As shown in fig. 1, the cosmetic dustproof performance test apparatus 10 of the present invention, which can not only completely protect the respiratory organs of a subject from artificial dust, but also maintain the density of artificial dust suspended in the air to be uniform around the arm a coated with a cosmetic, includes a chamber 100, an insertion unit 200, a dust injection unit 300, a cleaning unit 400, and a gas injection unit 500.
The chamber 100 is a structure forming an inner space 101 isolated from the outside, and includes a body 110 and a door 120. The body 110 forms the internal space 101 by weaving a transparent glass plate or a resin plate into a hexahedral shape. The door 120 is rotatably formed on one surface of the body 110. The door 120 isolates the internal space 101 from the outside when closed, and forms a passage connecting the internal space 101 and the outside when opened.
As shown in fig. 1 to 3, the insertion unit 200 is a structure forming an insertion passage 211 through which the arm a of the subject is inserted into the internal space 101, and includes a semicircular flange 210, a closing member 220, and a locking handle 230.

As shown in fig. 2, the semicircular flanges 210 are provided in a pair, and a circular insertion passage 211 is formed therebetween in a state of being closely attached to each other. A circular insertion passage 211 formed by a pair of semicircular flanges 210 (in consideration of the thickness of the closing member 220) is formed with a diameter a little larger than that of the subject's arm a. Therefore, in consideration of various subjects distinguished according to age, sex, race, and the like, it is preferable that the plurality of semicircular flanges 210 having diameters of the insertion channels 211 different from each other are manufactured and provided.
As shown in fig. 3, the semicircular flanges 210 are rotatably coupled to each other from the hinge portion 212. Therefore, in a state where one of the semicircular flanges 210 is coupled to the body 110 by the bolts B, the other one of the semicircular flanges can be rotated about the hinge portion 212 as an axis, thereby separating the insertion passages 211 from each other. In a state where one of the semicircular flanges 210 is rotated and the insertion passages 211 are spaced apart from each other, the arm a of the subject is inserted into the inner space 101 through the through hole 102.

The locking handle 230 is a structure that connects the semicircular flanges 210 to each other in a state where the insertion passage 211 is formed, and is disposed on the opposite side of the hinge portion 212 with reference to the semicircular flanges 210. As shown in fig. 2, in a state where the locking handle 230 is coupled to the semicircular flanges 210, the relative rotation between the semicircular flanges 210 is prevented. Although not shown in detail, the locking handle 230 may employ various well-known techniques for locking or unlocking an object that is opened or closed by rotation.
The closing member 220 is configured to be closely attached to the circumference of the arm a of the subject, and may be formed in a band shape of an elastically stretchable material such as rubber or silicone, and attached to the semicircular flanges 210 along the inner circumference of the insertion path 211. As shown in fig. 2, in a state where the pair of semicircular flanges 210 form the circular insertion passage 211 (a state where the locking handle 230 is connected to the semicircular flanges 210), the sealing member 220 is closely attached along the circumference of the arm a of the subject, whereby the internal space 101 is completely sealed from the outside.
As shown in fig. 1, the dust spraying unit 300 is a structure that sprays dust into the inner space 101, and includes a spraying pipe 310, a dust bucket 320, and an opening and closing valve 330.
The injection pipe 310 is configured to discharge the compressed gas containing the dust into the internal space 101, and is formed in a pipe shape and inserted into the internal space 101 through a hole of the body 110. The hole of the body 110 into which the injection pipe 310 is inserted is sealed. The injection pipe 310 is formed with a plurality of discharge ports 311 along a length direction thereof to discharge the compressed gas containing the dust.
The dust bucket 320 is a structure that stores artificial dust inside, and is externally connected to the injection pipe 310. The artificial dust stored in the dust bin 320 may be graphite powder (graphite power, CRETACOLOR) composed of carbon as a main component of fine dust. The graphite powder stored in the dust bucket 320 may be provided with about 1g of 1 subject.
Of course, the material of the artificial dust is not limited to graphite powder, and various materials can be selected from those that can be processed into suspended fine particles such as carbon powder (carbon powder). In addition, the amount of artificial dust stored in the dust bucket for testing at one time and the injection pressure can be variously changed by adjusting the test conditions.
The opening/closing valve 330 is a structure that opens and closes a pipe line (hereinafter, referred to as "injection pipe line 331") through which the compressed gas flows into the injection pipe 310, and is provided between the injection pipe line 331 and the dust bucket 320. The injection line 331 may be connected to a compressor (not shown) that generates compressed gas (compressed air).

The suction pipe 420 is a pipe for discharging the artificial dust flowing into the internal space 101, and is formed in a pipe shape and coupled to a hole of the main body 110. The suction pipes 420 are connected to the upper and lower portions of the body 110, respectively, and when the suction pump 410 is actuated, the artificial dust flowing into the inner space 101 is rapidly discharged to the suction pump 410 side through the suction pipes 420 connected to the upper and lower portions of the body 110. Although not shown, the suction pipes 420 may be provided with on-off valves (not shown), respectively.
