Japanese Unexamined Patent Publication No. 62-33115

However, the spray composition for application to the human body described in Patent Document 1 does not provide a sufficient cooling sensation. Additionally, pentane is flammable and poses a fire hazard. Furthermore, the spray composition for application to the human body described in Patent Document 1 does not provide a long-lasting cold sensation.

<Spray composition>
A spray composition according to an embodiment of the present invention consists of a stock solution containing a hydrofluoroolefin with a boiling point of 5 to 40°C and an alcohol, and a compressed gas. The compressed gas includes at least one of carbon dioxide gas and nitrous oxide. The spray composition of the present embodiment is safe against fire, and when sprayed onto the application site, such as the scalp or arm, can impart an excellent cooling sensation to the application site. In addition, the cold sensation tends to last. Each will be explained below.

(undiluted solution)
The stock solution contains a hydrofluoroolefin with a boiling point of 5 to 40°C and an alcohol. Moreover, it is preferable that the stock solution contains water.

- Hydrofluoroolefins with a boiling point of 5 to 40°C Hydrofluoroolefins with a boiling point of 5 to 40°C are blended to increase safety against fire. Furthermore, hydrofluoroolefins with a boiling point of 5 to 40°C are blended as a solvent that dissolves a large amount of compressed gas in order to impart a moderate cooling sensation to areas to which it is applied, such as the scalp and arms. Furthermore, a hydrofluoroolefin having a boiling point of 5 to 40°C is blended to adjust the drying properties of the spray composition.

Hydrofluoroolefins with a boiling point of 5 to 40°C are, for example, trans-1-chloro-3,3,3-trifluoropropene (HFO-1233zd(E), boiling point 19°C), cis-1-chloro-3,3 , 3-trifluoropropene (HFO-1233zd(Z), boiling point 39°C) and the like are preferred. The hydrofluoroolefins having a boiling point of 5 to 40°C in this embodiment are other hydrofluoroolefins such as trans-1,3,3,3-tetrafluoropropene (boiling point -19°C), 2,3,3,3 -It has a higher boiling point than tetrafluoropropene (boiling point -29°C), etc.). Therefore, when a spray composition is injected, the vaporization rate of hydrofluoroolefins with a boiling point of 5 to 40°C can be adjusted depending on the amount of dissolved compressed gas without instantaneous vaporization, and the vaporization rate can be adjusted for a long time at the application site. It can provide a moderate cooling sensation for a long time. Moreover, the spray composition easily dries appropriately at the application site.

(compressed gas)
The compressed gas is blended as a propellant to pressurize the stock solution and atomize it into a fine mist. In addition, the compressed gas is partially dissolved in the stock solution, and when the spray composition is discharged to the outside, the dissolved compressed gas becomes fine bubbles, which promotes the vaporization of the hydrofluoroolefin. Provides a moderate cooling sensation due to heat of vaporization. The compressed gas also adjusts the cooling temperature and the duration of the cooling sensation.

The compressed gas contains at least one of carbon dioxide gas and nitrous oxide. Compressed gas has a high solubility in hydrofluoroolefins, and can promote vaporization of hydrofluoroolefins during spraying, thereby imparting an excellent cooling sensation to the application area.

Further, in order to adjust the cooling sensation, a compressed gas having a low solubility in the hydrofluoroolefin, such as nitrogen, air, oxygen, or hydrogen, may be used in combination.

The compressed gas is preferably filled so that the pressure inside the container at 25° C. is 0.2 MPa or more, more preferably 0.3 MPa or more. Further, the compressed gas is preferably filled so that the pressure inside the container at 25° C. is 0.8 MPa or less, more preferably 0.7 MPa or less. By filling the compressed gas so that the pressure is within the above range, the compressed gas dissolves in the stock solution to a predetermined concentration, and when it is discharged, it promotes the vaporization of the hydrofluoroolefin, giving an excellent cooling sensation. and a lasting cooling sensation. Note that the amount of compressed gas dissolved at which the equilibrium pressure becomes 0.5 MPa at 25° C. is preferably 0.3 to 10.0 g in 100 mL of the stock solution.

Returning to the explanation of the spray composition as a whole, the method for preparing the spray composition is not particularly limited. For example, the composition for spraying can be prepared by filling the above-mentioned stock solution into a container body, attaching an aerosol valve to the container body and sealing it, filling the container with compressed gas from the aerosol valve, and dissolving the compressed gas in the stock solution to saturation. It can be manufactured by

When such a stock solution is sprayed with a compressed gas, the dissolved compressed gas accelerates the vaporization of the hydrofluoroolefin at the application site such as the scalp or arm, giving an excellent cooling sensation to the application site. be able to. In addition, the cold sensation tends to last.

<Injection products>
A spray product according to an embodiment of the present invention is filled with the above-described spray composition and discharges the stock solution under pressure with a compressed gas. Note that the injection product of this embodiment only needs to have a configuration that can pressurize and inject the stock solution with compressed gas, and such a configuration is not particularly limited. Therefore, in the present embodiment, as an example, a spray product will be described which mainly includes a container body filled with a spray composition and compressed gas, and a valve mechanism attached to the container body.

(container body)
The container body is a container filled with stock solution and compressed gas. The container body is a bottomed cylindrical pressure-resistant container having an opening at the top. The opening is a filling port for filling the stock solution, and is closed by a valve mechanism described later.

The material of the container body is not particularly limited. For example, the material of the container body is metal such as aluminum or tin, various synthetic resins, pressure-resistant glass, or the like.

(valve mechanism)
The valve mechanism is a member for closing and sealing the opening of the container body. Further, the valve mechanism mainly includes a housing, a stem in which a stem hole is formed that communicates the inside and outside of the container body, and a stem rubber that is attached around the stem hole and closes the stem hole. The housing accommodates the stem. The stem is a substantially cylindrical portion, and has a passage within the stem through which the spray composition taken into the housing during discharge passes. A stem hole is formed near the lower end of the stem passageway, which communicates the space within the housing with the stem passageway. A spray member for discharging the spray composition is attached to the upper end of the stem. The stem rubber is a member that is attached around the stem hole and is used to appropriately isolate the interior space of the housing from the outside. The stem rubber is a disc-shaped member, and when not ejecting, its inner circumferential surface is brought into close contact with the outer circumferential surface of the stem in which the stem hole is formed, thereby closing the stem hole.

(Injection member)
The spray member is a member for discharging the spray composition, and is attached to the upper end of the stem. The injection member mainly includes a nozzle section in which an injection hole is formed, and an operation section operated by a user with a finger or the like. A spray composition is discharged from the discharge hole. The number and shape of the discharge holes are not particularly limited. There may be a plurality of discharge holes. Further, the shape of the discharge hole may be approximately circular, approximately angular, or the like.

In the injection product of this embodiment, when the injection member is pushed down, the stem of the valve mechanism is pushed down. This causes the stem rubber to bend downward and the stem hole to open. As a result, the inside of the container body and the outside communicate with each other. When the inside of the container body and the outside communicate with each other, the liquid level of the stock solution is pressed by the pressure of the compressed gas mainly present in the gas phase portion of the container body. As a result, the stock solution is taken into the housing, passes through the stem hole and the passage within the stem, is sent to the injection member, and is then discharged from the discharge hole.
