A cooling cigarette filter and a smoking product are provided. The cooling cigarette filter comprises a cooling section. The cooling section is provided with one or more channels connecting two ends of the cooling section, and an inner surface of each channel is coated with a cooling material. The cooling material comprises an inorganic phase change material and PEG, and the inorganic phase change material comprises at least one of Na2CO3.10H2O, CH3COONa.3H2O, CaCl2.4H2O, and Na2SO4.10H2O. The cooling cigarette filter has the advantages of ensuring the amount of smoke and lowering the temperature of the smoke entering the mouth, especially in the cooling section. Through the combination design of the structure of the cooling stick and the type and amount of the cooling material, the smoke can flow out of a smoke generation section rapidly and smoothly.

[Problem] The present invention provides a capsule that is capable of suppressing volatilization of a highly volatile capsule content through the capsule shell and that is breakable.

[Solution] A breakable seamless capsule for a smoking equipment, comprising a content containing an oily ingredient and a capsule shell for encapsulating said content, wherein: the capsule shell contains a polysaccharide; the thickness of the capsule shell is 60 μm or more; the volatilization content (VC) of the content after leaving the content to stand under an environment at a temperature of 25° C. and a relative humidity of 40% for 4 hours is 3.0 wt % or more with respect to the total weight of the encapsulated content; and the crush strength per diameter of the capsule is 3-8 N/mm. In one embodiment, the crush strength per diameter of the capsule is 3.5-8 N/mm. In another embodiment, the capsule shell does not contain gelatin.

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:

[00001]$\begin{array}{cc}HSP\left(\mathrm{phenol}\right)\le 8,& \left(1\right)\\ Vp\le 0.2\mathrm{Pa},& \left(2\right)\\ DP\ge 50°C.& \left(3\right)\end{array}$

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.

A process for producing a filter element suitable for use in smoking articles may include: embedding a bundle of cellulose acetate fibers with an aqueous suspension of polyhydroxyalkanoate (PHA) to obtain a wet bundle of the cellulose acetate fibers covered by the aqueous suspension of the PHA; shaping the wet bundle in a form of a continuous elongated element; heating the continuous elongated element to temperature greater than or equal to 140° C. and less than or equal to 180° C. for time sufficient to melt the PHA and to evaporate water from the continuous elongated element; cooling the heated continuous elongated element to obtain crystallization of the PHA; and cutting the so-obtained continuous elongated element into segments of predetermined length.
