(under the class definition) Compositions which under the conditions of use are burned, usually incompletely, or which involve a chemical reaction serving to act as a force to project the material desired into the air as a smoke, mist, or aerosol, the particles of which must be of colloidal size or larger. This and indented subclasses also provide for processes which are no more than the mere use of the composition; e.g., burning the composition in the area to be treated.
(1) Note. Compositions which are disclosed to be evaporable, per se, to yield smoke or to act as fumigants when left open to the air with or without application of external heat are classified elsewhere on the basis of the ingredients of the composition. To be placed herein, the composition, per se, must contain at least one combustible ingredient or there must be disclosed a chemical reaction taking place as a result of which some ingredient, component, or reaction product in particular form is dispersed into the air.
(2) Note. A composition designed to be burned in order to produce an odorizing or deodorizing effect upon the atmosphere; e.g., incense, etc., is classified here.

40, for a candle with a wick.
43, for a composition in which a compressed gas or release, or a chemical reaction serves to produce bubbles or effervescence in liquid, or in which a pressurized fluid component which is part of a composition on release serves to project other components of the composition into the air as a foam or spray.
