The "antibacterial deodorant" is not particularly limited, but is preferably a plant-derived component containing wood, bamboo vinegar, and/or essential oil.

The aforementioned "wood and bamboo vinegar" is a liquid extracted from trees and bamboo. The part of the tree or the bamboo as the raw material is not particularly limited, and the stem, the leaf, the root, and the stem, the leaf, and the root of the bamboo can be used as the material, and if it is a tree, the leaf and the root are preferable. If it is a wood vinegar extracted from the leaves and roots of trees, it contains almost no tar components or environmental pollutants such as benzopyrene.

Further, the type of the tree is not particularly limited, but preferably contains at least one of eucalyptus, fir, arborvitae and Japanese fir.

The method for producing the wood and the bamboo vinegar is not particularly limited. However, the wood and bamboo vinegar are preferably distilled and extracted from the leaves or roots of the trees or the stems of the bamboo by steam, and the antibacterial and deodorizing effect is particularly high.

The aforementioned "essential oil" is a liquid extracted from trees and bamboo. The part of the tree or the bamboo as the raw material is not particularly limited, and the stem, the leaf, the root, and the stem, the leaf, and the root of the bamboo can be used as the material, and if it is a tree, the leaf and the root are preferable. If it is a wood vinegar extracted from the leaves and roots of trees, it contains almost no tar components or environmental pollutants such as benzopyrene.

Further, the type of the tree is not particularly limited, but preferably contains at least one of eucalyptus, fir, arborvitae and Japanese fir.

The method for producing the essential oil is not particularly limited, but it is preferred that the leaves or roots of the trees or the stems of the bamboo are distilled and extracted with water vapor, and the antibacterial and deodorizing effect is particularly high.

Essential oil: wood and bamboo vinegar can be used separately as antibacterial and anti-odor agents. Essential oil: wood and bamboo vinegar are preferably mixed in a ratio of 1:8~12, more preferably 1:9~11.

The "antibacterial deodorant-containing layer" is a layer containing an antibacterial deodorant, and the material thereof is not particularly limited, but a fiber raw material in which an antibacterial deodorant is easily impregnated is preferable. In particular, a very fine synthetic fiber raw material is preferred. For example, a non-woven fabric made of a polyethylene synthetic fiber having a single fiber fineness of 0.1 to 0.2 denier is immersed in a polyurethane resin, and a raw material which is raised by a polishing treatment on the surface is suitably used. In the case of such a raw material, it is particularly easy to impregnate the antibacterial deodorant, and the obtained product has a high antibacterial and deodorizing effect, and the effect continues for a long time.

The antibacterial deodorant sheet of the present invention may be composed only of the "antibacterial deodorant-containing layer", but it is preferable to form an adhesive layer on one surface side of the antibacterial deodorant-containing layer. Thereby, it can be easily installed in the side supplies and daily life. Products and so on. For example, it can be easily used if it is attached to shoes, purses, handbags, car interior materials, clothes, refrigerators, trash cans, wall cabinets or lockers.

As the "adhesive layer", for example, a double-sided tape or the like can be used.

[Examples] (production) Antibacterial deodorant

The leaves and roots of the eucalyptus, the Chinese fir, the arborvitae, and the stem of the bamboo are mixed in a prescribed ratio, and the wood and bamboo vinegar are extracted by steam distillation. Further, the leaves and roots of the eucalyptus, the Chinese fir, the arborvitae, and the stem of the bamboo are mixed in a predetermined ratio, and the essential oil is extracted by distillation with steam.

Next, the wood and bamboo vinegar and the essential oil are mixed in a ratio of wood and bamboo vinegar: essential oil = 10:1 to obtain an antibacterial deodorant.

2. Antibacterial deodorant sheet
