BACKGROUND OF THE INVENTION
The present invention relates to a functional material using a volatile agent such as a fragrance, a deodorant, an antibacterial agent, an antifungal agent, and an insect repellent, and particularly to a functional material capable of visually confirming the end point of the effect. .
[0002]
[Prior art]
Conventionally, volatilizing dyes such as fragrances are mixed with volatile dyes, and together with the volatile chemicals, the dyes are volatilized at the same time. There is something that was made.
[0003]
[Problems to be solved by the invention]
However, since the volatilization agent volatilization and the dye volatilization do not necessarily coincide with each other in time, the medicinal effect ends when the volatilization agent remains but the dye volatilizes first. It is necessary to judge that the drug has been wasted, or on the contrary, all the volatile chemicals have been volatilized, but if the dye remains, it will be used as it is without medicinal properties There was a problem.
[0004]
On the other hand, with the volatilization of volatilizing chemicals, there is one that attempts to visually confirm the medicinal effect by color change caused by a chemical change of the colored organic compound itself. In this case, there is no time difference between the end point of the effect and the discoloration as described above, but the combination of the volatile drug and the colorable organic compound is important, and there is a disadvantage that the volatile drug that can be used is limited. . In addition, even those that can be used have the color of the color-forming organic compound due to the volatilization of the drug, so there is a disadvantage that it is not linked to the image of the end of the medicinal effect.
[0005]
Therefore, the present invention relates directly to the volatilization of the volatilizing agent and the change in color tone, thereby making it possible to reliably confirm the end time of the medicinal effect by visual observation and to provide a volatilizing agent capable of dissolving the oil-soluble dye. It is an object of the present invention to provide a functional material that can be used without exception and that can visually confirm the decrease of the drug by color reduction.
[0006]
[Means for Solving the Problems]
The present invention carries a volatilizing agent in which an oil-soluble dye and a surfactant are dissolved on a non-staining, that is, unfamiliar carrier with an oil-soluble dye, such as a hydrophilic material such as cellulose beads or wax. At least it is a functional material.
[0007]
The oil-soluble dye supported on the carrier is dissolved in the chemical solution when a volatile chemical is present. For this reason, since the carrier surface is covered with the chemical solution in which the dye is dissolved, the carrier exhibits a color (conceptual diagram of FIG. 1).
[0008]
When the volatilizing agent is volatilized and the concentration of the oil-soluble dye in the agent becomes high, the surfactant functions as an aggregating agent, and the oil-soluble dye is locally applied on the surface of the carrier that is not familiar to the oil-soluble substance. Thus, it aggregates and precipitates to form a large mass. As a result, the agglomerated and precipitated dye mass is only partially exposed from the surface of the carrier, so the color of the dye is not conspicuous, and the color of the carrier itself is exhibited as a whole (conceptual diagram of FIG. 2). reference).
[0009]
Therefore, it becomes possible to confirm the volatilization state of the volatile drug, that is, the presence or absence of the medicinal effect, by this change in color tone.
[0010]
In FIGS. 1 and 2, reference numeral 1 denotes a carrier, and 2 denotes a dye.
[0011]
The volatile chemicals used in this invention are lipophilic to dissolve the oil-soluble dyes described later, and as limonene, linalool, citral, carvone, methyl anthranilate, antibacterial and antifungal agents used as fragrances Allyl isothiocyanate, octyl aldehyde, eugenol, bromcinnamyl aldehyde, Hiba oil, cypress oil, eucalyptus oil used as essential oil and deodorant, pyrethroid, mint oil used as insect repellent, other repellents, There are pheromones.
[0012]
Examples of oil-soluble dyes include disperse dyes such as C.I. I. Disp. Yellow 64, C.I. I. Disp. Yellow 54, C.I. I. Disp. Red 60, C.I. I. Disp. Blue 60, C.I. I. Disp. Blue 56, C.I. I. Disp. Blue 334, oil-soluble dyes such as C.I. I. Solvent Yellow 33, C.I. I. Solvent Red 52, C.I. I. Solvent Blue 11, vat dyes such as C.I. I. Vat Yellow 1, C.I. I. Vat Red1, C.I. I. Vat Blue 1, sulfur dyes such as C.I. I. Sulphur Yellow 1, C.I. I. Sulphur Red3, C.I. I. SulphurBlue 1, a mordant dye such as C.I. I. Mordant Yellow 3, C.I. I. Mordant Red11, C.I. I. Mordant Blue 1, an azoic dye such as C.I. I. Azoic Yellow 2, C.I. I. Azoic Red2, C.I. I. Azoic Blue 6, etc.
[0013]
Surfactants include anionic surfactants such as sulfonates, sulfate esters, cationic surfactants such as aliphatic quaternary ammonium salts, benzalkonium salts, amphoteric surfactants such as carboxy There are betaine type, nonionic surfactants such as polyethylene glycol alkylphenyl ether, and anionic surfactants are particularly good.
[0014]
When the surfactant is not used, even if the volatilizing agent is volatilized and the concentration of the oil-soluble dye in the agent is high, the oil-soluble dye is less likely to agglomerate and precipitate. The dye is deposited in the form of a film on the entire surface of the carrier without forming a lump, so that it is difficult to distinguish the color change. The amount of the surfactant used is preferably 10 to 300% by weight based on the oil-soluble dye. If the amount is less than 10% by weight, the effect of the surfactant may be difficult to obtain. If the amount exceeds 300% by weight, it may be misunderstood as a result of aggregation and precipitation before the chemical has completely volatilized, and the medicinal effect has ended. Because.
[0015]
Next, as a carrier for supporting a volatile drug in which an oil-soluble dye is dissolved together with a surfactant, non-staining, that is, unfamiliar to oil-soluble dyes, for example, cellulose beads, cellulose sponge, and Cellulose porous materials such as paper, woven fabrics, nonwoven fabrics, hydrophilic porous materials such as calcium silicate, alumina, silica gel, zeolite, etc., or mineral wax (ozokerite), petroleum Waxes such as wax (paraffin wax, microcrystalline wax) and natural wax (fatty acid, carnauba wax, rice wax) are used. This means that when a carrier that is familiar to oil-soluble dyes is used, even if the carrier itself is dyed with oil-soluble dyes and the volatile chemicals are volatilized, the dyes do not aggregate and the color changes. It is thought that it does not. In addition, when the waxes are melted and volatile chemicals, oil-soluble dyes, and surfactants are kneaded, and the kneaded liquid is embedded in the pores of the hydrophilic porous material, the medicinal effect is visually confirmed. Further, it is more preferable because it can have sustained release properties.
[0016]

Moreover, the color tone judged visually the color of the bead at the time of preparation and when AIT completely volatilized. After volatilization, when the beads were impregnated into 10 g of AIT, the white beads turned blue again.
