Description

Technical Field

[0001] The present disclosure relates to a makeup antibacterial puff treated with an antibacterial substance, wherein the antibacterial substance includes one or more selected from the group consisting of Hydroxyacetophenone and cetylpyridinium chloride, and a method for manufacturing the same.

Background Art

[0002] Makeup cosmetics are cosmetics that enhance the skin. In particular, makeup liquid cosmetics are widely used in recent years because they spread better on the skin than in powder form. Such makeup liquid cosmetics were conventionally dispensed by hand and applied to the facial area, but there were inconveniences such as having to wash the hands with tissue or water after makeup, so a makeup puff was developed to eliminate the need to use hands.

[0003] As the puff, porous materials such as NBR (Nitrile butadiene rubber), SBR (Styrene butadiene rubber), natural rubber, flocking, Rubycell (wet urethane), cotton velour, and PVA (Polyvinyl alcohol) are used. During use, the liquid cosmetic is carried in the porous structure and can be transferred to the skin surface. Such a puff has the convenience of use in that it can dispense an appropriate amount of the liquid cosmetic from the cosmetic container and transfer the cosmetic to the skin surface, enabling makeup without getting the cosmetic on the hands.

Summary of the Invention

Problems to be Solved by the Invention

[0004] On the one hand, the face is prone to the growth of microorganisms due to the secretion of sebum and sweat, exposure to dust during standby, and contact with hands contaminated by microorganisms. Therefore, the puff that comes into contact with cosmetics is supplied with humidity and nutrients from the cosmetics. When applying the cosmetics to the face, the puff comes into direct contact with the skin surface of the face, and microorganisms may transfer to the puff. The puff contaminated with microorganisms is stored in a cosmetic container, and the sealed bag for storing the cosmetic container or the warm indoor space where the dressing table is located has heat retention. Since the cosmetics adhering to the used puff are liquid and contain water, such a complex environment creates an environment that provides the temperature, humidity, and nutrients conducive to the growth of microorganisms on the puff. When such a puff is used again, the cosmetics in contact are likely to be contaminated by microorganisms, and the contaminated cosmetics may cause skin problems. Moreover, if the produced puff is exposed to a high-temperature and high-humidity environment during the distribution and storage processes before being provided to consumers, there is a possibility that microorganisms will grow on the puff, and the puff has the problem of losing its commercial value.

[0005] In order to prevent microbial contamination, preservatives are used in cosmetics. However, when dispensing and using cosmetics with a puff, the preservative of the cosmetics remaining on the puff is exposed to the air, and volatile substances such as moisture evaporate, resulting in a state where its preservative power cannot be exerted. Therefore, relying solely on the preservatives contained in cosmetics cannot prevent microbial contamination caused by puff use. Therefore, it is necessary to develop a puff with an antibacterial function so as to suppress the growth of microorganisms during puff use.

[0006] For this purpose, puff manufacturers have made efforts to perform antibacterial treatment on puffs to suppress microorganisms. Generally, a puff is a beauty tool for conveniently using cosmetics and is only classified and managed as an industrial product and is not regulated by the Cosmetics Act. For this reason, puff manufacturers have obtained antibacterial effects by using antibacterial substances not included in the list of preservatives (antiseptics) permitted for cosmetics. However, such antibacterial substances do not ensure safety for the skin and often do not exhibit antibacterial effects.

[0007] Therefore, in order to ensure the safety for the skin, the present inventors have developed a makeup antibacterial puff using a cosmetic raw material permitted for use by the Cosmetics Act or a raw material that requires usage restrictions (e.g., preservatives).

In the field of the present disclosure, this level of approximation is appropriate unless a value specifically requires a narrower range.

[0036] Hereinafter, embodiments of the present disclosure will be described in detail.

[0037] One embodiment of the present disclosure is a cosmetic antibacterial puff treated with an antibacterial substance, wherein the antibacterial substance comprises one or more selected from the group consisting of Hydroxyacetophenone and cetylpyridinium chloride.

[0038] In recent years, the use of chemical preservatives as raw materials for cosmetics has been avoided, and diols are used as alternative substances. Diols have the effect of reducing the water activity of cosmetic dosage forms and suppressing the growth of microorganisms. However, since the antibacterial power against microorganisms is lower than that of chemical preservatives, an excessive amount must be used to exhibit antibacterial power when used in puffs. However, it is difficult to adhere an excessive amount of diols to the puff, and when coated on the puff, the physical properties of the puff and the cosmetic delivery functionality may decrease, which is inconvenient for application to the puff.

