DEFINITION

Classification: 516/8

The continuous phase contains a propellant derived from nongaseous phase (e.g., liquified propellant, such as hydrocarbon, halogenated hydrocarbon, dimethylether; sorbed or dissolved CO 2):

(under subclass 6) Subject matter in which the continuous phase contains a propellant of which a significant, intended portion was derived from a non-gaseous (solid, liquid, gel, or supercritical) phase, such as, liquified propellant, such as hydrocarbon, halogenated hydrocarbon, dimethylether; adsorbed or dissolved CO 2; propellant imbued in gel.

(1)

Note: Subject matter found here includes compositions (and nominally recited cans or containers) for making aerosols which are propelled from the container through a valve system by the pressure of the propellant expanding into the ambient atmosphere where the propellant is formulated to coexist with a non-gaseous phase of itself which tends to permit delivery of the aerosol at a substantially constant pressure until the container is empty. Also located here are the propellants per se when their ultimate intended use is disclosed or known to be for such aerosol compositions.

(2)

Note: The propellant must derived from the non-gaseous phase, not merely coexist with non-gaseous discontinuous phase component(s).

141, Fluent Material Handling, With Receiver or Receiver Coacting Means,

3, for processes in which an aerosol type dispenser type receiver is filled by steps involving manipulation of the dispenser as an incident to or aid to refilling or filling the supply chamber (i.e., the material to be dispensed, powder or liquid, is dissolved in or carried by a vaporizing propellant which forms the charge of the dispenser).

222, Dispensing,

394+, for dispensers in which the material is caused to discharge from the container by fluids under pressure that directly contact the material to be dispensed, and subclass 635 for a pressurized aerosol container.

401, Coating Implements With Material Supply,

190, for a device including pressurized reservoir (e.g., aerosol device).

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

1.13, for a radionuclide containing composition containing aerosol, subclasses 43+ for an effervescent or pressurized fluid containing composition, subclasses 76.2+ for nonbody deodorizing substances which are evaporable, sublimable, or gas (e.g., deodorization of air, aerosol spray compositions, gels), and digest 1 for aerosol hair preparations.

426, Food or Edible Material: Processes, Compositions, and Products,

116, for a packaged or wrapped product having utility for dispensing or serving an aerosol, and subclass 235 for application of a gas, mist, smoke, or vapor to a food material under the influence of electrical or wave energy. 510, Cleaning Compositions for Solid Surfaces, Auxiliary Compositions Therefor, or Processes of Preparing the

Compositions, appropriate subclasses for claimed or solely disclosed cleaning compositions. 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 aerosol colloid systems include

120, for a composition for cleaning human scalp hair, scalp, or wig which is dispensed by release of pressurized gas, subclasses 133+ for a composition for cleaning human skin (especially subclass 140 for packaged in an aerosol dispenser), subclass 198 for a gas-propelled composition for removing heat-degraded food residue from solid surface, subclasses 276+ for cleaning compositions for textile material (e.g., laundry detergent) (particularly subclass 279 for gas-propelled composition (e.g., aerosol) for cleaning pile fabric or upholstery (e.g., carpet, rug)), subclasses 367+ for cleaning compositions with oxygen or halogen containing chemical bleach or oxidant component (particularly subclass 370 for liquid, paste, foam, or gel (e.g., slurry, aerosol composition, or package)), subclasses 395+ for a cleaning composition with a scrubbing or scouring component (e.g., containing an abrasive, cream, paste, gel, gas-propelled, slurry), and subclasses 405+ for liquid cleaning compositions, especially for chemically specified surfactants (particularly subclass 406 for gas-propelled).
