摘要 |
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.
