Description

【０００１】
【発明の属する技術分野】
本発明は、人体安全性の高い天然抽出物を利用し、速効性及び持続性を兼ねた消臭剤に関するものであり、特に自動車用のミスト式消臭スプレーに好適な消臭剤に関する。
【０００２】
【従来の技術】
消臭剤は手軽さからスプレーで用いられ、安全性と自然志向から天然物質系の消臭成分が主体となっている。天然物質系の成分は消臭作用が明確でない物もあるが、悪臭成分に対し中和、酸化、還元反応などの化学的消臭と考えられている。
【０００３】
この化学的消臭は、悪臭成分に対して次々と消臭成分が必要となることから、持続性のある消臭効果は望めない。
【０００４】
持続性の高い消臭剤もしくは脱臭剤として、触媒系脱臭剤や人工酵素が開発されているが、加工方法が限定されることや製品形態も限られるのが実情である。一方、芳香剤などは徐放を持たせるために、特開昭６２−５７４８６、や特開昭６３−１４４２号公報では鉱物粉体を用いること、特開平５−３９１０、同６−２８５３５８号、同９−２０８４０６号公報ではマイクロカプセルを使い持続性を持たせたものが開示されている。
【０００５】
【発明が解決しようとする課題】
鉱物やマイクロカプセルなどに液を封入し徐放させることは、手軽な噴霧式のスプレーではその構造からシリンダー部やピストン部が鉱物やマイクロカプセルにより傷つけられ作動不良が生じやすいことや、その傾向が顕著になるとシリンダー内でつまる、所謂つまり現象が起こり、所定量を噴霧することができないなどの解決すべき技術的課題がある。
【０００６】
また、無機多孔質微粒子は水溶液中では容易に沈殿し再分散が悪いことから、噴霧器から噴霧される溶液中に無機多孔質微粒子が均一に含まれないという解決すべき技術的課題があった。そこで、噴霧器内の部品と消臭剤の微粒子との摩擦から引き起こされる噴霧器の物理的な劣化やつまり現象を解消しうる消臭剤が要求されている。
【０００７】
【課題を解決するための手段】
上記課題を解決すべく請求項１に係る発明では、天然抽出物を含む消臭成分と無機多孔質微粒子を含有して消臭剤とした。
本発明によれば、天然抽出物を含む消臭成分とこの消臭成分を含んだ無機多孔質微粒子を含有する液を噴霧器により同時に噴射させることで、天然抽出物を含む消臭成分の速効的な効果と、無機多孔質微粒子から前記天然抽出物を含む消臭成分が徐放されることで持続性をもたせる効果の双方の効果を奏する。
【０００８】
請求項２に係る発明では、無機多孔質微粒子内には、前記天然抽出物を含む消臭成分が封入されてなり、経時的に天然抽出物が徐放されてなる消臭剤とした。
本発明によれば、天然抽出物を含む消臭成分を無機多孔質微粒子に封入することで、前記消臭成分が前記無機多孔質微粒子表面から徐々に揮発していき、次々と臭い成分に接触させることが可能となる。
【０００９】
請求項３に係る発明では、天然抽出物を含んだ消臭成分を長期間にわたり徐放させるために、前記無機多孔質微粒子の中空部を含んだ形状を、容積０．５〜１．５ｍｌ／ｇ、細孔径５０〜１５０オングストローム、比表面積２００〜６００ｍ²／ｇ、嵩密度０．２ｇ／ｃｍ³以下とした。
本発明によれば、無機多孔質微粒子に封入された天然抽出物を含む消臭成分の徐放期間が数日間継続する等、長期に亘って有効に作用するものである。
【００１０】
請求項４に係る発明では、請求項１乃至３に係る発明の無機多孔質微粒子径が、０．５〜１０μｍの範囲に存在するようにした。
本発明のように無機多孔質微粒子径が、０．５〜１０μｍの範囲に存在する場合には、天然抽出物を含んだ消臭成分と前記天然抽出物を封入した無機多孔質微粒子を含有した液を、臭い成分に対してミストにより接触させる噴霧器に充填して使用しても、噴霧器内の部品であるチューブ、止水部、ピストン、シリンダー、ノズルに無機多孔質微粒子との摩擦から引き起こされる物理的な劣化や、堆積を引き起こさない。したがって、天然抽出物を含む消臭成分とその消臭成分を含む無機多孔質微粒子を同時にミスト式噴霧器で噴射させても、噴霧状態の不良及び噴霧器内に無機多孔質微粒子が堆積し、噴霧できなくなるつまり現象が解消される。
【００１１】
請求項５に係る発明では、請求項１乃至４に係る発明の無機多孔質微粒子がシリカからなり、当該無機多孔質微粒子の含有量が、０．０１〜１％とした。
本発明によれば、無機多孔質微粒子が沈殿しても容易に分散させることが可能となり、噴霧器から噴射される液に均一に無機多孔質微粒子が含まれることから、ミスト式噴霧器に適した無機多孔質微粒子となる。
また、噴霧乾燥後における噴霧された物の外観に消臭剤の付着による粉を吹いたような外観の汚れが目立たないので、噴霧された物（ガラス、樹脂）は噴霧乾燥後に良好な外観が維持される。
【００１２】

