JP7809311B2 - Device for improving the penetration of liquid, cream, gel or emulsion substances - Google Patents

Description

The present invention relates to a device that improves the penetration of liquid, cream, gel, or emulsion substances, such as water, lotion, or emulsion, into the skin.

Traditionally, to prevent the skin from drying out and to keep it moisturized, lotion is applied to the skin, followed by emulsion or cream to keep the moisture in.
However, even if lotion is applied to dry skin with reduced moisture content, the lotion does not penetrate the skin well. Therefore, before applying the lotion to the skin, an introductory beauty serum, also known as a booster cosmetic, is applied to increase the penetration rate of the skin, making it easier for lotion, emulsion, etc. to penetrate the skin.
On the other hand, the inventors of the present application have already invented and proposed a spatial potential generating device that generates an electric field in a specified space and preserves freshness by placing food or the like in that electric field, as well as a freshness preservation device that utilizes this spatial potential generating device (see Patent Documents 1 and 2).

The device for improving the penetration power of a liquid, cream, gel or emulsion substance according to the present invention comprises a housing having a substance storage section that is electrically insulated from the external environment and that stores a liquid, cream, gel or emulsion substance, and a space potential generating means that is provided in the housing and that forms an electric field having a predetermined frequency in the internal space of the substance storage section.Therefore, it has the effect of being able to improve the penetration rate of the substance by applying a voltage to the substance stored in the substance storage section within the electric field having a predetermined frequency generated by the space potential generating means.
Furthermore, the device for improving the penetration power of liquid, cream, gel or emulsion substances according to the present invention forms an electric field having a predetermined frequency inside the substance storage section, so that it is possible to improve the penetration rate of products made of liquid, cream, gel or emulsion substances contained in various types of containers such as vinyl or glass, such as cosmetics such as lotion, lotion or cream, or treatments or hair growth agents, simply by storing them inside the substance storage section without opening the container, making it possible to store these products in a hygienic and protected state while improving their penetration rate.
By providing the housing with an openable and closable lid member that allows access to the substance storage section, the electric field within the substance storage section can be stabilized, making it possible to efficiently apply voltage to the stored substance.
The space potential generating means may comprise a transformer magnetically coupling a primary coil and a secondary coil, a feedback control circuit returning one terminal of the secondary coil to one terminal of the primary coil to adjust the voltage in the secondary coil, output control means provided at the other terminal of the secondary coil to apply low-frequency vibration to the output of the secondary coil, and emitting means made of a conductive material provided at the other terminal of the secondary coil via the output control means, and may be configured to generate an electric field having a predetermined frequency in the space surrounding the emitting means by generating a leakage current having a voltage of a predetermined frequency and a weak current from the emitting means, and by placing the emitting means on the bottom wall or side wall of the substance storage section in the housing, an electric field having a voltage of a predetermined frequency and a weak current can be efficiently formed within the substance storage section by the output from the emitting means.

By storing the liquid, cream, gel, or emulsion cosmetic in the substance storage section and using the penetration improving device of the present invention as a cosmetic storage box, it is possible to improve the penetration rate of the cosmetic while it is stored, and the cosmetic with improved penetration rate can be used when in use.

1 shows a schematic side view of one embodiment of a device for improving the penetration of a liquid, cream, gel or emulsion substance according to the present invention. 2 is a schematic diagram showing the configuration of a space potential generating device provided in the penetration force improving device of FIG. 1. 1 shows a schematic side view of another embodiment of the device for improving the penetration of a liquid, cream, gel or emulsion substance according to the present invention.

