DEFINITION

Classification: 516/20

Primarily organic continuous liquid phase (e.g., organic liquid emulsified in an organic liquid):

(under subclass 9) Subject matter in which the colloid system contains a primarily organic* continuous liquid phase, such as organic* liquid emulsified in an organic* liquid.

(1) Note. "Primarily organic*" means that 50% or more of that liquid phase is organic* material*, by weight, volume, or molecule.

(2) Note. Oil-in-oil colloid systems are proper for this subclass, there being no indented subclass providing for this subject matter.

905+, for a collection of art under the class definition which discloses a per se composition containing a colloid system making or stabilizing agent* (e.g., foaming, emulsifying, dispersing, gelling), i.e., a composition containing said agent* and lacking both dispersant* and dispersand*.

520, Synthetic Resins or Natural Rubbers, appropriate subclasses for (1) synthetic resins, per se, or (2) resin