[0039] Hydroxyacetophenone is a cosmetic raw material and is classified as an antioxidant, and is known to have a high safety level for the skin, but has never been used as an antibacterial substance in cosmetic puffs. Cetylpyridinium chloride is a cationic compound that inhibits bacteria and other microorganisms and is classified as a preservative for cosmetics.

[0040] In one embodiment, the antimicrobial substance of the present disclosure may further include one or more selected from the group consisting of phenoxyethanol, sorbic acid, and a sequestering agent.

[0041] Phenoxyethanol is used in cosmetics and serves as an antiseptic and bactericidal preservative. Sorbic acid inhibits the growth of microorganisms and is used as a preservative in cosmetics and processed foods.

[0042] When the antimicrobial substance further includes one or more selected from the group consisting of hydroxyacetophenone, cetylpyridinium chloride, phenoxyethanol, and sorbic acid is included in the puff, the antimicrobial effect of the puff is significantly improved.

[0043] In one embodiment, the sequestering agent may be, but is not limited to, EDTA (ethylenediaminetetraacetate), pentasodium pentetate, disodium EDTA, calcium disodium EDTA, trisodium EDTA, or tetrasodium EDTA.

[0046] In one embodiment, the absorption puff layer of the present disclosure may include Rubycell.

[0047] Although general polyurethane foam has the property of absorbing water and swelling, Rubycell, which is a wet urethane, does not have the property of foaming in water and absorbing water during production, and thus easily transfers the cosmetic composition to the skin surface.

[0048] In one embodiment, Rubycell may have a density of 0.01 to 0.3 g / cm 3 .

[0049] In one embodiment, Rubycell may have a density of 0.01 g / cm 3 or more, 0.05 g / cm 3 or more, 0.1 g / cm 3 or more, 0.15 g / cm 3 or more, 0.3 g / cm 3 or less, 0.25 g / cm 3 or less, or 0.2 g / cm 3 or less, but is not limited thereto.

[0051] In one embodiment, Rubycell may have a tensile strength of 100 kgf / cm 2150 kgf / cm or more 2 200 kgf / cm or more 2 250 kgf / cm or more 2 300 kgf / cm or more 2 500 kgf / cm or more 2 450 kgf / cm or less 2 400 kgf / cm or less 2 or 350 kgf / cm or less 2 It may have a tensile strength of the above or less, but is not limited thereto.

[0052] In one embodiment, the diameter of the pores of the ruby cell may be 5 to 500 μm.

[0053] In one embodiment, the diameter of the pores of the ruby cell may be 5 μm or more, 10 μm or more, 50 μm or more, 100 μm or more, 150 μm or more, 200 μm or more, 250 μm or more, 500 μm or less, 450 μm or less, 400 μm or less, 350 μm or less, or 300 μm or less, but is not limited thereto.

[0054] In one embodiment, the ruby cell may have an Asker hardness scale F type standard of 10 to 100.

[0055] In one embodiment, the ruby cell may have an Asker hardness scale F type standard of 10 or more, 20 or more, 30 or more, 40 or more, 50 or more, 100 or less, 90 or less, 80 or less, 70 or less, or 60 or less, but is not limited thereto.

[0056] In one embodiment, the buffer puff layer of the antibacterial cosmetic puff can play a role of smoothly adhering to the skin surface while containing air. The buffer puff layer may include any one or more selected from polyurethane foam with a porous structure, polyether, polyester, styrene-butadiene rubber, natural rubber, nitrile butadiene rubber, thermoplastic polyurethane elastomer (TPU), polyurethane sheet, synthetic leather, chloroprene rubber (CR), polyvinyl chloride, polyethylene, and ethylene-vinyl acetate butyl rubber (EVA), but is not limited thereto.

[0057] In one embodiment, the outer skin layer of the antibacterial cosmetic puff can play a role of maintaining the puff shape. The outer skin layer may be made of materials such as polyurethane foam, urethane sheet, synthetic leather, rubber, etc., but is not limited thereto.

[0058] In one embodiment, the antibacterial cosmetic puff of the present disclosure may further include one or more layers. The additional layer may be provided between any two of the absorption puff layer, the buffer puff layer, and the outer skin layer.

[0059] In one embodiment, the additional layer of the antibacterial cosmetic puff of the present disclosure may include any one or more materials selected from acrylic, urethane, epoxy, silicone, latex, and thermoplastic resin, but is not limited thereto.

