Title
(EN) LOW SIDESTREAM SMOKE CIGARETTE WITH COMBUSTIBLE PAPER HAVING MODIFIED ASH CHARACTERISTICS
(FR) CIGARETTE A FUMEE SECONDAIRE FAIBLE, A PAPIER COMBUSTIBLE PRESENTANT DES CENDRES MODIFIEES
Abstract
(EN)
A low sidestream smoke cigarette comprises a conventional tobacco rod (54), and a combustible treatment paper (56, 58) having a sidestream smoke treatment composition. The treatment composition comprises in combination, an oxygen storage and donor metal oxide oxidation catalyst and an essentially non-combustible particulate adjunct for said catalyst. Improvements are made in the treatment composition and/or the addition of metal oxides or carbonates thereto to improve ash characteristics.
(FR)
Une cigarette à fumée secondaire faible, selon l'invention, comprend une tige de tabac classique et un papier de traitement combustible présentant une composition de traitement de fumée secondaire. Ladite composition de traitement comprend un catalyseur d'oxydation d'oxydes métalliques de stockage et donneur d'oxygène combiné à un adjuvant particulaire sensiblement non combustible destiné audit catalyseur. Selon l'invention, des améliorations sont apportées à la composition de traitement et/ou à l'addition d'oxydes métalliques ou de carbonates afin d'améliorer les caractéristiques des cendres.
