Description

The present invention relates to a fragrance composition for a piezojet type fragrance device.

Conventionally, an air freshener solution obtained by diluting a fragrance with ethanol, water, etc. is discharged into a space in the form of fine droplets (aerosol) of several hundred microns or less using the vibration pressure of an electromechanical conversion element (piezoelectric element, etc.). , Piezo type aroma release device is known. The piezo-type fragrance device has the feature that it can quickly present a small amount of fragrance that is not too strong even if a person directly smells it and can enjoy the scent gently. In recent years, it has been used as an indoor fragrance device. It is widespread.

As a technique for releasing a fragrance into a space in the form of fine droplets (aerosol), a fragrance composition having a specific viscosity, ClogP, and surface tension optimal for forming fine droplets (Patent Document 1). ), In the method of converting the fragrance component into fine droplets on the vibrating plate, the fragrance component having a steam pressure exceeding 0.008 mmHg is the main component, and the fragrance component having the lowest steam pressure is less than 2% of the entire fragrance composition. , A method of minimizing the perfume component remaining on the vibrating plate without volatilization (Patent Document 2), in a system for atomizing the perfume using a heater or an element containing a piezoelectric crystal, the microfluidic delivery member is clogged. A method of blending a fluid composition in which the amount of suspended solids is limited or absent (Patent Document 3), a fragrance droplet generator by a piezojet method and a small motor fan are combined to create an air flow by the fan. A method using a fragrance composition in which the average value of the boiling point depending on the weight molar concentration is less than 200 ° C. in an fragrance directed upward from the horizontal (Patent Document 4), and in a dispenser using a piezoelectric element or the like, water and volatile water-soluble A method of stably dissolving a fragrance in a solvent containing a sex organic compound (Patent Document 5) is known.

International Publication No. 2013/163368 Pamphlet Special Table 2005-517520 Special Table 2018-538072 Gazette International Publication No. 2018/19 1043 Pamphlet Special Table 2018-52 2014 Issue

However, in each of the techniques described in Patent Documents 1 to 5, the composition of the fragrance component is adjusted to the viscosity of the fragrance, the water-octanol partition coefficient (ClogP), so that the fragrance composition can easily form a good mist state. It is limited by using specific physical property values such as surface tension and boiling point, and the technique described in Patent Document 5 improves the stability of the solution by using water and a specific water-soluble organic compound as a solvent. It stays in the technology.

Further, in general, the fragrance solution contains a plurality of fragrance components, and depending on the concentration of the fragrance and the composition of the fragrance components, the piezo type fragrance may not form fine droplets and may not be ejected. In addition, as the number of sprays increases, solvents such as ethanol and fragrance components that easily volatilize volatilize faster from the discharge port, so that the composition of the solution may change and the discharge state and fragrance tone may not be stable.

On the other hand, in the piezojet type fragrance device, since a control plate having pores (orifice) is provided at the tip of the discharge port, the fragrance composition is difficult to use on the orifice control plate depending on the concentration of the fragrance and the composition of the fragrance component. If the orifice is blocked by remaining as a soluble viscous substance or solid substance and the orifice is not blocked, the easily volatile components in the fragrance composition volatilize from the outlet. As a result, the composition of the fragrance composition changes, and in a device whose discharge port is below the liquid level of the fragrance composition of the fragrance device, there is a problem that the fragrance composition drips from the discharge port. The inventors have found.

Therefore, the present invention relates to a fragrance composition that can be stably and repeatedly discharged from a piezojet type fragrance device, and can also suppress composition changes due to volatilization from the discharge port and dripping from the discharge port.

Therefore, as a result of diligent studies, the inventors used a fragrance compound whose physical property values satisfy certain conditions for the fragrance composition used in the piezojet type fragrance device, and used ethanol and water as solvents, and their contents. It was found that the above-mentioned problem can be solved by setting the above within a specific range. That is, by preparing the fragrance composition as described above, after spraying, some components in the fragrance composition become easily soluble precipitates on the orifice control plate, blocking the orifice and from the discharge port. It is possible to suppress the composition change of the fragrance composition due to the volatilization of the easily volatilizing component of the fragrance composition, and it is also possible to suppress the dripping of the fragrance composition from the discharge port, while the precipitate is sprayed next. It was found that the fragrance composition ejected in the above can be easily redissolved and re-sprayed.

That is, the present invention is a fragrance composition containing the following components (A), (C) and (D), wherein the content of the component (A) is 0.1% by mass or more and 12% by mass or less, and the component (C). The present invention provides a piezojet type fragrance composition for an fragrance device, wherein the content of the following component (B) is 45% by mass or more and 99% by mass or less, and the content of the following component (B) is 3% by mass or less.
