摘要 |
A tobacco smoke filter comprising a porous substrate having a humectant, such as sodium pyroglutamate, dispersed therein to absorb moisture from the tobacco smoke thereby wet-filtering the tobacco smoke. The tobacco smoke filter can also comprise a porous substrate having microcapsules dispersed therein. The microcapsules can comprise a humectant such as sodium pyroglutamate. The microcapsules further preferably comprise one or more of methylcellulose, chlorophyllin and at least one vegetable oil. The tobacco smoke filter can also comprise a porous substrate having dry water and a porphyrin dispersed therein.
