Description
この出願は、2007年3月9日に出願された米国特許出願第60/905835号からの優先権を主張するものであり、この特許の内容全体が引用により本明細書に組み入れられる。
通気性は、単独での作用時には、主流煙の粒子相及び気相の両方を低減させるという点で望ましい特質を有する。
可塑剤としてトリアセチンを含むセルロースアセテート(CA)フィルタは、同じタールベースでフィルタなしシガレットと比較した場合、シガレットの主流煙からフェノール及びクレゾールを除去することが知られている。本リストリクタフィルタ設計は、フィルタ内のこのようなCAの量を約50%減少させる(例えば、従来の27mmフィルタのシガレット対このようなCAセグメントを10mmから14mm含む同等のリストリクタフィルタ)。CAが減少することにより、従来のCAフィルタと比較して単位タール(FTC)当たりフェノール及び単位タール(FTC)当たりクレゾールのレベルは明らかに増加するが、リストリクタフィルタ設計におけるフェノール/タール及びクレゾール/タール比は、同じタールベースにおけるフィルタなしシガレットのフェノール/タール及びクレゾール/タール比よりも依然として低い。この効果を抑えるために、グリセリンなどのエアロゾルフォーマをタバコカット充填剤に添加して、クレゾール/タール及びフェノール/タール比を補償及び減少させ、すなわちグリセリンの添加が、より少ない量の可塑化CAを含有する喫煙物品中のフェノール/タール及びクレゾール/タール比の相対的増加を抑える役目を果たすようにする。
