Abstract
1306895 Tobacco-smoke filters N R DI LUZIO 31 Aug 1971 [1 Oct 1970] 40615/71 Heading A2C N, N'-diphenyl-p-phenylenediamine is included in a filter to reduce the toxic effect of the filtered tobacco smoke on alveolar macrophages in the lung. The diamine, or preferably the diamine mixed with glutathione, may be used alone or mixed with other ingredients such as activated charcoal or impregnated into a filter carrier material such as cellulose acetate, paper, wood pulp, cotton, fibrous polyolefins, cellulose esters in fibrous or sheet form, regenerated cellulose, silica gel, alumina or tabocco.
