DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oily aromatic substance evaporative material using an oily aromatic substance as a volatile component, and an oily acaricidal substance evaporative material using an oily acaricidal substance.

[0002]

2. Description of the Related Art Oily aromatic substances have been applied in various fields in the fields of fragrances, sterilization, insecticide and the like. In particular, in recent years, with the popularity of aromatherapy, attention has been paid to aromatic substances mainly composed of natural essential oil components. Conventionally, natural products having a bactericidal activity have been known, and in particular, essential oils of extracts obtained by steam distillation of natural products have been reported to have antibacterial properties (for example, J. Am .Pharm.Ass
oc., 45 (6), 378-381 (1956); J. Am. Pharm. Assoc., 47 (4), 25
0-254 (1958)).

[0003] In recent years, highly safe antibacterial and bactericides containing extracts from natural products as active ingredients have been reported.
For example, those using plant essential oils have been reported as being highly safe and capable of controlling ticks in particular (JP-A-63
Japanese Patent Application Laid-Open No. 6-40833) discloses a substance containing wood essential oil and the like that repels pests such as mites and cockroaches and has antibacterial and antifungal properties.
No.).

[0004] Various forms of these oily aromatic substances have been proposed as a method for evaporating the active ingredient. For example,
A non-aqueous synthetic resin liquid is kneaded with a gel-like substance obtained by absorbing a water-absorbent resin as an aqueous emulsion (Japanese Patent Laid-Open No. 4-139104) or a perfume powder composition obtained by mixing a liquid perfume with a powder. Perfumed powder compositions (JP-A-5-255691) and the like have been reported.

[0005] However, in any of the above, there is a problem that the volatilization of the active ingredient is insufficient because the exposed portion of the oil component to the surface is small, and a sufficient concentration of the active ingredient cannot be obtained.

[0006] Therefore, as a dosage form having a gap for retaining essential oil and a large surface area for efficiently volatilizing the active ingredient, a fiber sheet impregnated with the active ingredient (JP-A-4-29903) and the like are available. It is considered. These dosage forms have excellent volatility, but have a problem in that the essential oil retained is oily, so that bedding and clothes are stained by the exudation of the essential oil and uncomfortable due to stickiness.

[0007]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned conventional problems. Even if an oily aromatic substance is directly applied, there is no contamination of bedding or clothes due to exudation, and no discomfort due to stickiness of oily components. It is an object of the present invention to provide an oily aromatic substance vaporizing material and an oil miticide substance vaporizing material capable of volatilizing an effective ingredient to a sufficient concentration.
