An element for use in a smoking article, the element comprising a longitudinally extending core; wherein the longitudinally extending core comprises a filtering material; wherein the filtering material comprises a paper and/or other biodegradable material; and wherein the filtering material further comprising a hydrophobic material.

The present disclosure provides a smoking article including a filter portion and a cigarette column portion, and the filter portion and the cigarette column portion contain compositions that are identical to or different from each other. The compositions may include at least one selected from a group consisting of pyruvic acid, lactic acid, and citric acid.

A smoking article filter has a flavoring agent uniformly distributed in the smoking article filter, wherein the flavoring agent is in a solid state at room temperature and includes at least one natural wax and a flavoring component soaked into the at least one natural wax. Also provided are a smoking article including the smoking article filter and a method of manufacturing a smoking article.

There is provided an aerosol-generating article (10, 100), particularly for generating an inhalable aerosol upon heating, the aerosol-generating article (10, 100) comprising: an aerosol-generating substrate (12), a downstream section (14) extending from a downstream end of the aerosol-generating substrate (12) to a downstream end of the aerosol-generating article (10, 100); and an upstream section (16, 116) extending from an upstream end of the aerosol-generating substrate (10, 100) to an upstream end of the aerosol-generating article (10, 100), wherein the upstream section (16, 116) comprises an aversive agent.

Provided is a member for a flavor inhalation article that has sufficient selective filtering performance with respect to phenols and has exceptional storage stability. The member for a flavor inhalation article includes: a base member; and a phenol scavenger carried by the base member and comprising a substance satisfying formulae (1) to (3) below: $\begin{array}{cc}HSP\left(\mathrm{phenol}\right)8,& \left(1\right)\end{array}$$\begin{array}{cc}Vp0.2\mathrm{Pa},& \left(2\right)\end{array}$$\begin{array}{cc}DP50C.& \left(3\right)\end{array}$ where the HSP (phenol) is a distance between a Hansen solubility parameter of the substance and a Hansen solubility parameter of phenol, the Vp is a vapor pressure of the substance, and the DP is a dropping point of the substance.
