Definitions
- the present invention relates to an air freshener.
- This application claims priority to Japanese Patent Application No. 2022-192183, filed on November 30, 2022, the entire contents of which are incorporated herein by reference.
- Air fresheners equipped with rod-shaped volatilization members for volatilizing fragrance and deodorant components into space are used.
- the main proposal is to impregnate a rod-shaped volatilization member with a fragrance composition in which fragrance components are dissolved in an organic solvent such as an isoparaffin solvent or a glycol ether solvent, and then volatilize the fragrance components from the volatilization member (e.g., Patent Documents 1 and 2).
- An aromatic composition comprising a fragrance composition containing a fragrance, water, and a water-soluble solvent; and a volatilization member at least partially immersed in the fragrance composition;
- the water-soluble solvent comprises at least one selected from the group consisting of 3-methoxy-3-methyl-1-butanol, 3-methoxy-1-butanol, 1-methoxy-2-butanol, 1-methoxy-2-propanol, and 3-methoxy-3-methyl-butyl acetate; and the volatilization member has a resin material.
- the chemical fibers include at least one selected from the group consisting of polyester fibers, polyurethane fibers, acrylic fibers, melamine fibers, polyimide fibers, polyamide fibers, phenol fibers, epoxy fibers, nylon fibers, vinylon fibers, polyacetal fibers, polyethylene fibers, polypropylene fibers, vinyl chloride fibers, and acetate fibers.
- the resin-based adhesive contains at least one selected from the group consisting of polyurethane resins and melamine.
- the present invention provides an air freshener that has excellent long-lasting fragrance.
- a numerical range expressed using “ ⁇ ” means a range that includes the numerical values written before and after " ⁇ " as the lower and upper limits.
- “A ⁇ B%” means A% or more and B% or less.
- the fragrance of the present invention comprises a fragrance composition containing a fragrance, water, and a water-soluble solvent, and a volatilization member at least partially immersed in the fragrance composition.
- the water-soluble solvent contains at least one selected from the group consisting of 3-methoxy-3-methyl-1-butanol, 3-methoxy-1-butanol, 1-methoxy-2-butanol, 1-methoxy-2-propanol, and 3-methoxy-3-methyl-butyl acetate
- the volatilization member has a resin material.
- fragrance In water-based fragrance compositions, where fragrance is solubilized in water using conventional surfactants, it is difficult to increase the fragrance content compared to conventional oil-based fragrance compositions, where fragrance is dissolved in an isoparaffin-based solvent without using surfactants. As a result, it is not possible to produce a strong fragrance. On the other hand, oil-based fragrance compositions do not have a sufficient fragrance compared to water-based fragrance compositions.
- the inventor came up with the idea of volatilizing a fragrance composition containing a fragrance, water, and a water-soluble solvent such as 3-methoxy-3-methyl-1-butanol using a volatilizing member having a resin material in order to improve the strength of the fragrance.
- the inventor discovered that the adoption of such a technical means had the unexpected effect of improving not only the strength of the fragrance, but also the durability of the fragrance's good fragrance, and thus completed the present invention.
- the fragrance composition contains a fragrance, water, and a water-soluble solvent.

本発明の芳香剤は、香料と水と水溶性溶剤とを含有する、香料組成物と、該香料組成物に少なくとも部分的に浸漬される揮散部材とを備える。該水溶性溶剤は、３－メトキシ－３－メチル－１－ブタノール、３－メトキシ－１－ブタノール、１－メトキシ－２－ブタノール、１－メトキシ－２－プロパノールおよび３－メトキシ－３－メチル－ブチルアセテートからなる群から選ばれる少なくとも１種を含み、かつ、該揮散部材は樹脂材料を有する。
The fragrance of the present invention comprises a fragrance composition containing a fragrance, water, and a water-soluble solvent, and a volatilization member at least partially immersed in the fragrance composition. The water-soluble solvent contains at least one selected from the group consisting of 3-methoxy-3-methyl-1-butanol, 3-methoxy-1-butanol, 1-methoxy-2-butanol, 1-methoxy-2-propanol, and 3-methoxy-3-methyl-butyl acetate, and the volatilization member has a resin material.
従来の界面活性剤を使用して香料を水に可溶化させた水性の香料組成物は、界面活性剤を使用せずに香料をイソパラフィン系の溶剤に溶解させた従来の油性の香料組成物と比較して香料の含有量を高くすることが困難である。そのため、強度の高い香りを出すことができない。一方、油性の香料組成物は水性の香料組成物と比較して香り立ちが充分ではない。
In water-based fragrance compositions, where fragrance is solubilized in water using conventional surfactants, it is difficult to increase the fragrance content compared to conventional oil-based fragrance compositions, where fragrance is dissolved in an isoparaffin-based solvent without using surfactants. As a result, it is not possible to produce a strong fragrance. On the other hand, oil-based fragrance compositions do not have a sufficient fragrance compared to water-based fragrance compositions.
かかる状況の下、本発明者は香りの強度の向上のために、香料と水と３－メトキシ－３－メチル－１－ブタノール等の水溶性溶剤とを含有する香料組成物を、樹脂材料を有する揮散部材によって揮散させることに想到した。かかる技術的手段を採用することで、香りの強度に加えて、芳香剤の香り立ちの良さの持続性が改善されるという予想外の効果が奏されることを本発明者は見出し、本発明を完成させた。
Under these circumstances, the inventor came up with the idea of volatilizing a fragrance composition containing a fragrance, water, and a water-soluble solvent such as 3-methoxy-3-methyl-1-butanol using a volatilizing member having a resin material in order to improve the strength of the fragrance. The inventor discovered that the adoption of such a technical means had the unexpected effect of improving not only the strength of the fragrance, but also the durability of the fragrance's good fragrance, and thus completed the present invention.
以下、芳香剤の実施形態を詳細に説明するが、これらの説明は本発明の実施形態の代表的な例であり、本発明はその要旨を超えない限りこれらの内容に限定されない。

