Abstract

A process for impregnating fibres of a tobacco smoke filter with physiologically and sensorially safe polycarboxylic acids or acidic salts thereof, in which the polycarboxylic acids which are crystalline at ambient and processing temperatures, or the acidic salts thereof, are suspended, in the form of fine particles having a number average particle size of less than 50 mu m, in an organic, liquid medium and the resulting suspension is applied to the fibres, leads to a filter material which permits an effective increase in the nicotine retention without adversely affecting the condensate yield and the resistance to drawing.
