Description

  The present invention relates to a volatilization liquid that causes a volatilization member to absorb and volatilize. More specifically, the present invention is a volatilization liquid that causes a volatilization member to absorb and volatilize, the volatilization agent is solubilized, and further, a decrease in volatilization rate in the later stage of use can be suppressed, and the volatilization agent It relates to a volatilization liquid excellent in the sustainability of the effect. Furthermore, this invention relates to the volatilizer using the said volatilization liquid.

  Conventionally, volatilizing liquids containing volatile agents such as fragrances and pest repellents to impart fragrances to indoor and automobile spaces and to avoid flying pests such as mosquitoes, chironomids, moths and flies. Is widely used. Since volatile chemicals that can exert such aroma and pest repellent effects are usually oily, it is necessary to solubilize them in a volatile liquid.

  Conventionally, nonionic surfactants are mainly used for solubilization of volatile chemicals. Nonionic surfactants do not exhibit ionicity like anionic surfactants and cationic active surfactants, and therefore do not precipitate or discolor due to reaction with other additive components. It is considered to be most suitable for solubilization, and plays a central role in solubilization of volatile drugs (see, for example, Patent Document 1). Further, in the conventional technology, a relatively large amount of nonionic surfactant is required to solubilize the volatile drug, but the surfactant does not volatilize. There is a disadvantage that the nonionic surfactant added in a relatively large amount remains at the end. Such a defect may lead to deterioration of the appearance at the end of volatilization, which may cause discomfort to the user.

  On the other hand, anionic interfacial agents may be added to volatilization liquids, but they are used only as auxiliary agents for the purpose of raising the cloud point. It did not play a role of solubilization.

  Further, in order to volatilize the volatilization liquid efficiently, a volatilizer designed to volatilize in a state where it is impregnated in a volatilizing member made of a water-absorbing material such as a fiber material or a wood material is used. Although such a volatilizer can volatilize the volatilization liquid efficiently, there is a drawback that the volatilization rate of the volatilizing agent is reduced and the effect of the volatilizing agent is reduced in the middle and later stages of use. The cause of the decrease in the volatilization rate in the middle and late period of use has not been elucidated, and the prior art has not been able to take an effective means for suppressing the decrease in the volatilization rate of the volatile drug in the mid or late period of use. There is no current situation.

Japanese Patent No. 5594979

  The present inventor conducted an intensive study to investigate the cause of the decrease in the volatilization rate of the volatile drug in the middle and later stages of use in the conventional volatile liquid, and surprisingly, it was added to solubilize the volatile drug. It has been clarified that a large amount of nonionic surfactants are responsible for the volatilization rate of volatilizing agents in the middle and late stages of use. Specifically, in the conventional volatilization liquid, as the usage time elapses, a large amount of nonionic surfactant accumulates on the volatilization member and clogs the volatilization member. I found out that it contributed to the decrease in speed. However, in the prior art, a sufficient amount of a nonionic surfactant is indispensable for solubilization of a volatile drug, and a decrease in the amount of nonionic surfactant added is insolubilization of a volatile drug or a decrease in solubilization stability. Based on the knowledge of the prior art, a technique for avoiding a decrease in volatilization rate in the middle and later stages caused by accumulation of nonionic surfactant in the volatilization member is considered. I can't.

  Under such a background, the present invention is a volatilizing liquid that is absorbed into a volatilizing member and volatilized, the volatilizing agent is stably solubilized, and the volatilization rate of the volatilizing agent in the middle and later stages of use. It aims at providing the volatilization liquid which can suppress the fall of this and is excellent in the sustainability of an effect.

  The present inventor has intensively studied to solve the above problems, and surprisingly, by using an anionic surfactant as a main agent for solubilizing the volatile drug, the volatile drug is sufficiently obtained. It was found that it is possible to prepare a volatilization liquid that can be solubilized in the medium and that suppresses a decrease in the volatilization rate of the volatilizing drug in the middle and later stages of use and is excellent in sustainability of the effect. More specifically, in a volatilizing liquid containing a volatilizing agent, a surfactant, and water, the volatilizing member absorbs and volatilizes, and at least an anionic surfactant is used as the surfactant and volatilized. By setting the ratio of the anionic surfactant per 100 parts by weight of the total amount of surfactants contained in the liquid to 40 parts by weight or more, the volatilizing agent can be solubilized, and the volatilization rate in the middle and later stages is reduced. It was found that the sustainability of the effect of the volatile drug is improved. Further, the present inventors have also found that the volatilization liquid can solubilize the volatile drug even if the total content of the surfactant is reduced, and the amount of the surfactant remaining at the end of volatilization of the volatile drug can be reduced. The present invention has been completed by further studies based on these findings.

Test Example 1: Evaluation of the solubilization and volatilization sustainability of citronella fragrance A volatilization liquid (aromatic liquid) having the composition shown in Tables 1 and 2 was prepared. Specifically, first, an aqueous solution was prepared by adding a predetermined amount of components other than citronella flavor and surfactant to water and dissolving them. Next, a mixed liquid in which a predetermined amount of citronella fragrance and a surfactant are mixed is prepared, and the mixed liquid is gradually added to the aqueous solution while stirring, under the condition of 5 minutes (100 rotations / minute) after completion of the addition. A volatilization liquid was prepared by stirring.
In addition, all the processes of preparation of volatilization liquid were performed at room temperature.

