DEFINITION

Classification: 424/600

INORGANIC ACTIVE INGREDIENT CONTAINING:

(under the class definition) Compositions in which the active ingredient is disclosed to be an element or an inorganic compound.

(1) Note. Anesthetic compositions which contain oxygen and an active anesthetic compound are classified with the active anesthetic compound. For example, a composition containing an ether and 02 is classified in Class 314 subclass 715 or its indents.

(2) Note. A life supporting gaseous mixture; e.g., 02 and He, etc., is classified in Class 514, subclass 789.

(3) Note. See the Glossary for the definition of the term "active ingredient".