[0065] In one embodiment, the composition of the present disclosure may further contain one or more selected from the group consisting of phenoxyethanol and sorbic acid.

[0066] In one embodiment, the composition of the present disclosure may independently contain one or more selected from the group consisting of phenoxyethanol and sorbic acid in an amount of 0.01 to 1.2% by weight based on the total weight of the composition.

[0067] In one embodiment, based on the total weight of the composition, phenoxyethanol may be contained, for example, in an amount of 0.01% by weight or more, 0.05% by weight or more, 0.1% by weight or more, 0.2% by weight or more, 0.3% by weight or more, 0.4% by weight or more, 0.5% by weight or more, 0.6% by weight or more, 1.2% by weight or less, 1.1% by weight or less, 1.0% by weight or less, 0.9% by weight or less, 0.8% by weight or less, or 0.7% by weight or less, but is not limited thereto.

[0069] In one embodiment, the composition of the present disclosure may further include a sequestering agent.

[0070] In one embodiment, the sequestering agent may be, but is not limited to, EDTA (ethylenediaminetetraacetate), pentasodium pentetate, disodium EDTA, calcium disodium EDTA, trisodium EDTA, or tetrasodium EDTA.

[0071] In one embodiment, the composition of the present disclosure may further include a sequestering agent at 0.01 - 2 wt% based on the total weight of the composition.

[0075] In one embodiment, the treatment step may include ultrasonic treatment.

[0076] As a method for introducing an antibacterial substance into a cosmetic puff, simply a method of putting a cosmetic puff into a solution containing an antibacterial substance and impregnating it or heating it for impregnation has been used. However, when simply impregnating a cosmetic puff into a solution containing an antibacterial substance, there is a problem that the antibacterial substance is not uniformly introduced into the cosmetic puff and the desired antibacterial power cannot be obtained. Therefore, when a cosmetic puff is put into a manufactured composition containing an antibacterial substance and ultrasonic treatment is performed, the antibacterial substance is uniformly distributed in the cosmetic puff due to the generation of fine vibrations.

[0077] In one embodiment, the ultrasonic treatment may be performed at a frequency of 10 to 30 KHz and an intensity of 1000 to 3000 W.

[0078] In one embodiment, the frequency of the ultrasonic treatment may be 10 KHz or higher, 11 KHz or higher, 12 KHz or higher, 13 KHz or higher, 14 KHz or higher, 15 KHz or higher, 16 KHz or higher, 17 KHz or higher, 18 KHz or higher, 19 KHz or higher, 20 KHz or higher, 30 KHz or lower, 29 KHz or lower, 28 KHz or lower, 27 KHz or lower, 26 KHz or lower, 25 KHz or lower, 24 KHz or lower, 23 KHz or lower, 22 KHz or lower, or 21 KHz or lower, but is not limited thereto.

[0079] In one embodiment, the intensity of the ultrasonic treatment can be 1000 W or more, 1100 W or more, 1200 W or more, 1300 W or more, 1400 W or more, 1500 W or more, 1600 W or more, 1700 W or more, 1800 W or more, 1900 W or more, 2000 W or more, 3000 W or less, 2900 W or less, 2800 W or less, 2700 W or less, 2600 W or less, 2500 W or less, 2400 W or less, 2300 W or less, 2200 W or less, or 2100 W or less, but is not limited thereto.

[0080] In one embodiment, the ultrasonic treatment may be performed for a total of 5 to 30 minutes.

[0081] In one embodiment, the ultrasonic treatment can be performed for a total of 5 minutes or more, 10 minutes or more, 15 minutes or more, 30 minutes or less, 25 minutes or less, or 20 minutes or less, but is not limited thereto.

[0082] In one embodiment, the treatment step of the present disclosure may further include drying the composition containing the antibacterial substance at a constant temperature of 40 to 50 °C after impregnating the makeup puff with the composition containing the antibacterial substance.

[0083] In one embodiment, the treatment step of the present disclosure may be performed on any one or more of the absorption puff layer, buffer puff layer, and outer skin layer of the makeup puff.

[0084] In one embodiment, any one or more of the absorption puff layer, buffer puff layer, and outer skin layer may be impregnated with the composition containing the antibacterial substance, either independently or in combination.

[0085] One embodiment of the present disclosure is a makeup antibacterial puff manufactured by the method for manufacturing the makeup antibacterial puff of the present disclosure.