Below, we will explain an embodiment of the penetration power improving device for liquid, cream, gel, or emulsion substances (hereinafter referred to as the penetration power improving device) of the present invention, with reference to one example shown in the attached drawings.
FIG. 1 is a schematic perspective view of an apparatus for improving the penetration power of a liquid, cream, gel, or emulsion substance according to the present invention.
In the figure, the symbol 20 indicates a housing, which is formed from a material that electrically insulates its interior from the external environment, such as ABS resin, and has a substance storage section 21 inside and an openable and closable lid member 22 on the top.
The space potential generating device 1 is provided below the substance containing section 21 in the housing 20 configured as described above.
As shown in FIG. 2, the space potential generating device 1 includes a transformer 4 in which a primary coil 2 and a secondary coil 3 are magnetically coupled.
One terminal 3a of the secondary coil 3 is connected to one terminal 2a of the primary coil 2 via a feedback control circuit 5 for adjusting the voltage in the secondary coil 3, and the other terminal (i.e., output terminal) 3b of the secondary coil 3 is connected to a first emitting means 8 and a second emitting means 9 via an output control means 6.
In FIG. 1, reference numeral 7 denotes an AC input outlet.
The first and second emitting means 8 and 9 are made of a conductive material.
In the space potential generating device 1 configured as described above, the current generated on the secondary coil 3 side by the feedback control circuit 5 is fed back to the primary coil 2, so that a high voltage can be obtained on the secondary coil 3 side with a small number of turns.
The feedback control circuit 5 and the output control means 6 are configured to generate a delay in the circuit and to apply a low frequency vibration of 20 to 100 Hz (50 Hz in this embodiment) to the output of the secondary coil 3 .
According to the space potential generating device 1 configured as described above, a weak current of a predetermined voltage is generated at the output of the secondary coil 3 by the action of the transformer 5, feedback control circuit 5, and output control means 6, and low-frequency vibration is applied to the output of the secondary coil 3. This, coupled with the fact that the output is only a single wire at terminal 3b and is not provided with a ground electrode, causes a leakage current having a voltage and weak current of a predetermined frequency to be generated around the first emitting means 8 and the second emitting means 9, and an electric field having a voltage and weak current of a predetermined frequency (for example, a voltage value of 10 to 1000 V and a current value of 0.2 A to 0.002 A) is formed around the first emitting means 8 and the second emitting means 9. Because this electric field has a constant frequency, charges propagate and spread through space, forming an electric field having a voltage and weak current of a predetermined frequency over a wide area.
The first emitting means 8 is formed of a plate-shaped conductive material and is provided on the bottom plate of the substance storage section 21. As a result, by operating the space potential generating device 1, the inside of the substance storage section 21 can be filled with an electric field having a voltage of a predetermined frequency and a weak current. The first emitting means 8 may be mesh-shaped, or may have openings formed therein.
The second emission means 9 is made of a resin, for example, a silicone resin, face mask and is provided with an output material inside. By activating the spatial potential generator 1, an electric field having a voltage of a predetermined frequency and a weak current (for example, a voltage value of 10 to 1000 V and a current value of 0.2 A to 0.002 A) is generated around the face mask. The spatial potential generator 1 emits a leakage current having a voltage of a predetermined frequency and a weak current from the emission means, making it possible to generate an electric field having a voltage of a predetermined frequency and a weak current around the face mask even through silicone resin. The second emission means 9 is detachably attached to the spatial potential generator 1 by a connection wire 9a, and is configured to generate an electric field when the connection wire 9a is connected to the spatial potential generator 1.
Although not limited thereto, in this embodiment, the outer diameter dimensions of the housing 20 are width 215 mm, depth 165 mm, and height 235 mm, the inner diameter dimensions of the substance storage section 21 are width 200 mm, depth 150 mm, and height 215 mm, and the voltage value of the electric field formed inside the substance storage section 21 by the spatial potential generating device 1 is 300 V, the current value is 0.002 A, and the frequency is 50 Hz.
The thickness of the silicone resin face mask covering the second emission means 9 is determined so that the second emission means 9 forms an electric field with a voltage of 200 V, a current of 0.002 A, and a frequency of 50 Hz within a range of 30 cm around it. Specifically, in this embodiment, the thickness of the silicone resin constituting the face mask is 2 mm. Note that the material of the face mask is not limited to silicone resin and can be changed to any material, such as cloth or leather.

When a liquid, cream, gel, or emulsion substance is contained in the substance storage section 21 of the penetration force improving device configured as described above, the space potential generating device 1 is operated to generate an electric field within the substance storage section 21, thereby causing a change in the state of the molecules that make up the liquid, cream, gel, or emulsion substance contained in the substance storage section 21, and improving the penetration rate of the substance into the skin, etc. Specifically, for example, when the space potential generating device 1 is operated with cosmetics such as lotion, milky lotion, or cream contained in the substance storage section 21, a change is caused in the molecular state of the cosmetics, thereby increasing their penetration rate into the skin. Also, for example, when the space potential generating device 1 is operated with a hair growth agent contained in the substance storage section 21, the penetration rate of the hair growth agent into the scalp can be improved. Furthermore, for example, when the space potential generating device 1 is operated with a treatment contained in the substance storage section 21, a change is caused in the molecular state of the treatment, thereby increasing their penetration rate into the hair.
Furthermore, with the face mask-shaped second releasing means 9, by wearing the face mask-shaped second releasing means 9 against the face with a cosmetic pack attached to the face or with lotion or the like applied to the face, it becomes possible to expose the face to an electric field having a voltage of a predetermined frequency and a weak current, which causes changes in the molecular state of the substances impregnated in the cosmetic pack, the lotion, etc., and improves the penetration rate of these substances into the skin.
The face mask-shaped second emission means 9 is configured to be detachable from the spatial potential generating device 1, and by connecting it to the spatial potential generating device 1 via a connecting wire, an electric field having a voltage of a predetermined frequency is formed around it.