BACKGROUND OF THE INVENTION
The present invention relates to a deodorant that uses a natural extract with high human safety and has both rapid efficacy and durability, and particularly relates to a deodorant suitable for a mist type deodorant spray for automobiles.
[0002]
[Prior art]
Deodorants are used as sprays because they are easy to use, and natural deodorant components are mainly used for safety and nature. Some of the natural substance components are not clearly deodorized, but they are considered to be chemical deodorization such as neutralization, oxidation, and reduction reaction for malodorous components.
[0003]
This chemical deodorization requires a deodorizing component one after another with respect to the malodorous component, and therefore a sustained deodorizing effect cannot be expected.
[0004]
Catalytic deodorizers and artificial enzymes have been developed as highly durable deodorants or deodorizers, but the reality is that processing methods are limited and product forms are also limited. On the other hand, in order to give sustained release to fragrances and the like, in Japanese Patent Laid-Open Nos. 62-57486 and 63-1442, mineral powders are used, Japanese Patent Laid-Open Nos. 5-3910 and 6-285358, Japanese Patent Application Laid-Open No. 9-208406 discloses a microcapsule that has durability.
[0005]
[Problems to be solved by the invention]
Enclosed liquids in minerals and microcapsules, etc., and releasing them slowly, can be caused by the structure of a simple spray-type spray because the cylinders and pistons are easily damaged by minerals and microcapsules. When it becomes noticeable, there is a technical problem to be solved such that a so-called phenomenon occurs in the cylinder, and a predetermined amount cannot be sprayed.
[0006]
Further, since the inorganic porous fine particles are easily precipitated and poorly redispersed in an aqueous solution, there is a technical problem to be solved that the inorganic porous fine particles are not uniformly contained in the solution sprayed from the sprayer. Therefore, a deodorant capable of eliminating the physical deterioration of the sprayer, that is, the phenomenon caused by the friction between the components in the sprayer and the fine particles of the deodorant is required.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, in the invention according to claim 1, a deodorant containing a natural extract and inorganic porous fine particles is used.
According to the present invention, the liquid containing the deodorant component containing the natural extract and the inorganic porous fine particles containing the deodorant component is simultaneously sprayed by the sprayer, so that the deodorant component containing the natural extract is rapidly effective. And the effect of giving sustainability by the sustained release of the deodorizing component containing the natural extract from the inorganic porous fine particles.
[0008]
In the invention according to claim 2, the deodorizing component containing the natural extract is enclosed in the inorganic porous fine particles, and the natural extract is gradually released over time.
According to the present invention, the deodorant component containing the natural extract is encapsulated in the inorganic porous fine particles, so that the deodorant component gradually evaporates from the surface of the inorganic porous fine particles, and contacts the odorous components one after another. It becomes possible to make it.
[0009]
In the invention according to claim 3, in order to release the deodorant component containing the natural extract over a long period of time, the shape including the hollow portion of the inorganic porous fine particles has a volume of 0.5 to 1.5 ml / g, pore diameter of 50 to 150 angstrom, specific surface area of 200 to 600 m ² / g, bulk density of 0.2 g / cm ³ or less.
According to the present invention, the deodorant component including the natural extract encapsulated in the inorganic porous fine particles acts effectively for a long period of time, such as a sustained period of several days.
[0010]
In the invention according to claim 4, the inorganic porous fine particle diameter of the invention according to claims 1 to 3 is in the range of 0.5 to 10 μm.
When the inorganic porous fine particle diameter is in the range of 0.5 to 10 μm as in the present invention, the deodorant component containing the natural extract and the inorganic porous fine particle enclosing the natural extract were contained. Even if the liquid is used in a sprayer that makes contact with odor components by mist, it is caused by friction with inorganic porous fine particles on the tube, water stop, piston, cylinder, nozzle that are parts in the sprayer. Does not cause physical deterioration or deposition. Therefore, even if the deodorant component containing the natural extract and the inorganic porous fine particles containing the deodorant component are simultaneously sprayed with a mist type sprayer, the sprayed state is poor and the inorganic porous fine particles accumulate in the sprayer and can be sprayed. That is, the phenomenon disappears.
[0011]
In the invention according to claim 5, the inorganic porous fine particles of the invention according to claims 1 to 4 are made of silica, and the content of the inorganic porous fine particles is set to 0.01 to 1%.
According to the present invention, it is possible to easily disperse the inorganic porous fine particles even if they are precipitated, and since the inorganic porous fine particles are uniformly contained in the liquid sprayed from the sprayer, an inorganic suitable for a mist type sprayer. It becomes porous fine particles.
In addition, since the appearance of the sprayed product after spray drying is not conspicuous, such as the appearance of dust sprayed with deodorant, the sprayed product (glass, resin) has a good appearance after spray drying. Maintained.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to examples. The embodiments of the present invention are not limited to these.
[0013]
【Example】
Example 1
FIG. 1 shows an outline of inorganic porous fine particles having a hollow, and FIG. 2 shows an outline of inorganic porous fine particles having no hollow portion. Using the inorganic porous fine particles and glass hollow bodies (Fuji Glass Balloon: partial class) shown in FIGS. 1 and 2, their particle diameters, operability, and spray state were compared. As a spray, Kawano resin trigger (TS01M) and Canyon (T9600) were used. After confirming the operability / spraying state for 50 to 100 times continuously, drying was performed for about one day in a thermostatic bath at 50 ° C., and finally sprayed about 1000 to 1500 times.
[0014]
The larger the particle size of the inorganic fine particles, the larger the trigger operability and the poor spray state, and 10 μm or less was preferable.
[0015]
[Table 1]

