DEFINITION

Classification: 516/8.1

Precursor contains plural immiscible liquid phases (e.g., emulsion):

(under subclass 8) Subject matter in which the precursor to the colloid system contains 2 or more immiscible liquid phases, such as, an emulsion or non-emulsified immiscible liquids.

(1)

Note: The precursor refers to the colloid system and includes the propellant component(s) as well as the aerosol component(s).
