DEFINITION

Classification: 516/13

The agent contains organic compound containing phosphorus or silicon:

(under subclass 10) Subject matter in which the colloid system making or stabilizing agent* contains an organic* compound which contains silicon or Phosphorus.

(1) 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.
