Description
本発明は、界面活性剤の配合量が低減されており、且つ透明で外観性状が良好な芳香液に関する。また、本発明は、該芳香液の製造方法に関する。 The present invention relates to a fragrant liquid that has a reduced amount of surfactant and is transparent and has a good appearance. The present invention also relates to a method for producing the aromatic liquid.
室内空間や収納空間の臭気による不快感をなくし、快適な空間を生み出すために、香料を配合した芳香剤が広く使用されている(例えば、特許文献1参照)。芳香剤では、通常、揮散される香気の質や強さを調整するために、香料を水等の水性溶媒に分散させた芳香液が使用されている。このような芳香液に使用される香料は親油性を示すため、従来、芳香液の製造には界面活性剤の配合が不可避とされている。 In order to eliminate the discomfort due to the odor of the indoor space and the storage space and to create a comfortable space, a fragrance containing a fragrance is widely used (for example, see Patent Document 1). In the fragrance, a fragrance liquid in which a fragrance is dispersed in an aqueous solvent such as water is usually used in order to adjust the quality and strength of the odor to be volatilized. Since the fragrance | flavor used for such an aromatic liquid shows lipophilicity, the mixing | blending of surfactant is unavoidable conventionally for manufacture of an aromatic liquid.
しかしながら、界面活性剤は常温で揮発しないため、界面活性剤を配合した芳香液では、使用時間の経過と共に芳香液中の界面活性剤の濃度が上昇し、香料の揮散終了後には界面活性剤が残存するという欠点がある。このような使用後の界面活性剤の残存は、外観の悪化を招き、使用者に不快な印象を与えかねない。更に、使用時間の経過に伴う界面活性剤の濃度の上昇は、芳香液の減量速度を遅延させるため、香料の揮散性にも悪影響を及ぼすことが懸念される。特に、芳香液の揮散が、容器に収容された芳香液を吸上げて容器外部に芳香液を揮散させるための吸上揮散部材を用いて行われる場合には、使用後期における界面活性剤の濃度の上昇は、該吸上揮散部材における目詰まりを招き、ひいては香料の揮散を妨げることになる。 However, since the surfactant does not volatilize at room temperature, the concentration of the surfactant in the fragrance increases with the passage of time in the fragrance containing the surfactant. There is a drawback of remaining. Such residual surfactant after use may deteriorate the appearance and give the user an unpleasant impression. Furthermore, since the increase in the concentration of the surfactant with the passage of time of use delays the rate of weight loss of the fragrance, there is a concern that it may adversely affect the volatility of the fragrance. In particular, when the aroma liquid is volatilized using a wicking volatilization member for sucking up the aroma liquid contained in the container and volatilizing the aroma liquid outside the container, the concentration of the surfactant in the later stage of use The increase in the temperature causes clogging in the wicking volatilization member, and consequently prevents volatilization of the fragrance.
そこで、芳香液において界面活性剤の配合量の低減を図ることができれば、従来の芳香液における上記欠点が解消され、更には芳香液の製造コストの低減をも実現可能になる。しかしながら、芳香液において、単に界面活性剤の配合量を少なくすると、香料が水性溶媒に十分に分散できず、芳香液の白濁化を招き、外観性状を損なわせてしまう。そのため、界面活性剤の配合量を低減し、且つ外観性状が良好である芳香液について、未だ開発されていないのが現状である。 Therefore, if it is possible to reduce the blending amount of the surfactant in the fragrance liquid, the above-mentioned drawbacks in the conventional fragrance liquid can be solved, and furthermore, the production cost of the fragrance liquid can be reduced. However, if the amount of the surfactant is simply reduced in the fragrance liquid, the fragrance cannot be sufficiently dispersed in the aqueous solvent, causing the fragrance liquid to become cloudy and impairing the appearance properties. Therefore, the present situation is that the aromatic liquid which reduces the blending amount of the surfactant and has good appearance properties has not been developed yet.
本発明は、界面活性剤の配合量が低減され、使用後期においても芳香液の減量速度が安定に保たれており、且つ透明で外観性状が良好な芳香液を提供することを目的とする。 An object of the present invention is to provide a fragrant liquid that is reduced in the blending amount of the surfactant, maintains a stable reduction rate of the fragrance liquid even in the later stage of use, and is transparent and has good appearance properties.
