DEFINITION

Classification: 516/1

CONTINUOUS GAS OR VAPOR PHASE: COLLOID SYSTEMS; COMPOSITIONS CONTAINING AN AGENT FOR MAKING OR STABILIZING COLLOID SYSTEMS; PROCESSES OF MAKING OR STABILIZING COLLOID SYSTEMS; PROCESSES OF PREPARING THE COMPOSITIONS (E.G., SMOKE, FOG, AEROSOL, CLOUD, MIST):

(under the class definition) Subject matter which is a (1) colloid system having a continuous gas or vapor phase, (2) composition containing an agent* for making or stabilizing such a system, (3) process of making or stabilizing such a system, or (4) process of preparing a composition containing an agent* for making or stabilizing such a system; such as smoke, fog, aerosol, cloud, mist, aerosolizing.

(1) Note. The discontinuous phase may be a solid, liquid, or a polyphasic material*, such as gels, emulsions.

(2) Note. As set forth in the class definition, included in this and indented subclasses are subcombination compositions, which includes those compositions which are substantially completely formulated except for performing a step thereon to form the colloid system, such as a chemical reaction, or a physical step. Examples of such step include spraying, aerosolizing, atomizing, heating, agitating, dissolving. Thus, a liquified composition in a pressurized container intended for creating a colloid-sized mist is proper for placement in this and indented subclasses, and as appropriate in other colloid system areas of this Class if the liquified composition is itself a colloid system.
