Product name Carbolinium for Coal tar creosote is a brownish-black/yellowishdark green oily liquid with a characteristic sharp odour, obtained by the fractional distillation of crude coal tars. Creosote is a mixture of several hundred, probably a thousand, chemicals, but only a limited number of them are present in amounts greater than 1%. There are six major classes of compounds in creosote: aromatic hydrocarbons, including polycyclic aromatic hydrocarbons (PAHs) and alkylated PAHs (which can constitute up to 90% of creosote); tar acids / phenolics; tar bases / nitrogen-containing heterocycles; aromatic amines; sulfur -containing heterocycles; and oxygen-containing heterocycles, including dibenzofurans. Creosote may be sold as diluted preparations, which may contain carrier oil or solvents. The composition and use of creosote areregulated in some countries; the regulations usually focus on the content of benzo[a]pyrene (BaP) and phenolics. Creosote is only slightly soluble in water and soluble in a variety of organic solvents. However, the physical and chemical properties of the individual components of creosote vary widely; some, for example, are highly soluble in water.
