Combinations of cellulose acetate tow, filter plasticisers and medium molecular weight polyethylene glycols have been selected in order to minimise the benzo(a)pyrene content of smoke. This has been achieved without detriment to the taste characteristics of the smoke. The different plasticisers used in the manufacture of filters are glycerine triacetate, triethylene glycol diacetate (TEGDA), dimethoxymethyl phenalate, dimethylphenalate, or some combination of them. As a result of tests carried out in our studies, it has been concluded that TEGDA, compared to the other plasticisers, is a stronger absorber of benzo(a)pyrene. The most effective absorber of benzo(a)pyrene is obtained with TEGDA mixed with 30% polyethylene glycol having an average molecular weight of 200. Quantitative data will be presented in the paper.