The external appearance of each obtained volatilization liquid was confirmed visually, and the degree of solubilization of the citronella tone fragrance was evaluated according to the following criteria.
<Criteria for degree of solubilization>
A: Transparent.
○: Slightly cloudy.
Δ: Cloudy.
X: The fragrance | flavor has isolate | separated.

Moreover, in order to evaluate the sustainability of the fragrance of each obtained volatilization liquid, the following test was done. 275 ml of each volatilization liquid was accommodated in a volume of 365 ml (opening 12.6 cm ² , bottom area 46.3 cm ² , height 7 cm). Next, a volatile member for sucking up the volatile liquid in the container and evaporating it out of the container was inserted into the container in which the volatile liquid was put. The volatilization member used was obtained by folding the X region of the rayon nonwoven fabric (thickness 0.5 cm) in the shape (plan view) shown in A of FIG. 1 into the state shown in B of FIG. used. In addition, as for the used volatilization member, the area | region of X shown to B of FIG. 1 is exposed outside a container, and the area | region of Y shown to B of FIG. 1 is inserted in a container, and it is immersed in the volatilization liquid in a container. Installed.

  The thus prepared volatilizer in which the volatilization liquid was capable of being volatilized was left in the room to start volatilization of the volatilization liquid. Immediately after the start, when the volatilization liquid in the container was reduced by about 45 to 55% (mid-use period) and when the volatilization liquid in the container was reduced by about 75 to 85% (late use period), 6 panelists In accordance with the determination criteria, the scent strength, the preference and quality of the scent, and the overall evaluation of the scent (scent strength, preference and overall evaluation of the scent) were scored. In this study, 6 persons who passed the olfactory test of the Smell / Kaori Environment Association of the Public Interest Incorporated Association and had more than 2 years of experience in sensory evaluation of fragrance were selected as panelists. The average score determined by the panelists was calculated.

<Judgment criteria for fragrance strength>
Score: Content 0: Weak 2: Slightly weak 4: Just good 6: Slightly strong 8: Strong

<Judgment criteria for scent preference and quality>
Score: Content-2: Bad-1: Somewhat bad 0: Not good 1: Somewhat good.
2: Good

<Criteria for comprehensive evaluation of fragrance>
Score: Contents-2: Inappropriate-1: Somewhat inappropriate 0: Cannot be said 1: Somewhat appropriate 2: Suitable

  The results of evaluating the degree of solubilization of the fragrance are shown in Tables 1 and 2, and the results of evaluating the persistence of the fragrance are shown in FIG. From this result, when the anionic surfactant occupies 40 parts by weight or more per 100 parts by weight of the total amount of the surfactant contained in the volatilization liquid, the perfume can be solubilized, and in particular, the anionic surfactant When the amount of the agent was 50 parts by weight or more, particularly 50 to 90 parts by weight, the fragrance was sufficiently solubilized and had an appearance property with extremely high transparency. Further, in the volatilization liquid containing the anionic surfactant at the above ratio, the perfume was sufficiently solubilized even if the total amount of the surfactant was 160 parts by weight per 100 parts by weight of the perfume. Further, in the volatilization liquid containing the anionic surfactant at the above ratio, the fragrance strength, scent preference and quality, and the scent overall evaluation are almost constant immediately after the start of use, in the middle period, and in the latter stage. The volatility of the fragrance was sustained even in the middle and late stages.

On the other hand, in the volatilization liquid (conventional volatilization liquid) containing 70 parts by weight or more of the nonionic surfactant per 100 parts by weight of the total amount of the surfactant, the total amount of the surfactant is 240 parts by weight per 100 parts by weight of the fragrance. In this case, the fragrance could be solubilized, but when the total amount of the surfactant was reduced to 160 parts by weight per 100 parts by weight of the fragrance, the fragrance could not be sufficiently solubilized. Furthermore, in the volatilization liquid containing the nonionic surfactant at such a ratio, the fragrance strength, the preference and quality of the fragrance, and the overall evaluation of the fragrance are lowered in the middle and later stages, and the fragrance is volatilized. Sex decreased with time.

Test Example 2: Evaluation of solubilization and volatilization sustainability of chamomile fragrance A volatilization liquid (aromatic liquid) having the composition shown in Table 3 was prepared, and the degree of solubilization of the fragrance and volatilization sustainability were evaluated. The preparation of the volatilization liquid, the evaluation of the solubilizing degree of the fragrance, and the evaluation of the volatility persistence in this Test Example 2 were performed in the same manner as in Example 1.

The results of evaluating the degree of solubilization of the fragrance are shown in Table 3, and the results of evaluating the persistence of the fragrance are shown in FIG. From this result, even when chamomile flavor is used, if the anionic surfactant occupies 40 parts by weight or more per 100 parts by weight of the total amount of surfactant contained in the volatilization liquid, the flavor is solubilized. It was confirmed that it was possible. Furthermore, from this test result, even if the volatilization liquid containing the anionic surfactant at the above ratio is 100 parts by weight of the fragrance, the amount of the surfactant is 160 parts by weight. It was confirmed that the volatility of the fragrance can be maintained even in the latter and middle stages of use.