[0086] In one embodiment, the makeup antibacterial puff may contain one or more selected from the group consisting of hydroxyacetophenone and cetylpyridinium chloride.

[0087] In one embodiment, the cosmetic antibacterial puff may further include one or more selected from the group consisting of phenoxyethanol, sorbic acid, and a sequestering agent.

[0088] In one embodiment, the sequestering agent may be, but is not limited to, EDTA (ethylenediaminetetraacetate), Pentasodium Pentetate, disodium EDTA, Calcium disodium EDTA, trisodium EDTA, or tetrasodium EDTA.

[0089] In one embodiment, the cosmetic antibacterial puff includes an absorption puff layer that absorbs a cosmetic during use; a buffer puff layer provided on the absorption puff layer; and an outer skin layer provided on the buffer puff layer, and the antibacterial substance may be treated and contained in the absorption puff layer.

[0090] In one embodiment, the absorption puff layer of the cosmetic antibacterial puff can play a role in sucking in a liquid cosmetic composition. The absorption puff layer may include any one or more selected from among Rubycell having a porous structure, polyurethane foam (PU), styrene-butadiene rubber (SBR), natural rubber, nitrile butadiene rubber (NBR), flocking, Cotton velour, and polyvinyl alcohol (PVA), but is not limited thereto.

[0091] In one embodiment, the absorption puff layer may include Rubycell.

[0093] In one embodiment, the outer skin layer can serve to maintain the form of the puff. The outer skin layer may be made of materials such as polyurethane foam, urethane sheet, synthetic leather, rubber, etc., but is not limited thereto.

[0094] In one embodiment, the cosmetic antibacterial puff may further include one or more layers. The additional layer may be provided between any two of the absorption puff layer, the buffer puff layer, and the outer skin layer.

Any material that can bond the layers to maintain the form of the puff or can serve a waterproof role is applicable.

[0096] Hereinafter, embodiments of the present disclosure will be described in detail. However, the following examples are provided only to make the present disclosure easier to understand and do not limit the content of the present disclosure.

[0097] <Manufacturing Example of Cosmetic Antibacterial Puff>

[0098] The antibacterial substances were weighed according to Table 1 below. The control group did not treat the antibacterial substances at all. Examples 1 and 2 and Comparative Examples 1 to 6 contained only one kind of antibacterial substance. Examples 3 to 6 and Comparative Examples 7 to 9 contained two kinds of antibacterial substances. Examples 7 to 9 and Comparative Example 12 were designed to contain three kinds of antibacterial substances.

[0099] Purified water was added to a thermostatic water bath equipped with a stirrer, and the temperature was adjusted to 40°C to 70°C. While gradually adding the weighed antibacterial substances to the heated purified water, it was stirred until the antibacterial substances melted, and then stirred again after a certain period of time so that the antibacterial substances were completely dissolved.

[0100]

Table 1

[0101] Then, into a thermostatic water bath maintained at a temperature of 40°C to 50°C containing the composition containing the antibacterial substances, a ruby cell (absorption puff layer) having a density of 0.11 to 0.14 g / cm 3 , a tensile strength of 300 to 360 kgf / cm 2 , a pore diameter of 25 to 400 μm, and an Asker hardness of type F standard of 25 to 50 was put in. The composition containing the antibacterial substances was ultrasonically treated at 20 KHz and 2000 W for 20 minutes so that the antibacterial substances could be evenly distributed in the ruby cell. The treated ruby cell was taken out from the composition and placed in a thermostatic dryer at 40°C to 50°C and dried for 4 to 5 hours. A polyester foam was placed on the dried ruby cell as a buffer puff layer and joined, and a urethane sheet was placed on the polyester foam as an outer skin layer and joined to manufacture a cosmetic antibacterial puff.

[0102] <Experimental Example 1. Evaluation of the antibacterial effect of the cosmetic antibacterial puff>

[0103] (1) Antibacterial power test against bacteria

[0104] The antibacterial activity test against bacteria was conducted in accordance with the plate count method (KS K 0693 test method), and two types of test bacteria, Escherichia coli (E. coli, a type of coliform bacteria) (accession number: ATCC8739) and Staphylococcus aureus (S. aureus, a type of staphylococcus) (accession number: ATCC 6538), were used. Specifically, the test bacteria (1±0.3)×10 5 CFU / ml was inoculated at 0.2 ml on each puff of the cosmetic and on the surface in contact with the skin, placed in a sterilized container with a lid, and cultured in an incubator at 37±1°C. The viable cell count of the puff was measured at 0 hours and 18 hours and is shown in Table 2.

