Definitions

  • the present invention is concerned with the treatment of filters for tobacco smoke particularly cigarette filters, to limit the carcinogenic effect of the smoke passed by them to the consumer
  • One particular class of compounds falling within this category comprises the polycyclic aromatic hydrocarbons (PAH) which are converted by the cytochrome P450 enzyme system in the liver or the lung into oxygenated derivatives which have been shown to be carcinogenic
  • PAH polycyclic aromatic hydrocarbons
  • Pryor et al Science 220:425-427
  • the effect of free-radicals in the smoke has been extensively discussed, for example by Church and Pryor Environ Hea lth Perspect 64111-126 (1985)
  • GB-A-1044434 discloses the use of 2,4-monofurfuryl ⁇ dene sorbitol in cigarette filters to reduce the content of PAH in the smoke
  • EP-B-0 345 362 discloses the use of a particular type of free-radical inhibitor in skin cosmetics
  • the inhibitor in question is chosen from a group of furfurylidene derivatives of sorbitol. in particular 2.4-monofurfurylidene sorbitol and the tetra-O-alkyl derivatives thereof
  • a method for preparing 2,4-monofurfuryl ⁇ dene sorbitol was disclosed in US-A-3.383.279 comprising gradual addition of furfurol to acidified sorbitol thus forming the 2,4-O-furfuryl ⁇ dene derivative
  • a filter for tobacco smoke comprising means forming a passageway for smoke, characterised in that on a surface of the passageway arranged to contact the smoke there is provided an O-alkylated derivative of 2.4-monofurfuryl ⁇ dene sorbitol together with an antioxidant.
  • the O-alkylated derivative is desirably a C 1-5 -alkyl derivative, e.g. the methyl derivative, and the tetra-O-alkyl derivative is preferred.
  • the filter according to the invention is particularly represented by a cigarette filter, which may have any conventional construction arranged to provide a very large surface area in contact with the smoke passing through, for example packed filaments, open-cell foams, etc.
  • the free-radical inhibitor may be incorporated in the filter at any effective level, but typically at 2.5-30 mg per filter, especially about 5-20 mg, particularly when tetra-0-methyl 2,4-monofurfuryl ⁇ dene sorbitol is used
  • the filter also contains an antioxidant and the ratio by weight of the sorbitol derivative to the antioxidant is desirably from about 1.5:1 to 31, especially, about 2.1
  • Particularly preferred antioxidants comprise phenolic antioxidants such as tert-butyl-hydroxyanisole (BHA) or tert-butyl-hydroxytoluene (BHT). It appears that there is synergy between the sorbitol derivative and the antioxidant. and both components are necessary for maximum activity
  • the active components can be added to the cigarette filter by any convenient method, for example by dosing with a solution of the components and allowing the solvent to evaporate.
  • the packing material for the filter can be pre-impregnated with the active component before the filter is constructed.
  • the test methods were standard in the industry for the investigation of cigarette smoking and analysis of tobacco smoke
  • the cigarettes were "smoked" in a smoking machine conforming to the standard US Federal Trade Commission smoking protocol and the smoke was passed through a Cambridge filter, which was weighed before and after the smoking
  • the increase in weight of the filter is the total particulate matter (TPM) Nicotine was extracted from the filter by washing with alkaline methanol and estimated using gas chromatography using a nitrogen-phosphorus detection
  • the water content of the TPM was measured by extracting the filter with ethanol followed by gas chromatography with conductivity detection Tar is calculated by deducting the nicotine and water contents from the TPM
  • Benzo[ ⁇ ]pyrene (BaP) is taken as a representative carcinogen for tobacco smoke and was measured by HPLC analysis (with fluorescence detection) of a cyclohexane extract Cambridge filter

Abstract

Un filtre destiné à la fumée de tabac comprend un inhibiteur de radicaux libres, notamment un dérivé O-alkylé de 2,4-mono- fufurylidène sorbitol, ainsi qu'un antioxydant permettant de réduire la teneur en hydrocarbures aromatiques polycycliques de la fumée.