As shown in fig. 1, the gas injection unit 500 is a structure that injects compressed gas into the inner space 101 to maintain the suspended state of the dust, and includes an opening and closing valve 510 and a discharge pipe 520.
The discharge pipe 520 is configured to discharge the compressed gas into the internal space 101, and is formed in a pipe shape and inserted into the internal space 101 through a hole in the body 110. The holes of the body 110 into which the spouting pipes 520 are inserted are sealed. The discharge pipe 520 is formed with a plurality of discharge ports 311 along the longitudinal direction thereof, respectively, to discharge the compressed gas. The ejection pipe 520 discharges the compressed gas at the lower portion of the body 110, thereby preventing the artificial dust ejected from the ejection pipe 310 from settling on the bottom surface.
The on-off valve 510 is configured to open and close a pipe (hereinafter referred to as a "discharge pipe 511") through which the compressed gas flows into the discharge pipe 510, and is provided between the discharge pipe 511 and the discharge pipe 520. The discharge pipe 511 may be connected to a compressor (not shown) that generates a compressed gas (compressed air).

Therefore, in a state where the pair of semicircular flanges 210 form the circular insertion passage 211 (a state where the locking handle 230 is connected to the semicircular flanges 210), the sealing member 220 can be closely attached to the circumference of the arm a of a subject having various arm a diameters such as age, sex, and race, and the internal space 101 is completely sealed from the outside.
At present, anti-pollution cosmetics (dust-proof or dust-proof product groups) are not cosmetic functional cosmetics unlike sunscreen agents which have been certified for sunscreen effects, and there is no separate certification standard.
In research rooms of enterprises and universities, the performance of anti-contamination cosmetics is tested by a method of spraying artificial dust using an injector after applying the anti-contamination cosmetics on the skin of a test subject, but the test methods are different, and thus the dust-proof effect cannot be objectively confirmed at present.
In the research rooms of enterprises and universities, even if the testee wears a dust mask while spraying artificial dust using an injector, the whole body of the testee is inevitably contaminated with fine dust after the end of the test, which neglects the adverse effect on the respiratory organs of the testee.
In the method S100 for testing dustproof performance of a cosmetic according to the present invention, the device 10 for testing dustproof performance of a cosmetic is used, and thus, not only can reliable quantitative and qualitative data be calculated in a dustproof performance test, but also the respiratory organs of a subject can be completely protected from artificial dust even without a dustproof mask.
As shown in fig. 5, the method S100 for testing dust-proof property of cosmetics according to the present invention includes a preparation step S110, an insertion step S120, an injection step S130, a cleaning step S140, a pull-out step S150, and a measurement step S160.
The preparation step S110 is a step of applying a cosmetic on the arm a of the subject, which includes an application step S111 and a waiting step S112.
In the application step S111, after dividing the area to which the cosmetic is applied on the arm a of the subject into a plurality of, the test cosmetic C1 and the control cosmetic C2 are applied, respectively. The area of the applied cosmetic was about 3cmx4cm, and a plurality of cosmetic patches were formed on the arm A of the subject. In fig. 2, it is shown that the area to which the cosmetics were applied was divided into 2 and the test cosmetics C1 and the control cosmetics C2 were applied, respectively.
The waiting step S112 is a step of waiting for a period of time during which the test cosmetic C1 and the control cosmetic C2 are absorbed by the skin, and the waiting time is about 15 minutes. In the waiting step S112, the temperature and humidity can be adjusted to various variables by adjusting the temperature and humidity of the laboratory.
After the end of the waiting step S112, an inserting step S120 is performed. The insertion step S120 is a step of inserting the subject' S arm a into the inner space 101 of the chamber 100 isolated from the outside through the insertion passage 211 of the insertion unit 200.
As shown in fig. 3, in the insertion step S120, one of the semicircular flanges 210 is set in a state of being coupled to the body 110 by the bolts B, and the other is set in a state of being rotated about the hinge portion 212 to separate the insertion passages 211 from each other.
In the insertion step S120, the arm a of the subject is inserted into the internal space 101 through the through hole 102 in a state where the insertion passages 211 are spaced from each other, and in this state, the semicircular flange 210 is rotated to closely attach the sealing member 220 along the circumference of the arm a of the subject. After that, the semicircular flange 210 is connected by the locking handle 230, and at this time, the internal space 101 is kept in a completely sealed state from the outside.
As shown in fig. 4, in the case where sealing member 220 includes sealing member 221 and bellows 222, a compressor (not shown) is started in a state where semicircular flange 210 is connected by lock handle 230, and compressed gas is injected into bellows 222 through connection pipe T, and bellows 222 is expanded by the injection of compressed gas and is closely attached to the circumference of arm a of the subject.
The inserting step S120 is ended, and the injecting step S130 is performed. The spraying step S130 is a step of spraying dust to the inner space 101, and includes a dust spraying step S131 and a levitation holding step S132.
