Combustible heat source for smoking article and smoking article comprising same
The present disclosure provides a combustible heat source composition for a smoking article, that does not contain a binder and a combustion inhibitor, wherein the composition comprises 1 to 5 parts by weight of a polyhydric alcohol based on 100 parts by weight of the solid content. A smoking article to which a combustible heat source composed of the composition is applied is characterized by having excellent ignitability and combustibility.
1 . A combustible heat source composition for a smoking article, that does not contain a binder and a combustion inhibitor, wherein the composition comprises 1 to 5 parts by weight of a polyhydric alcohol based on 100 parts by weight of the composition,
wherein the composition comprises potassium nitrate and sugar as ignition accelerator, and
wherein the sugar is selected from the group consisting of sorbitol, xylitol, mannitol, maltitol, lactitol, erythritol, reduced palatinose, and reduced starch syrup.
2 . The combustible heat source composition of claim 1 , wherein the binder is one or more selected from the group consisting of carboxymethylcellulose, ammonium alginate, pectin, carrageenan, and guar gum, and the combustion inhibitor is calcium carbonate.
3 . The combustible heat source composition of claim 1 , wherein the polyhydric alcohol is contained in an amount of 1 to 3 parts by weight.
4 . The combustible heat source composition of claim 1 , wherein the polyhydric alcohol is glycerin or propylene glycol.
5 . The combustible heat source composition of claim 4 , wherein the polyhydric alcohol is propylene glycol.
6 . The combustible heat source composition of claim 1 , wherein the heat source is ignited within 30 seconds, and combustion continues for 140 seconds or more.
7 . A smoking article comprising a combustible heat source composed of the composition of claim 1 .
8 . The combustible heat source composition of claim 1 , further comprising one or more selected from the group consisting of graphite, aluminum powder, and charcoal.
