Use of inorganic or non-macromolecular organic substances as compounding ingredients

**Definition:** This place covers:

**Glossary:** - Acyclic: The absence of a ring structure. - Carbocyclic: The presence of a ring or ring system where all ring members are carbons. - Condensed: The presence of two rings that share at least one ring member. - Heterocyclic: The presence of a ring or ring system wherein at least one ring member is not a carbon atom. - Inorganic compound: Compound devoid of a carbon atom and containing a non-metallic element, or a compound containing a carbon atom, and satisfying one of the following criteria: the compound cannot have a carbon atom having direct bonding to another carbon atom, or the compound cannot have direct bonding between a carbon atom and a halogen or hydrogen atom, or the compound cannot have direct bonding between a carbon and a nitrogen atom by a single or double bond.The following are exceptions to the above and are to be considered as inorganic compounds: compounds consisting of only carbon atoms (e.g. fullerenes), cyanogen, cyanogen halides, cyanamide, metal carbides, phosgene, thiophosgene, hydrocyanic acid, isocyanic acid, isothiocyanic acid, fulminic acid, unsubstituted carbamic acid, and salts of the previously mentioned acids and which contain the same limitations as to a carbon atom. - Macromolecular compound: Natural or synthetic (co)polymer or resin or rubber - Metal: Any element other than hydrogen, carbon, halogen (fluorine, chlorine, bromine, iodine and astatine), oxygen, nitrogen, sulfur, selenium, tellurium, phosphorus, silicon, boron, noble gases (helium, neon, argon, krypton, xenon and radon). - Organic compound: Compound satisfying one of the following criteria: at least two carbon atoms bonded to each other, or one carbon atom bonded to at least one hydrogen atom or halogen atom, or one carbon atom bonded to at least one nitrogen atom by a single or double bond.Exceptions to the above criteria are: compounds consisting of only carbon atoms (e.g. fullerenes), cyanogen, cyanogen halides, cyanamide, metal carbides, phosgene, thiophosgene, hydrocyanic acid, isocyanic acid, isothiocyanic acid, fulminic acid, unsubstituted carbamic acid, and salts of the previously mentioned acids; these exceptions are considered to be inorganic compounds for classification purposes. - Quinone: Compound derived from compounds containing a six-membered aromatic ring or a system comprising six-membered aromatic rings (which system may be condensed or not condensed) by replacing two or four >CH groups of the six-membered aromatic rings by >C=O groups, and by removing one or two carbon-to-carbon double bonds, respectively, and rearranging the remaining carbon-to-carbon double bonds to give a ring or ring system with alternating double bonds, including the carbon-to-oxygen bonds; this means that acenaphthenequinone or camphorquinone are not considered as quinones.
