Hydromagnesite-magnesium hydroxide compositions which, when used as fillers in smoking article wrappers, significantly reduce the amount of sidestream smoke produced by the burning smoking article while providing the smoking article with good subjective characteristics.

Smoking article wrapper having filler of hydromagnesite/magnesium

Hydromagnesite-magnesium hydroxide compositions are prepared which, when used as fillers in smoking article wrappers, significantly reduce the amount of sidestream smoke produced by the burning smoking article while providing the smoking article with good subjective characteristics.

Methods and apparatuses for cleaning an electrical lighter are provided. A sleeve, e.g., ceramic or metal, surrounds the heater fixture, and a resistive heating element is in thermal proximity with the sleeve. The resistive heating element is either a dedicated element or the cigarette heating elements. The sleeve serves as a aerosol barrier and condensate accumulator to protect other components. Periodically, e.g., substantially contemporaneously with a battery recharge, the heating element is activated to thermally liberate condensates deposited on the sleeve during smoking and also heats, and thereby cleans, other components. Also, a cleaning element is optionally inserted into the cigarette receptacle of the electrical lighter or placed at the exit thereof to absorb, attract and/or catalytically break down the thermally liberated condensates. The sleeve also directs a desired flow path for drawn air within an electrical lighter toward the cigarette.

This invention provides smoking compositions which contain a novel .beta.-hydroxycarboxylate flavorant-release additive. Under cigarette smoking conditions, a combustible filler and/or paper wrapper additive such as calcium bis(2,2-diethyl-3-hydroxy-4-phenylmethylenedecanoate) pyrolyzes and releases .alpha.-hexylcinnamaldehyde as a volatile flavorant component of the cigarette smoke.

Smoking compositions containing an .alpha.-alkylcinnamaldehyde-release

This invention provides novel organic acids which exhibit utility as liquid ion exchanges suitable for use in an invention solvent extraction process. Illustrative of an invention organic acid is a compound corresponding to the formula: ##STR1## where each of R.sub.1 and R.sub.2 is a C.sub.3 -C.sub.16 branched alkyl group.

The invention relates to the use of co-crystalline magnesite/magnesium hydroxide compositions as fillers for smoking article wrappers. Smoking articles made with wrappers containing these compositions exhibit significantly reduced sidestream smoke and does not compromise subjective attributes.

Magnesite/magnesium hydroxide fillers for smoking article wrappers

This invention provides a class of nicotine analogs which as therapeutic agents exhibit tranquilizing effects in mammals. Illustrative of an invention nicotine analog is 3-[N-methyl-N-(3-aminopropyl)]aminomethylpyridine ##STR1## the nicotine analogs can exist in the form of acid addition salts.

Nicotine analogs

An improved smoking article wrapper which significantly reduces sidestream smike using magnesium carbonate in the form of magnesite as a filler. Smoking articles which employ the wrappers exhibit a significant reduction in sidestream smoke without adverse effect on subjective characteristics.

Magnesite composition filler for smoking article wrapper

This invention privdes novel heteroaromatic compounds, and smoking compositions which contain an invention heteroaromatic compound as a flavorant-release additive as illustrated by the following additive structure: ##STR1## Under typical cigarette smoking conditions, 2-isopropylpyrazine and acetophenone are released as pyrolysis products, and enhance the flavor and aroma of the mainstream and sidestream smoke.

Smoking compositions containing a heteroaromatic flavorant-release

This invention provides a novel class of nicotine analogs which as therapeutic agents exhibit tranquilizing effects in mammals. Illustrative of invention nicotine analogs are 1-(3-dimethylaminopropyl)-2-(3-pyridyl)pyrrolidine: ##STR1## and (R,S)-6-(N,N-dimethyl-3-aminopropyl)nicotine: ##STR2## The nicotine analogs can exist in the form of acid addition salts.

This invention provides tobacco and non-tobacco smoking compositions which contain a quaternary ammonium compound as a flavorant additive. In one of its embodiments this invention provides tobacco compositions which contain a quaternary ammonium flavorant additive such as ##STR1## Under smoking conditions the above illustrated pyridinium additive and its pyrolysis products flavor the mainstream smoke.
