Description

芳香剤組成物Air freshener composition
 本発明は、芳香剤組成物に関する。詳細には、本発明は、揮発性有機化合物に該当しない溶剤、及び香料を含有する芳香剤組成物に関する。 The present invention relates to a fragrance composition. In detail, this invention relates to the fragrance | flavor composition containing the solvent which does not correspond to a volatile organic compound, and a fragrance | flavor.
 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、芳香剤が広く使用されている。 ◎ Air fresheners are widely used in order to eliminate the discomfort caused by odors in indoor spaces and storage spaces and to create comfortable spaces.
 芳香剤は、主に香料と溶剤で構成された芳香剤組成物を揮発装置によって室内空間や収納空間に揮散させることによって効果を発揮し、その揮散の程度は用いる芳香剤組成物の原料の組み合わせや揮散装置によって制御できる。 The fragrance exerts its effect by volatilizing a fragrance composition mainly composed of a fragrance and a solvent into an indoor space or a storage space by a volatilizer, and the degree of volatilization is a combination of the raw materials of the fragrance composition to be used. It can be controlled by a volatilization device.
 揮散装置には様々な種類があり、例えば、籐等天然由来の木片を揮散部材として用いて自然蒸散させるリードディフューザー(特許文献1)や、吸液芯部分に発熱体を取り付けて加熱することによって組成物を蒸散させるプラグタイプ(特許文献2及び特許文献3)、吸液芯部分にファンを取り付け、強制的に揮散させるファンタイプなどがある。 There are various types of volatilization devices, such as a reed diffuser (Patent Document 1) that spontaneously evaporates using a piece of natural wood such as rattan as a volatilizing member, or by heating with a heating element attached to the liquid absorption core part. There are a plug type for evaporating the composition (Patent Document 2 and Patent Document 3), a fan type for forcibly evaporating by attaching a fan to the liquid absorption core portion.
 揮散装置によって、芳香剤組成物に用いる香料や溶剤の種類及び配合は異なるが、これらの芳香剤組成物に用いる溶剤として、これまで主にエタノールや3-メトキシ-3-メチル-1-ブタノール、ジプロピレングリコールモノメチルエーテル等が使用されてきた。しかし、最近、「VOC」に関する規制に伴い、芳香剤組成物中のこれら溶剤の含量が規制されるようになった。「VOC」とは、「Volatile Organic Compounds(揮発性有機化合物)」の略で、当業者には公知の用語である。「VOC」に関する規制(以下「VOC規制」と称する場合がある)としては、例えば米国カリフォルニア州における一般消費者製品規則(第2項)があり、販売又は製造時に指定限界を超えて「VOC」を含有する消費者製品の販売、供給、販売の申込み、又は製造を取り締まる。本規制における「VOC」とは、California Consumer Products RegulationのArticle 2,§94508(a)(155)によって定められており、エタノールや3-メトキシ-3-メチル-1-ブタノール、ジプロピレングリコールモノメチルエーテルはそれに該当する。 Depending on the volatilization device, the type and composition of the fragrance and solvent used in the fragrance composition are different, but as solvents used in these fragrance compositions, ethanol, 3-methoxy-3-methyl-1-butanol, Dipropylene glycol monomethyl ether and the like have been used. However, recently, with the regulation regarding “VOC”, the content of these solvents in the fragrance composition has been regulated. “VOC” is an abbreviation of “Volatile Organic Compounds” and is a term known to those skilled in the art. As regulations relating to “VOC” (hereinafter sometimes referred to as “VOC regulations”), for example, there is a general consumer product regulation in California, USA (paragraph 2). Control the sale, supply, application for sale, or manufacture of consumer products containing. “VOC” in this regulation is defined by Article 2, §94508 (a) (155) of California Consumer Products Regulation, and includes ethanol, 3-methoxy-3-methyl-1-butanol, dipropylene glycol monomethyl ether. Corresponds to it.
 したがって、芳香剤組成物中の溶剤として用いられる「VOC」(以下「溶剤として用いられる「VOC」」をVOC溶剤と称する)の含量を指定限界以下まで低減する必要がある。しかしながら、上記のVOC溶剤は、芳香剤組成物の揮散プロファイルを保持することや香料成分の芳香剤組成物中への溶解に寄与しており、その含量を単純に低減すると製品性能を損なう恐れがある。
 芳香剤組成物中のVOC溶剤の含量を低減させる手段として、前述の「VOC」の定義に該当しない物性を持ち、かつ芳香剤組成物を構成する溶剤として使用しても製品性能を充分に発揮しうる溶剤に置き換えることが考えられる。
Therefore, it is necessary to reduce the content of “VOC” used as a solvent in the fragrance composition (hereinafter, “VOC used as a solvent” is referred to as a VOC solvent) to a specified limit or less. However, the above VOC solvent contributes to maintaining the volatilization profile of the fragrance composition and dissolution of the fragrance component into the fragrance composition. If the content is simply reduced, the product performance may be impaired. is there.
