DEFINITION

Classification: 204/567

Using modifying agent:

(under subclass 563) Process in which a gaseous, liquid, or solid material is used to change the physical or electrical characteristics of the emulsion or dispersion.

(1) Note. This subclass and the subclasses indented hereunder are intended to be interpreted broadly, including processes in which the modifying agent may be used merely as a carrier for one or more system constituents.