Using the penetration power improvement device configured as described above, penetration tests were conducted on liquid, cream, gel, and emulsion substances. In the following penetration tests, the spatial potential generating device 1 was adjusted so that an electric field with a voltage of 300 V, a current of 0.002 A, and a frequency of 50 Hz was formed within the substance storage section 12 by the output of its first emission means 8, and a voltage of 300 V with a frequency of 50 Hz was applied to the substance placed inside.

Two bottles of "ELIXIR" lotion manufactured by Shiseido Co., Ltd. were prepared as liquid substance samples. One of them, sample 1, was placed in the substance storage section 21 of the penetration improving device and held in an electric field generated by operating the space potential generating device 1 at room temperature for 6 hours, after which the test was carried out three days later. The other sample, sample 2, was stored at room temperature without any treatment and was used for the test. The test was carried out in an environment of room temperature 25°C and humidity 49%.
Samples 1 and 2 were applied to three locations on the inner upper arms of seven subjects and left for 10 minutes. The applied samples were then wiped off, and after another five minutes, the penetration rates of the samples at the measurement sites from 0 to 18 micrometers deep were measured using an "in vivo confocal Raman spectroscopy system Model 3510" manufactured by River Diagnostics in the Netherlands. The results are shown in Table 1. Example 1 is the average test result for Sample 1 held in an electric field, and Comparative Example 1 is the average test result for Sample 2, which had not been treated. The values shown in the table are the Raman light intensity (unitless) at the measurement sites, and this Raman light intensity is proportional to the amount of components in the sample.
The test results confirmed that the amount of skin penetration of sample 1, which was treated using the penetration power improving device of the present invention, was greater than the amount of skin penetration of sample 2, which was not treated at all.

Two samples of the cream-like substance, "Nivea Cream" manufactured by Kao Corporation, were prepared. One of them, sample 3, was placed in the substance storage section 21 of the penetration improving device and held in an electric field generated by operating the space potential generating device 1 at room temperature for 24 hours, after which the test was carried out three days later. The other sample, sample 4, was stored at room temperature without any treatment and was used for the test. The test was carried out in an environment of room temperature 25°C and humidity 49%.
Samples 3 and 4 were applied to three locations on the inner upper arms of seven subjects and left for 10 minutes. The applied samples were then wiped off, and after another 5 minutes, the penetration rate of the samples was measured at a depth of 0 to 18 microns using an in vivo confocal Raman spectrometer Model 3510 manufactured by River Diagnostics in the Netherlands. The results are shown in Table 2. Example 2 is the average test result for Sample 3 held in an electric field, and Comparative Example 2 is the average test result for Sample 4, which had not been treated. The values shown in the table are the Raman light intensity (unitless) at the measurement site, and this Raman light intensity is proportional to the amount of components in the sample.
The test results confirmed that the amount of penetration into the skin of sample 3, which was treated using the penetration power improving device of the present invention, was greater than the amount of penetration into the skin of sample 4, which was not treated at all.

Two bottles of "Free Plus" emulsion from Kanebo Cosmetics Inc. were prepared as samples of the emulsion-like substance. One of them, sample 5, was placed in the substance storage section 21 of the penetration improving device and held in the electric field generated by operating the space potential generating device 1 at room temperature for 6 hours, after which the test was carried out three days later. The other sample, sample 6, was stored at room temperature without any treatment and was used for the test. The test was carried out in an environment of room temperature 25°C and humidity 49%.
Samples 5 and 6 were applied to three locations on the inside of the upper arm of one subject, left for 10 minutes, then wiped off. Five minutes later, the penetration rate of the sample was measured at a depth of 0 to 18 microns using an in vivo confocal Raman spectrometer Model 3510 manufactured by River Diagnostics, Netherlands. The results are shown in Table 3. Example 3 is the average test result for Sample 5 held in an electric field, and Comparative Example 3 is the average test result for Sample 6, which had not been treated. The values shown in the table are the Raman light intensity (unitless) at the measurement site, and this Raman light intensity is proportional to the amount of components in the sample.
The test results confirmed that the amount of skin penetration of sample 5, which was treated using the penetration power improving device of the present invention, was greater than the amount of skin penetration of sample 6, which was not treated at all.