本発明者らは、上記課題を解決すべく鋭意検討したところ、芳香液において、香料1重量当たり界面活性剤を0.4〜1重量部の比率を充足させ、且つ透明な芳香液に調整することによって、界面活性剤の配合量を低減して、使用後期においても芳香液の減量速度を安定に保つことが可能であり、且つ透明で外観性状が良好な芳香液を提供できることを見出した。本発明は、かかる知見に基づいて、更に検討を重ねることにより完成したものである。 The present inventors have intensively studied to solve the above problems, and in the aromatic liquid, the ratio of 0.4 to 1 part by weight of the surfactant per 1 part of the fragrance is satisfied, and is adjusted to a transparent aromatic liquid. As a result, it was found that the blending amount of the surfactant can be reduced, and the weight loss rate of the aromatic liquid can be kept stable even in the later stage of use, and a transparent aromatic liquid with good appearance properties can be provided. The present invention has been completed by further studies based on this finding.

本発明の芳香液は、使用後期においても芳香液の減量速度を安定に保つことができ、使用前期から後期に亘って均質な香気を放つことができる。また、本発明の芳香液は、界面活性剤の配合量が低減されており、使用後の残存物の量が低減されているため、使用者の満足度を高めることもできる。更に、本発明の芳香液は、界面活性剤の配合量が低減されているため、原料コストを低減できるという製造上の利点もある。 The fragrance liquid of the present invention can stably maintain the rate of weight loss of the fragrance liquid even in the later period of use, and can release a homogeneous fragrance from the first period to the latter period of use. Moreover, since the compounding quantity of surfactant is reduced and the quantity of the residue after use is reduced, the aromatic liquid of this invention can also raise a user's satisfaction. Furthermore, since the blending amount of the surfactant is reduced, the fragrance liquid of the present invention has a manufacturing advantage that raw material costs can be reduced.
また、本発明の芳香液は、透明であり、外観性状が良好であるので、消費者に対して意匠的観点からも満足感を与えることができる。 Moreover, since the fragrance liquid of the present invention is transparent and has a good appearance, it can give satisfaction to the consumer from a design viewpoint.
更に、本発明の芳香液が、吸上揮散部材を備えた容器に収容され、液状芳香剤として使用される場合には、使用後期であっても、該吸上揮散部材における界面活性剤が原因となって起きる目詰まりが生じ難いため、芳香液の減量速度が減弱しない。そのため、使用後期に容器に残存する芳香液の揮散性を高めるために、容器を振盪することにより吸上揮散部材に含浸させる芳香液を増加させる必要がないため、使用者にとっては不便性を感じずに使用することができる。 Furthermore, when the fragrance liquid of the present invention is contained in a container equipped with a wicking volatilization member and used as a liquid fragrance, the surfactant in the wicking volatilization member is a cause even in the later stage of use. Since clogging that occurs is difficult to occur, the rate of weight loss of the fragrance does not decrease. Therefore, in order to increase the volatility of the aromatic liquid remaining in the container in the later stage of use, it is not necessary to increase the aromatic liquid impregnated in the wicking volatilization member by shaking the container. Can be used without.
本発明の芳香液は、香料1重量当たり界面活性剤を0.4〜1重量部の比率で香料及び界面活性剤を含有し、且つ透明であることを特徴とするものである。 The aromatic liquid of the present invention is characterized in that it contains a fragrance and a surfactant in a ratio of 0.4 to 1 part by weight of the surfactant per 1 fragrance and is transparent.

<Nanoemulsion method>
In order to prepare the fragrance liquid of the present invention by the nanoemulsification method, the mixture of the fragrance and the surfactant and, if necessary, other ingredients are added to an aqueous solvent, and this is subjected to a known nanoemulsion treatment. do it. The nanoemulsion treatment can be performed, for example, by a known treatment method such as ultrasonic treatment, high-pressure emulsification treatment, high-speed swirling thin film treatment, or high shear type dispersion treatment. Among these nanoemulsion treatment methods, ultrasonic treatment and high-pressure emulsification treatment are preferable because they are excellent in physical shearing action and can efficiently prepare a nanoemulsion-type aromatic liquid.