The dust spraying step S131 is a step of spraying the compressed gas to the internal space 101 through the discharge port 311 of the spraying pipe 310 together with the dust through the dust bucket 320 while opening the opening and closing valve 330 of the dust spraying unit 300. As described above, the artificial dust stored in the dust bin 320 may be graphite powder (graphite power, CRETACOLOR) composed of carbon as a main component of fine dust. The graphite powder stored in the dust bucket 320 may be provided with about 1g of 1 subject.
Of course, the material of the artificial dust is not limited to graphite powder, and various materials can be selected from those that can be processed into suspended fine particles such as carbon powder (carbon powder). In addition, the amount of artificial dust stored in the dust bucket for one test and the injection pressure can be variously changed by adjusting the test conditions.
In the dust spraying step S131, the artificial dust stored in the dust bin 320 is uniformly sprayed through the plurality of discharge ports 311 in the upper portion of the inner space 101, and the artificial dust suspended in the inner space 101 is slowly adsorbed on the test cosmetic C1 and the control cosmetic C2 coated on the arm a. After the dust spraying step S131, the test makeup C1 and the control makeup C2 were exposed to artificial dust during a certain set time period before the cleaning step S140.
However, the artificial dust uniformly sprayed on the upper portion of the internal space 101 in the dust spraying step S131 may gradually fall down by gravity during a set time, and a density deviation of the artificial dust between the upper and lower portions of the internal space 101 may increase as time passes, which may become a variable of the test data.
The levitation-holding step S132 is a step of opening the opening and closing valve 510 of the gas injection unit 500 and injecting the compressed gas into the internal space 101 through the injection pipe 520, and the levitation-holding step S132 is continuously or periodically performed after the dust injection step S131 and before the cleaning step S140.
The ejection pipe 520 is disposed at the lower portion of the internal space 101 and discharges the compressed gas through the plurality of discharge ports 311, so that the artificial dust settled at the lower portion of the internal space 101 can be resuspended to the upper side, and thus the density of the artificial dust according to the height in the internal space 101 is maintained uniform after the dust spraying step S131 and before the cleaning step S140.
The cleaning step S140 is a step of discharging the dust in the internal space 101 to the outside again after the set time is over, and the artificial dust suspended in the internal space 101 is discharged to the outside through the suction pipe 420 connected to the suction pump 410 while being kept in a suspended state by the compressed gas injected into the internal space 101 through the ejection pipe 520. That is, the levitation holding step S132 is performed until the cleaning step S140 is ended.
The suction pipes 420 are connected to the upper and lower portions of the body 110, respectively, and when the suction pump 410 is actuated, the artificial dust flowing into the inner space 101 is rapidly discharged to the suction pump 410 side through the suction pipes 420 connected to the upper and lower portions of the body 110.
When the cleaning step S140 is finished, the pull-out step S150 is performed. The drawing step S150 is a step of drawing the arm a of the subject to the outside, and after one of the semicircular flanges 210 is rotated about the hinge portion 212 as an axis to separate the insertion channels 211 from each other, the arm a of the subject is drawn to the outside.
As shown in fig. 4, in the case where the sealing member 220 includes a sealing member 221 and a bellows 222, in a state where the locking handle 230 is connected to the semicircular flange 210, compressed gas is discharged through a discharge valve (not shown) formed on the connection pipe T, and then the arm a of the subject is drawn out.
After the subject's arm a is withdrawn, the insertion channel 211 is blocked by the blocking plate 240. The blocking plate 240 is formed as a circular disk having a larger diameter than the insertion passage 211, and as shown in fig. 1, the blocking plate 240 blocks the insertion passage 211 in a state of being positioned between the closing member 220 and the body 110.
The measurement step S160 is a step of measuring the brightness of the cosmetic in the captured image after capturing the arm a of the subject, and various known techniques can be employed for the capturing device and the brightness measurement software used in the measurement step S160. As an example, the subject's arm A may be captured by VISIA-CR (Canfield Imaging Systems), and the captured Image may be captured by Image-
plus performs a brightness analysis.
Adopting Image-
plus, after a specific region is specified on the image, the Intensity value (0 to 255) of the region can be output. The Intensity value refers to the luminance, and the closer a particular region is to black, the smaller the Intensity value. Therefore, the larger the Intensity value of the cosmetic application site is, the less the artificial dust is adsorbed, and thus it can be confirmed that the dust is adsorbedAn adsorption preventing effect.
According to the present invention, it is possible to provide a dust-proof performance testing apparatus for cosmetics and a performance testing method using the same, in which the spraying step and the cleaning step are performed in a state where the arm of the subject is isolated in the inner space of the chamber in the inserting step, thereby not only completely protecting the respiratory organ of the subject from the influence of artificial dust, but also maintaining the density of the artificial dust suspended in the air to be uniform around the arm coated with the cosmetics.
While specific embodiments of the present invention have been described and illustrated, it is obvious to those skilled in the art that the present invention is not limited to the embodiments described above, and various modifications and variations can be made without departing from the scope of the concept of the present invention. Therefore, such modifications and variations cannot be individually understood from the technical idea or viewpoint of the present invention, and the modified embodiments should fall within the scope of claims of the present invention.