Furthermore, a substance penetration test was carried out using the constructed face mask-shaped second emission means 9 of the penetration power improving device. In the following penetration test, the space potential generating device 1 was adjusted so that an electric field with a space potential of 200 V was formed around the second emission means 9 by a leakage current having a voltage of a predetermined frequency and a weak current emitted from the second emission means 9, and a voltage of 200 V was applied to the pack placed inside the face mask-shaped second emission means 9 (i.e., between the face mask-shaped second emission means 9 and the face).
Two samples were prepared: Mandom Corporation's Barrier Repair Sheet Mask, "Purupuru Ultra Moisture Type""Pack (ingredients: water, hydrolyzed hyaluronic acid, etc.)." For one of the samples, Sample 7, the mask was attached to the face, and then the face mask-like second release means 9 was placed over it. The spatial potential generator 1 was operated for 10 minutes, after which the face mask-like second release means 9 and Sample 7 were removed from the face and the moisture and oil content of the facial surface were measured. For the other sample, Sample 8, the mask was attached to the face and left for 10 minutes, after which Sample 8 was removed from the face and the moisture and oil content of the facial surface were measured. The moisture and oil content were measured using a USB rechargeable skin checker, "Bilulu Skin Checker USB," manufactured by Beautiful Angel Co., Ltd. The test environment was a room temperature of 25°C and a humidity of 49%.
The results of the above test carried out on seven subjects are shown in Tables 4 and 5.
Table 4 shows the rate of increase in facial surface moisture content after the test relative to the amount of moisture on the facial surface before the test, with Example 4 in the table showing the test results for Sample 7 and Comparative Example 4 showing the test results for Sample 8. Table 5 shows the rate of increase in facial surface oil content after the test relative to the amount of oil on the facial surface before the test, with Example 4 in the table showing the test results for Sample 7 and Comparative Example 4 showing the test results for Sample 8.
The test results confirmed that the moisture content on the facial surface of the subject who used Sample 7, which was combined with the face mask-shaped second releasing means 9 of the penetration power improving device according to the present invention, was higher than the moisture content on the facial surface of the subject who used Sample 8, which had not been treated in any way, and that the oil content on the facial surface of the subject who used Sample 7 was lower than the oil content on the facial surface of the subject who used Sample 8. These results confirmed that the use of the penetration power improving device according to the present invention improves the penetration rate of the ingredients impregnated in the "pack" used into the skin.

As described above, by using the penetration improving device according to the present invention, the penetration of liquid, cream, gel or emulsion substances can be improved.
Furthermore, since the penetration power improving device of this embodiment is configured to form an electric field in the substance storage section 21 inside the housing 20 using the spatial potential generating device 1, when used as a cosmetics storage box, for example, the penetration power of cosmetics, etc. can be improved simply by storing cosmetics, etc. in the substance storage section 21, and cosmetics, etc. with improved penetration power can be used when in use.
Furthermore, as described above, according to the penetration improving device of the present invention, the improved penetration rate of the cosmetic or other substance is maintained for at least three days after applying a voltage to the cosmetic or other substance in the substance storage unit 21 for six or 24 hours, so that even if the cosmetic or other substance is stored in the substance storage unit 21 at home and then removed from the substance storage unit 21 when going out and used away from home, the cosmetic or other substance will maintain its improved penetration rate. Furthermore, according to tests conducted by the inventors, it has been confirmed that the improvement in the penetration rate of the cosmetic or other substance processed by the penetration improving device of the present invention is maintained for at least one week.
Furthermore, in the above-described embodiment, the penetration improving device according to the present invention is used to treat beauty products such as lotions, creams, emulsions, and face packs, but the substances that can be treated with the penetration improving device according to the present invention are not limited to these embodiments, and it goes without saying that it can also be used for treatments and hair growth agents, for example. When used in treatments, it is possible to improve the penetration rate into hair, and when used in hair growth agents, it is possible to improve the penetration rate into the scalp.
In this embodiment, the second release means 9 is configured to be used as a face mask, but the configuration of the second release means 9 is not limited to this embodiment. For example, the second release means 9 may be formed in the shape of a head cover so that it can be worn on the head, or may be formed in the shape of a hair iron. By forming the second release means 9 in the shape of a head cover, for example, by applying a hair growth agent or the like to the scalp and then wearing the head cover-shaped second release means on the head, the penetration rate of the hair growth agent or the like into the scalp can be increased. Also, by forming the second release means 9 in the shape of a hair iron, for example, by applying a treatment to the hair and then using the hair iron-shaped second release means 9, the penetration rate of the treatment agent into the hair can be increased. Note that while hair irons typically require two-pole output, the penetration rate promoting device of this embodiment can generate an electric field with one pole, thereby simplifying the structure and reducing costs when manufacturing the hair iron.
Furthermore, the second release means 9 may be prepared in three types of forms, namely, a face mask type, a head cover type, and a hair iron type, and configured to be attachable to the penetration power improving device of this embodiment.

