Aluminosilicate sab-15 as an additive for reducing the toxic and carcinogenic compounds present in tobacco smoke

Abstract

The invention relates to the use of the aluminosilicate SAB-15, or the acidic or sodic forms thereof, interchanged with Fe, Na, K, Ca, Ce, Zr, the oxides of Fe, Na, K, Ca, Ce, Zr, and mixtures of same as an additive for reducing the toxic and carcinogenic substances present in tobacco smoke.

1 . Use of aluminosilicate SAB-15, or the acidic or sodium forms thereof, interchanged with Fe, Na, K, Ca, Ce, Zr, the oxides of Fe, Na, K, Ca, Ce, Zr and mixtures thereof as an additive for reducing the toxic and carcinogenic substances present in tobacco smoke. 
     
     
         2 . Use according to  claim 1 , where the aluminosilicate SAB-15 has a spherical morphological shape, tubular morphological shape or rod shape. 
     
     
         3 . Use according to  claim 1 , where the aluminosilicate SAB-15 has a pore size comprised between 4-10 nm and a mesopore volume preferably greater than 2.2 cm 3 /g. 
     
     
         4 . Mixture comprising dry tobacco and aluminosilicate SAB-15, or the acidic or sodium forms thereof, interchanged with Fe, Na, K, Ca, Ce, Zr, the oxides of Fe, Na, K, Ca, Ce, Zr and mixtures thereof as an additive and not containing adhesive agents. 
     
     
         5 . Mixture according to  claim 4 , characterized in that the additive is at a concentration comprised between 0.5-10% by weight with respect to the dry tobacco. 
     
     
         6 . Mixture according to  claim 5 , characterized in that the additive is at a concentration comprised between 2-7% by weight with respect to the dry tobacco.
