Abstract
A synthetic material adapted for use in smoking products which, upon combustion, yields a lower amount of smokestream components which may be deleterious to the smoker than does tobacco, while having an acceptable smouldering rate and taste is prepared by the combination of a combustible material, such as carboxymethyl cellulose with a portion of a filler material.
Claims19
A smoking material comprising a combustible organic ingredient and a particulate inorganic filler, the major proportion of said combustible organic ingredient being a material selected from the group consisting of film-forming cellulose derivatives, their salts and mixtures thereof having the recurring anhydroglucose unit:
- ##EQU2## wherein at least one R is selected from the group consisting of lower alkyl, carboxy lower alkyl, hydroxy lower alkyl groups and mixtures thereof;
- and the remaining Rs are hydrogen and the average degree of substitution is from about 0.2 to 3.0;
- said major portion of said combustible organic ingredient and said particulate inorganic filler being present in a weight to weight ration of about 15:85 to 85:15.
A smoking material comprising a combustible organic ingredient wherein the major proportion of said combustible organic ingredient is sodium carboxymethyl cellulose and a particulate inorganic filler comprising perlite and dolomite said sodium carboxymethyl cellulose and said particulate filler being present in a weight to weight ratio of from about 85:15 to 15:85.
A smoking material comprising a combustible organic material and a particulate inorganic filler, said combustible organic material consisting essentially of one or more cellulose derivatives, their salts and mixtures thereof having the recurring anhydroglucose unit:
- ##EQU3## wherein at least one R is selected from the group consisting of lower alkyl, carboxy lower alkyl, hydroxy lower alkyl groups and mixtures thereof;
- and the remaining Rs are hydrogen and the average degree of substitution is from about 0.2 to 3.0;
- said combustible organic material and said particulate inorganic filler being present in a weight to weight ratio of from about 85:15 to about 15:85.
A smoking material comprising a combustible organic material and a particulate inorganic filler wherein said combustible organic material consists essentially of sodium carboxymethyl cellulose;
- said particulate inorganic filler comprises dolomite and perlite;
- and said combustible organic material and said particulate inorganic filler are present in a weight to weight ration of from about 85:15 to about 15:85.
A smokable product comprising a film in shred form comprising a combustible organic material and a particulate inorganic filler, said combustible organic material consisting essentially of one or more cellulose derivatives, their salts and mixtures thereof having the recurring anhydroglucose unit:
- ##EQU4## wherein at least one R is selected from the group consisting of lower alkyl, carboxy lower alkyl, hydroxy lower alkyl groups and mixtures thereof;
- and the remaining Rs are hydrogen and the average degree of substitution is from about 0.2 to 3.0;
- said organic material and said particulate inorganic filler being present in a weight to weight ration of about 15:85 to 85:15.
