Incense sticks containing wood powder from trees belonging to the genus Thujopsis in the cypress family.

Description

This invention relates to incense sticks. Incense sticks, such as mosquito coils and Buddhist altar incense, contain combustion-supporting agents such as wood powder as a base material. Burning such incense can produce a pungent odor and smoky smell. To reduce the pungent odor of incense, it has been suggested to incorporate organic powders other than wood powder or to add specific fragrances. For example, Patent Document 1 describes a base material for incense sticks characterized by containing a powder obtained by drying and grinding the extract residue of green tea and/or semi-fermented tea as part of the raw materials. Furthermore, Patent Document 2 describes a mosquito coil containing a mosquito coil base, an insecticidal component, and a fragrance component, characterized in that the fragrance component includes an acetate ester, a butyric acid ester, and hexenol. Japanese Patent Publication No. 2008-137987International Publication No. 2017/110403 The incense sticks of the present invention contain wood powder from trees belonging to the genus Thujopsis in the family Cypressaceae. An example of a tree belonging to the genus Thujopsis in the family Cupressaceae is Japanese cypress (scientific name Thujopsis dolabrata). Japanese cypress is endemic to Japan and is sometimes referred to as Asunaro. In this specification, Japanese cypress includes Japanese cypress, Japanese cypress, and narrow-leaved Japanese cypress. In this specification, "wood powder" refers to wood processed into a powder. As wood powder from trees belonging to the genus Thujopsis in the family Cupressaceae, it may be made by processing trees belonging to the genus Thujopsis in the family Cupressaceae into a powder, or commercially available cypress powder may be used. The inventors have discovered that by incorporating wood powder from trees belonging to the genus Thujopsis in the cypress family into incense sticks, the pungent odor and smoky smell during combustion can be reduced. While the exact reason is unclear, it is believed that the inclusion of wood powder from trees belonging to the genus Thujopsis in the cypress family is related to the more efficient combustion of the incense sticks. In the incense sticks according to this embodiment, from the viewpoint of suitably obtaining the effect of reducing irritating odor and smoky odor, the proportion of wood powder from trees belonging to the genus Thujopsis in the cypress family is preferably 1% by mass or more, more preferably 3% by mass or more, and even more preferably 5% by mass or more. On the other hand, from the viewpoint of productivity, the proportion of wood powder from trees belonging to the genus Thujopsis in the cypress family is preferably 70% by mass or less, more preferably 50% by mass or less, and even more preferably 30% by mass or less. Wood powder is widely used as a combustion supporting agent in the base material of incense sticks from the viewpoint of flammability and moldability. According to the present invention, by using wood powder from trees belonging to the genus Thujopsis in the family Cypressaceae for part or all of the wood powder, the pungent odor and smoky smell when burning incense sticks can be reduced. In other words, with this manufacturing method, the pungent odor and smoky smell can be reduced without changing the total amount of wood powder from the existing blend, and therefore, compared to adding new organic powders other than wood powder, it does not require a review of manufacturing conditions such as the blending amount of each component, and is superior in terms of productivity. Furthermore, according to the present invention, since there is no need to blend specific fragrances, the pungent odor and smoky smell can be effectively reduced without compromising the traditional feel of incense sticks. However, this does not preclude the addition of organic powders or specific fragrances to the incense sticks according to the embodiments of the present invention, depending on the application, etc. The incense sticks according to this embodiment will be described in more detail below. The incense stick according to this embodiment includes, for example, a base material and a binder. The incense stick according to this embodiment may also contain active ingredients, additives, etc., as needed, depending on the intended use. (Base material) As a base material, a combustion regulating agent such as a plant-derived powder is preferably used. The base material (combustion regulating agent) mainly plays a role in imparting appropriate flammability and burning rate to the incense stick. In this embodiment, the wood powder of a tree belonging to the genus Thujopsis in the family Cupressaceae is included in the incense stick as a base material, for example. In the incense stick according to this embodiment, the base material may consist only of wood powder of a tree belonging to the genus Thujopsis in the family Cupressaceae, or it may be used in