これらのナノエマルジョン処理は、1種の処理方法を単独で実施してもよく、また2種以上の処理方法を組み合わせて実施してもよい。 These nanoemulsion treatments may be carried out by one kind of treatment method alone or in combination of two or more kinds of treatment methods.
ナノエマルジョン処理条件については、芳香液の組成、芳香液に備えさせる透明度、処理方法の種類等に応じて適宜設定すればよい。例えば、1Lの芳香液を超音波処理によって調製する場合であれば、例えば、出力50〜600W、周波数10〜30KHz及び振幅10〜200μmの超音波振動を1〜30分間程度負荷すればよい。また、例えば、高圧乳化処理であれば、例えば20〜40℃の温度条件下で5〜150MPaの圧力を負荷すればよい。 About nanoemulsion processing conditions, what is necessary is just to set suitably according to the composition of an aromatic liquid, the transparency provided to an aromatic liquid, the kind of processing method, etc. FIG. For example, if 1 L of aromatic liquid is prepared by ultrasonic treatment, for example, an ultrasonic vibration with an output of 50 to 600 W, a frequency of 10 to 30 KHz, and an amplitude of 10 to 200 μm may be applied for about 1 to 30 minutes. Further, for example, in the case of high-pressure emulsification treatment, a pressure of 5 to 150 MPa may be applied under a temperature condition of 20 to 40 ° C., for example.
ナノエマルジョン化法により製造される芳香液は、香料成分が微細化して水性溶媒に分散し、更には前述する回折/散乱光強度をも充足することにより、透明な外観性状を備えることが可能になっている。 The fragrance liquid produced by the nanoemulsification method can be provided with a transparent appearance by making the fragrance component finer and dispersing in an aqueous solvent and further satisfying the above-mentioned diffraction / scattered light intensity. It has become.
<濃縮化法>
濃縮化法によって本発明の芳香液を調製するには、香料、界面活性剤、及び水性溶媒(芳香液に配合される水性溶媒の一部)を混合して濃縮混合液を調製し、該濃縮混合液を水性溶媒(残りの水性溶媒)と混合すればよい。このように、2段階に分けて、水性溶媒を香料と混合することによって、乳化処理等の特段の処理を行わなくても、白濁することなく透明な外観を備える芳香液を調製することができる。濃縮化法による本発明の芳香液の製造は、具体的には、以下の手順に従って実施される。
<Concentration method>
In order to prepare the fragrance liquid of the present invention by the concentration method, a fragrance, a surfactant, and an aqueous solvent (a part of the aqueous solvent mixed in the fragrance liquid) are mixed to prepare a concentrated mixed liquid, and the concentrated liquid What is necessary is just to mix a liquid mixture with an aqueous solvent (remaining aqueous solvent). In this way, by mixing the aqueous solvent with the fragrance in two steps, an aromatic liquid having a transparent appearance can be prepared without clouding without performing a special treatment such as an emulsification treatment. . Specifically, the production of the aromatic liquid of the present invention by the concentration method is carried out according to the following procedure.
まず、香料1重量当たり界面活性剤が0.4〜1重量部の比率を満たし、且つ香料と界面活性剤の合計量100重量部当たり水性溶媒が100〜600重量部となる比率を充足するように、香料、界面活性剤、及び水性溶媒を混合することにより、香料濃縮液を調製する(第1工程)。即ち、本第1工程では、芳香液に配合される香料の全量、芳香液に配合される界面活性剤の全量、及び芳香液に配合される水性溶媒の一部を混合することにより、香料濃縮液を調製する。このように香料と界面活性剤を高濃度となるように水性溶媒に混合することによって、乳化処理等の特段の処理を行わなくても、白濁することなく透明な外観を備える香料濃縮液を得ることができる。本第1工程において、香料と界面活性剤の合計量と水性溶媒の混合比については、前述する比率を充足すればよいが、より透明性の高い芳香液を製造するという観点からは、香料と界面活性剤の合計量100重量部当たり水性溶媒が、好ましくは100〜500重量部、更に好ましくは150〜300重量部が例示される。 First, the surfactant satisfies the ratio of 0.4 to 1 part by weight per fragrance and the ratio of the aqueous solvent to 100 to 600 parts by weight per 100 parts by weight of the total amount of fragrance and surfactant is satisfied. In addition, a fragrance concentrate is prepared by mixing a fragrance, a surfactant, and an aqueous solvent (first step). That is, in the first step, the fragrance concentration is achieved by mixing the total amount of the fragrance blended in the fragrance liquid, the total amount of the surfactant blended in the fragrance liquid, and a part of the aqueous solvent blended in the fragrance liquid. Prepare the solution. In this way, by mixing the fragrance and the surfactant with an aqueous solvent so as to have a high concentration, a fragrance concentrate having a transparent appearance without being clouded can be obtained without performing a special treatment such as an emulsification treatment. be able to. In the first step, the total amount of the fragrance and the surfactant and the mixing ratio of the aqueous solvent may satisfy the above-described ratio, but from the viewpoint of producing a more transparent fragrance, The aqueous solvent is preferably 100 to 500 parts by weight, more preferably 150 to 300 parts by weight per 100 parts by weight of the total amount of the surfactant.