As a means to reduce the content of VOC solvent in the fragrance composition, it has physical properties that do not fall under the definition of “VOC” described above, and even when used as a solvent constituting the fragrance composition, the product performance is fully demonstrated. It is conceivable to replace it with a possible solvent.
 「VOC」に該当しない有機化合物としては、例えば「LVP-VOC」を挙げることができる。「LVP-VOC」は(1)標準圧力での沸点が216℃以上、(2)20℃での蒸気圧が0.1mmHg以下、(3)炭素数が12より多い、のうち、少なくとも1つの条件を満たすものと定義されている。ここで、「LVP-VOC」とは、California Consumer Products RegulationのArticle 2,§94508(a)(98)によって定められており、「Low vapor pressure Volatile Organic Compounds(低蒸気圧揮発性有機化合物)」の略である。以下溶剤として用いられるLVP-VOCをLVP-VOC溶剤と称する。 Examples of organic compounds not corresponding to “VOC” include “LVP-VOC”. “LVP-VOC” has at least one of (1) boiling point at standard pressure of 216 ° C. or higher, (2) vapor pressure at 20 ° C. of 0.1 mmHg or lower, and (3) having more than 12 carbon atoms. It is defined as satisfying the condition. Here, “LVP-VOC” is defined by Article 2 of the California Consumer Products Regulation, Article 2, §94508 (a) (98). Is an abbreviation. Hereinafter, LVP-VOC used as a solvent is referred to as an LVP-VOC solvent.
 芳香剤組成物に用いられるLVP-VOC溶剤としては、高沸点の炭化水素溶剤やジプロピレングリコールモノメチルエーテルアセテート(DPMA)等が知られている。しかし、芳香剤組成物に所望する揮発速度や、組み合わせて用いる香料が様々であり、上記のLVP-VOC溶剤のみで揮発速度を制御したり、香料を芳香剤組成物に均一に溶解させたりすることが出来ない場合があり、さらに多種のLVP-VOC溶剤の上市が望まれている。 As the LVP-VOC solvent used in the fragrance composition, a hydrocarbon solvent having a high boiling point, dipropylene glycol monomethyl ether acetate (DPMA) and the like are known. However, the volatilization rate desired for the fragrance composition and the fragrances used in combination vary, and the volatilization rate is controlled only by the above LVP-VOC solvent, or the fragrance is uniformly dissolved in the fragrance composition. In addition, there are demands for the launch of various LVP-VOC solvents.

<揮発評価試験1:リードディフューザーでの揮発試験>
 上記で得られた各々の芳香剤組成物25gを容量100mlのサンプル瓶に入れ、籐製のリード(直径3mm、長さ25cm、中国製)を5本挿して室温(20~25℃)で静置し、芳香剤組成物質量の減少量を経時測定して、試験開始時からの質量減少率を求めた。質量減少率(%)と経時(日)の関係を図1に示す。
<Volatilization evaluation test 1: Volatilization test using a reed diffuser>
25 g of each fragrance composition obtained above is put into a sample bottle with a capacity of 100 ml, and five rattan leads (diameter 3 mm, length 25 cm, made in China) are inserted and statically kept at room temperature (20-25 ° C.). The amount of decrease in the amount of the fragrance composition material was measured over time, and the mass reduction rate from the start of the test was determined. The relationship between the mass reduction rate (%) and time (days) is shown in FIG.
