Abstract
A tobacco smoke filter comprises a material selected from cotton-crepe, viscose, cellulose, cellulose acetate, cotton, crepe-paper, aluminium foil, asbestos, glass wool, synthetic fibres or protein fibres, and contains at least 5 per cent by weight of a polyhydric alcohol having not more than six hydroxyl groups. The filter may form a cigarette or cigar mouthpiece or may be for use in a tobacco pipe and the amount of polyhydric alcohol is preferably between 5 and 40 per cent by weight. In one embodiment a cigarette filter plug formed of cotton-crepe or viscose is dipped into an aqueous solution of propylene glycol and then spun in a centrifuge. Other examples of suitable polyhydric alcohols are commercial sorbitol, diethylene glycol, glycerol, dipropylene glycol, ethylene glycol, butylene glycol, trimethylene glycol, pinacol, methyl glycerol, tetrahydric alcohols such as pentoses and pentaerythritol, pentahydric alcohols such as hexose, dextrose, laevulose and arabinitol, and hexahydric alcohols such as sorbitol, mannitol, iditol and talitol. A mixture of two or more of the polyhydric alcohols may be used and the polyhydric alcohol may be applied to a continuous filter rod which is subsequently dried.
