PT86814A - Safety cigarette mfr. process - involves spraying tobacco with alcohol to block effect of harmful substances - Google Patents

Abstract

Redried cut rag tobacco is directly sprayed with one or more pre-selected alcohols. These are capable, when the vapours are inhaled by the smoker, of inhibiting or blocking the selective localisation of at least one nitrosamine and/or a metabolite thereof in the smoker's tissues such as those of the epithelial lining of his lungs. An example of such an alcohol is cyclohexanol in an ethyl alcohol solution. After the alcohol solution has been sprayed on the tobacco, pref. as it tumbles in the cooler cylinder of the mechanised cigarette making line, and allowed to dry, the tobacco is made or machined in a conventional manner into the final cigarette, either filtered or unfiltered. The blocking alcohol is then efficiently heat released into the tobacco smoke stream as the cigarette is smoked, resulting in the desired blocking effect in the smoker, without noticeably altering the customary smoking experience and satisfaction.
