US 12,593,865 B2 · Member for flavor inhalation article, flavor inhalation article, phenol scavenger for flavor inhalation article, and method for producing flavor inhalation article

Abstract

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: H ⁢ S ⁢ P ⁡ ( phenol ) ≤ 8 , ( 1 ) V ⁢ p ≤ 0.2 Pa , ( 2 ) D ⁢ P ≥ 50 ⁢ ° ⁢ C . ( 3 ) 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.