[0105] 1) Treatment with one antibacterial substance

[0106] When treated with one antibacterial substance, Example 1 treated with hydroxyacetophenone and Example 2 treated with cetylpyridinium chloride showed particularly high antibacterial effects against bacteria compared to the control group without the antibacterial substance treatment (Table 2).

[0107] 2) Treatment with two antibacterial substances

[0108] Based on the result that the example treated with hydroxyacetophenone showed the best antibacterial effect, when hydroxyacetophenone was mixed and treated with one of the other seven antibacterial substances respectively, the cases of using cetylpyridinium chloride (Example 3), phenoxyethanol (Example 4), sorbic acid (Example 5), and EDTA (Example 6) in combination showed better antibacterial effects compared to the cases of other two-substance combinations (Table 2).

[0109] 3) Treatment with three antibacterial substances

[0110] Among the examples of using two substances in combination, when hydroxyacetophenone and cetylpyridinium chloride, which showed the best effect, were mixed and treated with one of the remaining six antibacterial substances respectively, the cases of using phenoxyethanol (Example 7), sorbic acid (Example 8), and EDTA (Example 9) in combination showed better effects compared to the cases of other three-substance combinations (Table 2).

[0111] 4) Comparison with commercially available antibacterial puffs

[0112] A commercially available antibacterial puff for cosmetics (Comparative Example 13) was obtained, and the antibacterial activity test against the bacteria was carried out in the same manner. As a result, although an antibacterial effect was shown compared to the control group that had not been treated with the antibacterial substance, Comparative Example 13 showed a lower antibacterial effect compared to Examples 1 to 9 (Table 2, Figures 2, and 3).

[0113] (2) Antibacterial activity test against fungi - Plate counting method

[0114] Aspergillus brasiliensis (Aspergillus niger) (Accession number: ATCC 16404) was used as the test bacterium by the plate counting method (KS K ISO 13629-2). Specifically, on the cosmetic and the surface of the puff that contacts the skin, 0.2 mL of a spore suspension (1 to 3)×10 5 cells / ml was inoculated, placed in a sterilized container with a lid, and cultured in an incubator at 30±2°C for 0 hours and 48 hours. Then, the viable cell count of the puff was measured and described in Table 2.

[0115] 1) Treatment with one antibacterial substance

[0116] When treated with one antibacterial substance, Example 1 treated with hydroxyacetophenone and Example 2 treated with cetylpyridinium chloride showed particularly high antibacterial effects compared to the control group that had not been treated with the antibacterial substance (Table 2).

[0117] 2) Treatment with two antibacterial substances

[0118] Based on the result that the example treated with hydroxyacetophenone showed the best antibacterial effect, when hydroxyacetophenone was mixed and treated with one of the other seven antibacterial substances respectively, the cases of using cetylpyridinium chloride (Example 3), phenoxyethanol (Example 4), sorbic acid (Example 5), and EDTA (Example 6) showed superior antibacterial effects compared to the cases of mixing and treating with other two kinds (Table 2).

[0119] 3) Treatment with three antibacterial substances

[0120] When one of the remaining six antibacterial substances was mixed and treated with hydroxyacetophenone and cetylpyridinium chloride, which showed the best effect among the examples of using two substances in combination, almost the same effect was shown in all cases (Table 2).

[0121] 4) Comparison with commercially available antibacterial puffs for cosmetics

[0122] A commercially available antibacterial puff for cosmetics (Comparative Example 13) was obtained, and the antibacterial activity test against the fungus was carried out in the same manner. As a result, it showed an antibacterial effect compared to the control group not treated with antibacterial substances, but a lower antibacterial effect compared to Examples 3 - 5, Example 7, Example 9, Comparative Example 7, Comparative Example 10, and Comparative Example 12 (Table 2 and Figure 4).