 図1に示すように、IPD-DAはVOC溶剤であるMMBよりも揮発速度がやや遅いものの、既存のLVP-VOC溶剤であるDPMAよりも速い揮発速度であり、IPD-ACはDPMAよりもやや遅い揮発速度となった。したがって、IPD-AC及びIPD-DAを用いることで、所望の揮発速度に応じた芳香剤組成物が得られる。また、MMBの場合においては、質量減少率が90%を達したあたりから揮発速度が低下する傾向にあるが、IPD-ACやIPD-DAはその程度が緩やかであった。芳香剤組成物においては揮発速度が一定であるほうが好ましく、この点ではIPD-DAやIPD-ACはMMBよりも揮発速度が安定しており、優れていると言える。DPGやTECはLVP-VOCではあるが、揮発速度が遅すぎ、リードディフューザー向けの芳香剤組成物としては不適である。 As shown in FIG. 1, although IPD-DA has a slightly slower volatilization rate than MMB, which is a VOC solvent, it has a faster volatilization rate than DPMA, which is an existing LVP-VOC solvent, and IPD-AC is somewhat slower than DPMA. Slow volatilization rate. Therefore, by using IPD-AC and IPD-DA, a fragrance composition corresponding to a desired volatilization rate can be obtained. In the case of MMB, the volatilization rate tends to decrease after the mass reduction rate reaches 90%, but the degree of IPD-AC and IPD-DA is moderate. In the fragrance composition, it is preferable that the volatilization rate is constant. In this respect, it can be said that IPD-DA and IPD-AC are superior to MMB in that the volatilization rate is more stable. DPG and TEC are LVP-VOCs, but their volatilization rate is too slow and are not suitable as a fragrance composition for a reed diffuser.
 <揮発評価試験2:プラグタイプ揮散装置での揮発試験>
 前記実施例-1~2、比較例-1~2、参考例-1~2で得られた各々の芳香剤組成物25gを、プラグ式揮散装置(特許文献3参照)の容器に充填し、揮散装置本体に取り付け、次いで芳香剤組成物中にPET製吸液芯(サイズ:直径7mm×長さ75mm)を浸し、該吸液芯の芳香剤組成物に浸されていない上部の部分を揮散装置に配置した。揮散装置に取り付けられたプラグを電源に挿し込み、吸液芯上部を80℃に加熱することによって、吸液芯に浸透した芳香剤組成物を蒸散させた。芳香剤組成物の質量変化を経時測定することによって試験開始時からの質量減少率を求めた。質量減少率(%)と経時(日)の関係を図2に示す。
<Volatilization evaluation test 2: Volatilization test with plug-type volatilization device>
25 g of each of the fragrance compositions obtained in Examples 1 to 2 and Comparative Examples 1 to 2 and Reference Examples 1 to 2 was filled in a container of a plug-type volatilization apparatus (see Patent Document 3). Attach to the volatilization device body, then immerse the PET absorbent core (size: diameter 7mm x length 75mm) in the fragrance composition, and volatilize the upper part of the absorbent core that is not immersed in the fragrance composition Arranged in the apparatus. The plug attached to the volatilization device was inserted into a power source, and the upper part of the liquid absorbent core was heated to 80 ° C. to evaporate the fragrance composition penetrating the liquid absorbent core. The mass change rate from the start of the test was determined by measuring the mass change of the fragrance composition over time. The relationship between the mass reduction rate (%) and time (days) is shown in FIG.
 図2に示すように、IPD-AC及びIPD-DAは既存のLVP-VOC溶剤であるDPMAと同等、DPGよりも速い揮発速度であった。したがって、IPD-AC及びIPD-DAを用いることで、所望の揮発速度に応じた芳香剤組成物が得られる。TECはLVP-VOCではあるが、揮発速度が遅すぎ、プラグタイプ向けの芳香剤組成物には不適である。 As shown in FIG. 2, IPD-AC and IPD-DA were equivalent to DPMA, which is an existing LVP-VOC solvent, and had a faster volatilization rate than DPG. Therefore, by using IPD-AC and IPD-DA, a fragrance composition corresponding to a desired volatilization rate can be obtained. Although TEC is LVP-VOC, the volatilization rate is too slow and is not suitable for a fragrance composition for plug type.
 本発明により得られる芳香剤組成物は、溶剤としてIPD-AC及びIPD-DAの少なくとも一種を用いる。該溶剤はVOCに該当しないため、本発明の芳香剤組成物はVOCの規制を受けず、安全に使用することができる。また、本発明の芳香剤組成物は、揮散速度が安定しており、居室用、車内用、収納用、トイレ用等に適用できる。さらに、リードディフューザー、プラグタイプ、ファンタイプ等の揮発装置にも適用できる。 The fragrance composition obtained by the present invention uses at least one of IPD-AC and IPD-DA as a solvent. Since the solvent does not correspond to VOC, the fragrance composition of the present invention is not subject to VOC regulations and can be used safely. In addition, the fragrance composition of the present invention has a stable volatilization rate and can be applied to living rooms, in-cars, storage, toilets, and the like. Furthermore, the present invention can be applied to a volatile device such as a lead diffuser, a plug type, and a fan type.