また、本第1工程において、香料、界面活性剤、及び水性溶媒の混合順については、特に制限されないが、透明性の高い香料濃縮液を得、ひいては最終的に製造される芳香液の透明性も高めるという観点から、まず香料と界面活性剤を混合し、香料と界面活性剤の混合液と水性溶媒を混合することが望ましい。 In the first step, the mixing order of the fragrance, the surfactant, and the aqueous solvent is not particularly limited, but a highly transparent fragrance concentrate is obtained, and finally the transparency of the aromatic liquid to be finally produced is From the viewpoint of increasing the fragrance, it is desirable to first mix the fragrance and the surfactant, and then mix the mixture of the fragrance and the surfactant with the aqueous solvent.
次いで、前記第1工程で得られた香料濃縮液と水性溶媒を混合することにより、芳香液を調製する(第2工程)。このように、第1工程で得られた香料濃縮液を、水性溶媒と混合することによって、超音波処理、高圧乳化処理等の特段の処理を要することなく、白濁のない透明な外観を備える芳香液を製造することができる。また、香料濃縮液と水性溶媒の混合液の組成が本発明の芳香液の組成となるので、本第2工程において、香料濃縮液と混合される水性溶媒の量については、芳香液に配合される水性溶媒の全量から上記香料濃縮液で配合された水性溶媒の量を除いた分に相当する量(残りの水性溶媒)に設定される。 Next, an aromatic liquid is prepared by mixing the fragrance concentrate obtained in the first step and an aqueous solvent (second step). In this way, the fragrance concentrate obtained in the first step is mixed with an aqueous solvent, so that no special treatment such as ultrasonic treatment or high-pressure emulsification treatment is required, and a fragrance having a transparent appearance without white turbidity. A liquid can be produced. In addition, since the composition of the mixture of the fragrance concentrate and the aqueous solvent becomes the composition of the fragrance liquid of the present invention, the amount of the aqueous solvent mixed with the fragrance concentrate in the second step is blended in the fragrance liquid. It is set to an amount (remaining aqueous solvent) corresponding to the amount obtained by subtracting the amount of the aqueous solvent blended with the fragrance concentrate from the total amount of the aqueous solvent.
また、本発明の芳香液に、香料及び界面活性剤以外に、他の配合成分を配合する場合には、その添加時期は当該配合成分の極性に応じて適宜設定すればよい。例えば、他の配合成分として油性成分を配合する場合、前記第1工程の段階で配合することにより香料濃縮液中に添加することが望ましい。また、他の配合成分として水溶性成分を配合する場合、前記第1及び2工程のいずれの段階で添加してもよい。 Moreover, what is necessary is just to set the addition time suitably according to the polarity of the said compounding component, when mix | blending other compounding components other than a fragrance | flavor and surfactant in the aromatic liquid of this invention. For example, when an oil component is blended as another blending component, it is desirable to add it to the fragrance concentrate by blending at the stage of the first step. Moreover, when mix | blending a water-soluble component as another compounding component, you may add in any step of the said 1st and 2 processes.
濃縮化法により製造される芳香液は、前述する回折/散乱光強度を充足することにより、透明な外観性状を備えることが可能になっている。 The aromatic liquid produced by the concentration method can be provided with a transparent appearance by satisfying the diffraction / scattered light intensity described above.
