On the Question of Defining So-called Tobacco Smoke Condensate/Zur Frage der Begriffsbestimmung des Tabakrauchkondensats

It is correct to define as "condensate'' those vaporous organic products of reaction which arise in addition to the products of combustion carbon dioxide and water, when cigarettes are smoked, and which can condense when cooling and forming an aerosol of a liquid phase in a gaseous phase. This condensate is clearly defined in DIN 10 240 as "dry smoke condensate''. Reference to this composite substance as "tar'' must be rejected as it is incorrect and can lead to inaccurate assumptions regarding occurrence and composition.