[0123] (3) Antibacterial activity test against fungi - AATC TM30 test method

[0124] Aspergillus brasiliensis (Aspergillus niger) (Accession number: ATCC 16404) was used as the test fungus. Specifically, in order to confirm the degree to which the fungus in the outer skin layer spreads to the puff absorption layer, the outer skin layer (the part with the puff handle) was brought into contact with the culture medium inoculated with the spore suspension for the control group and Example 3, and the degree to which the mold spores spread to the puff was measured 20 days and 28 days after culturing at 25°C to qualitatively evaluate the antibacterial activity, which was described in Table 2 with scores from 0 (no antibacterial effect) to 5 (extremely high antibacterial effect). Example 3, which was treated with both hydroxyacetophenone and cetylpyridinium chloride, showed an excellent antibacterial effect compared to the control group not treated with antibacterial substances (Table 2, Figure 5, and Figure 6).

[0125]

Table 2

[0126] <Experimental Example 2. Physical property evaluation of antibacterial puffs for cosmetics>

[0127] For the antibacterial puff control group, Example 3, and Comparative Example 13, the physical properties with respect to hardness, tensile strength, and elongation rate were measured and evaluated, and the results are shown in Table 3.

[0128] Hardness was measured using an Asker (manufactured by Asker) durometer hardness (DUROMETER HARDNESS) measuring instrument (Type F). The area of the pressure foot in contact with the sample was 80 mm, and the sample was cut into 200 mm * 200 mm for use. Hardness was measured by placing the hardness tester on the test piece under constant temperature and humidity conditions (20 - 25 °C, 40 - 60%). The result values are displayed in arbitrary units (Arbitrary unit) from 1 to 100. Tensile strength was measured under constant temperature and humidity conditions (20 - 25 °C, 40 - 60%). After cutting the antibacterial - treated ruby cell into a standard of 10 mm * 50 mm and removing the outer skin layer at the upper end, the upper and lower ends of the 10 - mm part of the sample were grasped and pulled at a constant speed, and the maximum load W at which the test piece breaks and the original cross - sectional area S of the sample were measured. It was measured with an Instron testing instrument (3344), and the value of tensile strength was recorded in kgf / cm 2 and recorded. The said tensile strength was measured in accordance with JIS K 6400 - 5:2012. Elongation rate: After cutting the coated area into a standard of 10 mm * 50 mm and removing the outer skin layer at the upper end, the upper and lower ends of the 10 - mm part of the sample were grasped, and the length L during which the sample breaks by the said tensile test was measured. When the length at the starting point of pulling is L o is used, the elongation rate can be expressed by the following formula. The said elongation rate was measured in accordance with JIS K 6400 - 5:2012.

[0129] Elongation rate (%) = {(L - L o ) / L o} * 100 (Formula 1)

[0130] It was confirmed that Example 3 treated with the antibacterial substance had excellent physical properties compared to the control group not treated with the antibacterial substance, and Example 3 showed physical properties similar to those of commercially available Comparative Example 13 (Table 3).

[0131]

Table 3

[0132] <Experimental Example 3. Evaluation of the Cosmetic Transfer Rate of Antibacterial Puffs>

[0133] The transfer rate of the antibacterial puff for cosmetics was calculated by the following formula after measuring the absorption amount and discharge amount of the cosmetic. If the value was 30% or more, it was evaluated that the transfer rate of the cosmetic was excellent, and the results are shown in Table 4.

[0134] Transfer rate (%) = (Amount of the cosmetic composition taken by the puff discharged to the application target (discharge amount) / Amount of the cosmetic composition absorbed by the puff (absorption amount)) × 100 (Formula 2)

[0135] Example 3 had an excellent transfer ability compared to the control group that did not treat the antibacterial substance and showed a transfer ability similar to that of commercially available Comparative Example 13 (Table 4).

[0136]

Table 4

[0137] <Experimental Example 4. Evaluation of the Use Feeling of Antibacterial Puffs for Cosmetics>

[0138] Twenty users aged from their 20s to 40s were asked to evaluate the use feeling and cushion feeling of the cosmetic puffs of the control group, Example 3, and Comparative Example 13. The use feeling refers to the overall touch felt on the skin surface when applying the cosmetic with the cosmetic puff, and the cushion feeling refers to the degree of elasticity felt when applying a certain pressure after contacting the cosmetic puff with the skin surface. They were evaluated according to the following evaluation criteria. The average values are shown in Table 5 below.

[0139] <Evaluation Criteria for Use Feeling> 1 point: Bad use feeling 2 points: Ordinary use feeling 3 points: Good use feeling 4 points: Very good use feeling

[0140] <Evaluation Criteria for Cushion Feeling> 1 point: Bad cushion feeling 2 points: Ordinary cushioning feeling 3 points: Good cushioning feeling