[0016]
(Example 2)
Transparent bottles suitable for each trigger were prepared for the inorganic porous composition and redispersibility in an aqueous solution, and compared with an internal volume of 300 ml. The aqueous solution is composed of 1 to 10% of two or more natural extracts composed of tea, strawberries, mugwort, perilla, etc., and 0.01 to 1% of inorganic porous fine particles.
After filling the aqueous solution into the container, the dispersibility of the inorganic porous fine particles was compared under the condition of being allowed to stand for several days to several months in a high-temperature bath at room temperature.
[0017]
It was confirmed that the inorganic porous fine particles do not cause aggregation by filling a sprayer with a liquid containing a deodorizing component containing a natural extract and inorganic porous fine particles and leaving the mixture for a long period of time. Further, although there is no difference in composition in the tendency of precipitation in an aqueous solution, high purity silica was preferable in view of redispersibility.
[0018]
[Table 2]

[0019]
(Example 3)
The composition of the inorganic porous fine particles was compared with the appearance of spraying powder after spray drying. As a spray, Kawano resin trigger (TS01M) and Canyon (T9600) were used. Using inorganic porous fine particles made of high-purity silica and ceramic balloons (main component silica, alumina: impurity iron, etc.), the appearance after spraying was seen at an addition amount of 0.01 to 1%.
[0020]
In the inorganic porous fine particles containing impurities such as high purity silica and iron, a difference in appearance after spray drying was confirmed.
[0021]
[Table 3]

[0022]
(Comparative Example 1)
The sustained release properties of inorganic porous microparticles encapsulating natural extracts such as tea, strawberry, mugwort and perilla are described. The inorganic porous fine particles had a composition of silica, a particle diameter of 0.5 to 10 μm, a pore diameter of 50 to 150 mm, and a pore volume of 1 to 1.5 ml / g.
[0023]
Using inorganic porous microparticles encapsulating natural extract as a sample, 2 g of this sample was attached to 1 g of polyester cotton, and prepared immediately, left at room temperature for 1 day, and left at room temperature for 1 week. Thus, a deodorizing effect test sample was obtained. Odor gas: ammonia and hydrogen sulfide.
[0024]
A test sample and 600 ml of odorous gas were enclosed in a tedlar bag, and the change in gas concentration after 3 hours of standing was observed. The concentration was measured with a detector tube. For comparison, a blank filled with gas in a Tedlar bag and a polyester cotton filled were prepared.
[0025]
As shown in No. 1 to No. 3, natural deodorant components such as tea, rice cake, mugwort, and perilla are encapsulated in inorganic porous microparticles, thereby maintaining a level of one week.
[0026]
[Table 4]

[0027]
[Table 5]

[0028]
[Table 6]

[0029]
(Comparative Example 2)
An example of the deodorizing performance of a deodorizing component composed of a natural extract such as tea, rice cake, mugwort and perilla is shown. An aqueous solution of 1 to 5% of a natural extract such as tea, strawberry, mugwort, perilla was used as a deodorization test solution. Odor gas: ammonia and acetaldehyde. 1000 ml of odorous gas was sealed in the Tedlar bag, and the test solution was added in small portions, and changes in gas concentration were observed within 3 minutes each. The concentration was measured with a detector tube. For comparison, a blank in which only a gas was sealed in a tedlar bag was prepared. The odorous gas can be quickly deodorized from No.1 and No.2.

[0032]
【The invention's effect】
As described above, according to the present invention, the liquid containing the deodorant component containing the natural extract and the inorganic porous fine particles containing the deodorant component is simultaneously sprayed by the sprayer, thereby removing the natural extract containing the natural extract. Both the fast-acting effect of the odor component and the effect of providing sustainability by the sustained release of the deodorizing component containing the natural extract from the inorganic porous fine particles are exhibited. In this case, even if the deodorant component containing the natural extract and the inorganic porous fine particles containing the deodorant component are simultaneously sprayed with a mist type sprayer, the poor spray state and the inorganic porous fine particles are deposited in the sprayer, It is excellent in that it is impossible to spray, that is, the phenomenon is eliminated.
