be wetting agents. Although various subclasses specifically provide for colloid systems or wetting agents, such subject matter may be placed based upon another criterion, such as its chemical constitution (i.e., as though it has no colloid system characteristic). Areas known to have documents related to wetting agents include: 364, for compositions for displacing organic liquid film from a solid surface which may include a wetting agent, subclass 365 for compositions for removing greasy or oily contaminant from a substrate which may include a wetting agent, subclasses subclass 514 for dishwasher rinse composition which may be a wetting agent.

514, Drug, Bio-Affecting and Body Treating Compositions, cross-reference art collection 946+ for subject matter

involving the increasing or enhancing of the rate or amount of active ingredient absorbed into the treated subject (e.g., skin, digestive tract).

520, Synthetic Resins or Natural Rubbers, appropriate subclasses for (1) synthetic resins, per se, or (2) resin containing compositions, the use or utility of which is not specifically provided for elsewhere. The subject matter of the Class 520 series is hierarchically superior to Class 516 for placement of ORs (original reference).

1, of Class 520 is the residual subclass for solid resin containing subject matter. See various subclasses in the 520 series of classes for aqueous or organic dispersions, latexes, or gels, of a polymer or natural or synthetic rubber, and methods of making or treating same.

523, Synthetic Resins or Natural Rubbers--Part of the Class 520 Series,

175, for liquid-solid drag reduction composition).