The amount of volatilization of the fragrance composition due to capillary action can be controlled by the voids formed in the axial and radial directions. Each method will be described in detail below.
方法Ａ１では、加熱および／または乾燥による樹脂系接着剤の硬化の結果、複数の化学繊維同士を接着させることができる。化学繊維束の複数の繊維間にバインダー溶液を含浸させた後、樹脂系接着剤の硬化によって複数の化学繊維が部分的に結着される。その後、所望の長さにカットすることで化学繊維を有する揮散部材Ａ１が得られる。浸漬時に用いられるバインダー溶液の溶媒は、加熱および乾燥時に除去される。そのため、軸方向および径方向に複数の空隙が形成される。
In method A1, multiple chemical fibers can be bonded together as a result of the hardening of the resin-based adhesive by heating and/or drying. After the binder solution is impregnated between the multiple fibers of the chemical fiber bundle, the multiple chemical fibers are partially bonded together by the hardening of the resin-based adhesive. The chemical fibers are then cut to the desired length to obtain a volatilization member A1 having chemical fibers. The solvent of the binder solution used during immersion is removed during heating and drying. As a result, multiple voids are formed in the axial and radial directions.
方法Ａ１によって得られる揮散部材Ａ１においては、複数の化学繊維の間に樹脂系接着剤の硬化物が固着している。そのため、揮散部材Ａ１は複数の化学繊維と、該複数の化学繊維の間に固着した樹脂系接着剤の硬化物とを有する。
In the volatilization member A1 obtained by method A1, a cured resin-based adhesive is bonded between multiple chemical fibers. Therefore, the volatilization member A1 has multiple chemical fibers and a cured resin-based adhesive bonded between the multiple chemical fibers.

＜香りの官能試験および評価方法＞
各例の芳香剤の使用初期、使用中期、使用終期の香りの嗜好と強度をそれぞれ１３名のパネラーにより評価した。ここで、使用初期は、香料組成物の拡散を開始した直後である。使用中期は、容器内の香料組成物の３０％が減少したときである。使用終期は、容器内の香料組成物の７０％が減少したときである。
各時期が経過したとき芳香剤を１６．８ｍ３（幅２．７ｍ、奥行き２．７ｍ、高さ２．３ｍ）の密閉空間内に静置することで、香料成分を１時間空間内に揮散させた。その後、１３名のパネラーによって下記の基準で香りの嗜好と強度をそれぞれ評価し、その平均値を求めた。結果を表２に示す。 <Sensory test and evaluation method of aroma>
The fragrance preference and intensity of each example of the air freshener was evaluated by 13 panelists at the beginning, middle, and end of use. Here, the beginning of use is immediately after the fragrance composition starts to diffuse. The middle of use is when 30% of the fragrance composition in the container has decreased. The end of use is when 70% of the fragrance composition in the container has decreased.
After each period had elapsed, the air freshener was placed in an enclosed space of 16.8 m3 (2.7 m wide, 2.7 m deep, 2.3 m high) to allow the fragrance ingredients to evaporate into the space for one hour. After that, 13 panelists evaluated the fragrance preferences and strength according to the following criteria, and the average values were calculated. The results are shown in Table 2.
