DEFINITION

Classification: 516/12

The agent contains organic compound containing halogen:

(under subclass 10) Subject matter in which the colloid system making or stabilizing agent* contains an organic* compound which contains halogen. d (1) d ( ) Note. Halogen may be ionic or covalent or complex. d (2) d ( ) Note. When classifying foam colloid systems, the agent should not be confused with the gas phase. The (colloid system making or stabilizing) agent is the component which tends to aggregate at the boundary between the gas phase and the liquid phase to facilitate or assist in the persistence of the system for the degree of time sufficient for its intended use. This subclass is not the proper location for foam colloid systems in which the only halogen containing compound is the propellant and/or gas phase.

(1) Note. Halogen may be ionic or covalent or complex.

(2) Note. When classifying foam colloid systems, the agent should not be confused with the gas phase. The (colloid system making or stabilizing) agent is the component which tends to aggregate at the boundary between the gas phase and the liquid phase to facilitate or assist in the persistence of the system for the degree of time sufficient for its intended use. This subclass is not the proper location for

foam colloid systems in which the only halogen containing compound is the propellant and/or gas phase.