<複合法>
複合法によって本発明の芳香液を調製するには、前述する濃縮化法により芳香液を調製し、得られた芳香液を更に前述するナノエマルジョン処理に供すればよい。このように濃縮化法とナノエマルジョン処理を組み合わせて実施することにより、一層透明性が高い芳香液を製造することが可能になる。複合法で使用されるナノエマルジョン処理としては、前述する処理方法であればよいが、芳香液の透明性をより一層向上させるという観点から、好ましくは超音波処理及び高圧乳化処理、更に好ましくは超音波処理が挙げられる。
<Composite method>
In order to prepare the fragrance liquid of the present invention by the composite method, the fragrance liquid is prepared by the concentration method described above, and the obtained fragrance liquid is further subjected to the nanoemulsion treatment described above. As described above, by performing the combination of the concentration method and the nanoemulsion treatment, it becomes possible to produce an aromatic liquid having higher transparency. The nanoemulsion treatment used in the composite method may be any of the treatment methods described above, but from the viewpoint of further improving the transparency of the fragrance liquid, preferably ultrasonic treatment and high-pressure emulsification treatment, more preferably ultra Examples include sonication.
複合法により得られる本発明の芳香液は、香料の粒径がより細かい状態で分散しており、更に前述する回折/散乱光強度についてもより低い値を示し、透明性が一層向上している。また、複合法により製造される本発明の芳香液は、より一層の界面活性剤の配合割合の低減が可能であり、しかも外観性状の保存安定性の点でも卓越しているという利点がある。 The aromatic liquid of the present invention obtained by the composite method is dispersed in a state in which the particle size of the fragrance is finer, and further shows a lower value for the above-mentioned diffraction / scattered light intensity, and the transparency is further improved. . In addition, the aromatic liquid of the present invention produced by the composite method has an advantage that it is possible to further reduce the blending ratio of the surfactant and is excellent in terms of storage stability of appearance properties.
本発明の芳香液は、液状のまま液状芳香剤の形態で使用してもよく、また吸水性ゲルに含浸させてゲル状芳香剤の形態で使用してもよい。 The fragrance liquid of the present invention may be used in the form of a liquid fragrance as it is in the liquid state, or it may be impregnated in a water-absorbing gel and used in the form of a gel fragrance.
本発明の芳香液を液状芳香剤の形態で使用する場合、該芳香液をそのまま容器に収容して使用してもよく、また、紙、パルプ、合成繊維、合成樹脂、セルロース等の天然系樹脂等の基材に該芳香液を含浸させた状態で容器に収容して使用してもよい。 When the fragrance liquid of the present invention is used in the form of a liquid fragrance, the fragrance liquid may be used as it is in a container, or a natural resin such as paper, pulp, synthetic fiber, synthetic resin, or cellulose. Alternatively, the aromatic liquid may be impregnated in a container and used in a container.
本発明の芳香液を液状芳香剤の形態で使用した芳香器の好適な一実施形態として、容器に収納された芳香液を吸上げて外部に揮散させるための吸上揮散部材を備えている容器に、本発明の芳香液が収容されている芳香器が挙げられる。ここで、上記吸上揮散部材としては、少なくとも一部が容器内の芳香液に浸漬され、更に少なくとも一部が容器外部に露出可能に又は露出して設けられるような構成を備えていればよい。また、上記吸上揮散部材は、芳香液の吸上・揮散効果に優れた繊維層で主に全体が構成されていることが望ましく、繊維層は、植物繊維やパルプ等の天然繊維、レーヨン、ポリエステル、PET(ポリエチレンテレフタレート)、PP(ポリプロピレン)等の合成繊維又はそれらの混合繊維などの繊維質材料で構成することができる。特に、繊維層としては、スパンボンド法、スパンレース法などによって製造される不織布が好適であるが、この他、織物、編物等であってもよい。また、上記吸上揮散部材は、編織物、発泡ウレタン等の合成樹脂製のスポンジ材料であってもよい。上記吸上揮散部材の厚さは特に限定されないが、芳香液を収容する容器の大きさ、取り扱い性、香料揮散効果等の観点から、約2〜約20mm程度が好ましい As a preferred embodiment of the fragrance device using the fragrance liquid of the present invention in the form of a liquid fragrance, a container provided with a suction and volatilization member for sucking the fragrance liquid stored in the container and volatilizing it to the outside A fragrance device in which the fragrance liquid of the present invention is housed is mentioned. Here, the wicking volatilization member may have a configuration in which at least a part is immersed in the aromatic liquid in the container and at least a part is exposed or exposed outside the container. . In addition, it is desirable that the wicking volatilization member is mainly composed entirely of a fiber layer excellent in the wicking and volatilization effect of the fragrance liquid, and the fiber layer is made of natural fibers such as vegetable fiber and pulp, rayon, It can be comprised with fibrous materials, such as synthetic fibers, such as polyester, PET (polyethylene terephthalate), PP (polypropylene), or those mixed fibers. In particular, the fiber layer is preferably a non-woven fabric produced by a spunbond method, a spunlace method, or the like, but may also be a woven fabric, a knitted fabric, or the like. Further, the wicking member may be a synthetic resin sponge material such as knitted fabric or urethane foam. The thickness of the wicking volatilization member is not particularly limited, but is preferably about 2 to about 20 mm from the viewpoint of the size of the container for storing the fragrance liquid, the handleability, the fragrance volatilization effect, and the like.