Next, a second embodiment of the penetration force improving device according to the present invention will be described.
FIG. 3 is a schematic diagram showing the structure of a second embodiment of the penetration force improving device according to the present invention.
Components that are the same as or equivalent to those in the first embodiment shown in FIGS. 1 and 2 are given the same reference numerals and detailed descriptions thereof will be omitted.
This penetration force improving device, like the first embodiment, comprises a housing 20 for containing a substance and a space potential generating device 1 provided in the housing 20.
In the figure, reference numeral 23 denotes a control device that controls the operation of the spatial potential generating device 1, reference numeral 24 denotes a voltage detection sensor that detects the voltage within the substance storage section 21 of the housing 20, reference numeral 25 denotes a lid opening/closing detection sensor that detects the opening and closing of the lid member 22, reference numeral 26 denotes a timer, and reference numeral 27 denotes a frequency input means.
The outputs of the voltage detection sensor 24 and the timer 26 are input to the control device 23, and the control device 23 controls the operation of the spatial potential generating device 1 based on the signal from the voltage detection sensor 24 so that an electric field with a voltage of 10 to 1000 V and a frequency of 20 to 100 Hz can be stably formed within the substance storage section 21 for the time set by the timer 26.
Furthermore, the control device 23 can be configured to input a signal from the lid opening/closing detection sensor 25 and execute operational control of the spatial potential generating device 1 using the opening and closing of the lid member 22 as a trigger. This makes it possible, for example, for a user to open the lid member 22, remove and use cosmetics or the like from the contents, and then place the cosmetics or the like back into the substance storage section 21 and close the lid member 22, after which the spatial potential generating device 1 can be operated to apply a voltage to the contained cosmetics or other substances for a predetermined time, thereby enabling efficient application of voltage to the cosmetics or other substances. Furthermore, even if the user removes and uses the cosmetics or the like from the substance storage section 21 before sufficient voltage has been applied to them, the operation of the spatial potential generating device 1 can be started again after the cosmetics or the like are placed in the substance storage section 21 and the lid member 22 is closed, and an electric field can be formed and a voltage can be applied to the contained cosmetics or the like for the set time, so that cosmetics or other substances will not continue to be used without their penetration rate being sufficiently improved.
Furthermore, the control device 23 is configured to be able to change the frequency of the low-frequency vibration added to the output by the output control means 6 in the spatial potential generating device 1 based on an input signal from the frequency input means 27. This makes it possible to change the frequency of the electric field depending on the item being stored, and to form an electric field with an optimal frequency depending on the item.
According to tests conducted by the inventors, it was confirmed that storing a substance such as cosmetics in the substance storage section 21 filled with an electric field of 10 to 1000 V and 20 to 100 Hz for 4 hours or more effectively improves the penetration rate of the substance, and that storing the substance for 12 hours or more does not result in any further improvement in the penetration rate. It was also confirmed that if the substance is stored for 3 hours or less, the improvement in the penetration rate of the substance is half that of a 6-hour treatment, and no satisfactory improvement is achieved.
Therefore, although not limited thereto, for example, by setting the minimum time of the timer 26 to 4 hours, it is possible to obtain a satisfactory improvement effect in the penetration rate of substances such as cosmetics.
