DEFINITION

Classification: 507/203

Contains organic component:

(under subclass 200) Compositions including a component having carbon therein and which is further characterized by the presence in the molecule of (a) two carbon atoms bonded together or (b) one atom of carbon bonded to at least one atom of hydrogen or halogen or (c) one atom of carbon bonded to at least one atom of nitrogen by a single or double bond, with the proviso that hydrocyanic acid, cyanogen, isocyanic acid, cyanamide, cyanogen halides, isothiocyanic acid, metal carbides, and graphite are excluded from being organic compounds.

(1) Note. Components or compositions thereof reciting heavy distillation products (i.e., bottoms or pitch) of an originally specified material are classified according to said original material unless said products are otherwise identified.

(2) Note. Examples of components included in this subclass which are not provided for below are petrolatum, paraffin, rubber, organometallic complexes, and other compounds devoid

of provided-for functional groups.

(3) Note. When a generic oil (e.g., mineral oil, fuel oil, etc.) is disclosed as part of a composition, the composition is classified according to the other components.

(4) Note. Chelated, complexed, and coordinated organic moieties with metal are considered to have some nonionic character in the bond between the metal and the organic moiety (i.e., there is usually some amount of electron sharing or donating). As such, these chelated, complexed, and coordinated metals are classified as if the metal is part of the compound.