上記吸上揮散部材を備える容器に、従来の芳香液を収容して使用すると、使用期間の経過に伴って芳香液中の界面活性剤の濃度が上昇し、これが吸上揮散部材の目詰まりを起こし、その結果、使用後期における芳香液の減量速度の低下をきたして香料の揮散性が十分に発揮できなくなる傾向があった。これに対して、本発明の芳香液は、界面活性剤の配合量が従来の芳香液に比して低減されており、使用後期に残存する界面活性剤の上記悪影響が回避されていることが1つの利点として挙げられる。即ち、本発明の芳香液によれば、上記吸上揮散部材を備える容器に収容して使用しても、使用後期においても芳香液の減量速度を安定に保つことができ、使用前期から後期に亘って均質な香気を放つことが可能になっている。 When a conventional fragrance liquid is contained and used in a container having the wicking volatilization member, the concentration of the surfactant in the fragrance liquid increases with the passage of the use period, which clogs the wicking volatilization member. As a result, there was a tendency that the fragrance volatility could not be sufficiently exhibited due to a decrease in the rate of weight loss of the aromatic liquid in the later stage of use. On the other hand, in the fragrance of the present invention, the blending amount of the surfactant is reduced as compared with the conventional fragrance, and the adverse effect of the surfactant remaining in the later stage of use is avoided. One advantage. That is, according to the fragrance liquid of the present invention, even if it is housed in a container equipped with the above-described wicking member, the rate of weight loss of the fragrance liquid can be kept stable even in the later period of use, from the previous period of use to the latter period. It is possible to release a uniform fragrance over the entire area.
また、本発明の芳香液をゲル状芳香剤の形態にする場合、アクリルアミド−アクリル酸塩共重合体等の公知の吸水性樹脂に、本発明の芳香液を含浸させることにより、該吸水性樹脂に本発明の芳香液を含有させればよい。従来の芳香液を使用したゲル状芳香剤では、使用後期において、濃度が上昇した界面活性剤によって香料の揮散性が妨げられる傾向があった。これに対して、本発明の芳香液を使用したゲル状芳香剤によれば、使用前期から後期に亘って安定に香料を揮散させることができ、従来の芳香液を使用したゲル状芳香剤の欠点が解消されている。 Further, when the fragrance liquid of the present invention is in the form of a gel fragrance, the water-absorbent resin is obtained by impregnating the fragrance liquid of the present invention into a known water-absorbent resin such as an acrylamide-acrylate copolymer. The aromatic liquid of the present invention may be contained in In a gel-type fragrance using a conventional fragrance, the volatility of the fragrance tends to be hindered by a surfactant having an increased concentration in the later stage of use. On the other hand, according to the gel-like fragrance using the fragrance of the present invention, the fragrance can be volatilized stably from the first period of use to the second stage, and the gel-like fragrance of the conventional fragrance is used. The drawbacks have been eliminated.
以下、実施例等を挙げて、本発明を説明するが、本発明はこれらの実施例に限定されるものではない。

芳香液の減量速度の測定結果を図2に示す。図2の縦軸の芳香液の残存割合(%)は、揮散開始時の芳香液の重量に対する、残存する芳香液の重量の割合である。揮散開始から揮散開始20日後までは、芳香液の減量速度は、実施例2及び比較例4は、略同一であったため、図2には揮散開始20日以降の芳香液の減量速度の測定結果を示す。更に、揮散開始32日後及び47日後に残存する芳香液を写真撮影した結果を図3に示す。この結果から、実施例2の芳香液では、揮散開始53日後まで減量速度が一定で安定であり、揮散開始53日後には、吸上揮散部材に浸透している芳香液以外には、芳香液の残存が殆ど認められなかった。これに対して、比較例4の芳香液では、揮散開始20日後から53日後に亘って徐々に芳香液の減量速度が減じており、揮散開始53日後でも、吸上揮散部材に浸透している芳香液以外にも、芳香液の残存が認められた。 The measurement result of the weight loss rate of the aromatic liquid is shown in FIG. The remaining ratio (%) of the aromatic liquid on the vertical axis in FIG. 2 is the ratio of the weight of the remaining aromatic liquid to the weight of the aromatic liquid at the start of volatilization. From the start of volatilization until 20 days after the start of volatilization, Example 2 and Comparative Example 4 were substantially the same in the rate of weight loss of the fragrance. Therefore, FIG. 2 shows the measurement results of the rate of weight loss of the fragrance after 20 days from the start of volatilization. Indicates. Furthermore, the result of having photographed the aromatic liquid which remain | survives 32 days after a volatilization start and 47 days after is shown in FIG. From this result, in the fragrance liquid of Example 2, the weight reduction rate is constant and stable until 53 days after the start of volatilization, and after 53 days from the start of volatilization, the fragrance liquid other than the fragrance liquid that has permeated the wicking volatilization member. There was hardly any remaining. In contrast, in the fragrance liquid of Comparative Example 4, the fragrance reduction rate gradually decreased from 53 days after the start of volatilization to 53 days, and even after 53 days from the start of volatilization, it penetrated into the wicking volatilization member. In addition to the fragrance, the fragrance remained.
更に、実施例2の芳香液の官能評価の結果を表2に示す。表2から明らかなように、実施例2の芳香液では、揮散開始44日後及び57日後では、嗅知される香気に差は認められなかった。これに対して、比較例4の芳香液では、揮散開始44日後及び57日後では、嗅知される香気に差が認められた。 Furthermore, Table 2 shows the results of sensory evaluation of the aromatic liquid of Example 2. As is clear from Table 2, in the fragrance liquid of Example 2, no difference was found in the scented smell after 44 days and 57 days after the start of volatilization. On the other hand, in the aromatic liquid of Comparative Example 4, a difference was recognized in the scented smell after 44 days and 57 days after the start of volatilization.
これらの結果から、実施例2の芳香液では、使用開始時から使用後期に亘って、芳香液の減量速度が安定であり、嗅知される香気も一定であることが明らかとなった。これに対して、実施例2に比べて界面活性剤の配合割合が高い比較例4の芳香液では、使用後期において芳香液の減量速度が徐々に減じてしまい、使用後期において、嗅知される香気も一定に維持できないことが確認された。 From these results, it was clarified that, in the fragrance liquid of Example 2, the weight loss rate of the fragrance liquid is stable and the scented smell is constant from the start of use to the later stage of use. On the other hand, in the fragrance liquid of Comparative Example 4 in which the blending ratio of the surfactant is higher than that in Example 2, the rate of weight loss of the fragrance liquid is gradually decreased in the latter period of use, and it is smelled in the later period of use. It was confirmed that the aroma could not be kept constant.
以上の結果から、界面活性剤の濃度を高めることによって透明な芳香液が得られるが、高濃度の界面活性剤は却って、使用後期において芳香液の減量速度を減じさせ、ひいては使用後期の芳香液の芳香効果を悪化させることが明らかとなった。 From the above results, a transparent fragrance can be obtained by increasing the concentration of the surfactant. However, a high concentration of the surfactant can reduce the rate of weight loss of the fragrance in the later stage of use, and consequently the fragrance liquid in the later stage of use. It became clear that the fragrance effect was worsened.
