Description

Title of the invention: COSMETIC SKINCARE AND PROCESS Technical field

[0001] The present invention relates to a cosmetic device and process, both useful for skin care. CONTEXT OF THE INVENTION

[0002] Excessive secretion of fatty / waxy substances by the sebaceous glands is responsible for the oily appearance of the skin. Sebaceous glands are mainly present on the face and scalp, although they are distributed over all areas of the skin except the palms of the hands and the soles of the feet. Sebum contains triglycerides, waxes, squalene, and metabolites from fat-producing cells. Although sebum keeps hair and skin supple, excess sebum can contribute to the concentration of keratinized cells at the opening of the sebaceous follicles on the skin's surface, causing constriction of the follicular opening and resulting in a keratin plug. This can lead to blackheads, closed comedones, significant irritation, redness, tissue damage, and acne. Here, the term comedones refers to both closed comedones and blackheads.

[0003] There are a number of commercially available products that aim to control sebum and comedones on the skin.

[0004] The use of mineral clays as medicinal and cosmetic tools for sebum control has long been popular in the market. Clays are used to absorb excess oil or sebum, impurities, and toxins from the skin while exfoliating the skin and improving skin circulation.

[0005] Document WO 2015 / 075143 describes a body composition with an applicator comprising at least one clay and at least one water-soluble polymer, which can be supplied in the form of a face mask.

[0006] Document WO 2024 / 034324 describes a sheet cosmetic product comprising a water-soluble or water-dispersible substrate, and a coating layer on the substrate, wherein the coating layer comprises at least one clay and at least one water-soluble binder.

[0007] On the other hand, pore cleansing strips or packs, which are intended to remove a keratin plug from the pores of the skin and contain a water-soluble polymer such as polyvinyl alcohol, have also long been popular on the market. These classic pore cleansing strips or packs are useful for removing blackheads from the skin.

[0008] However, the conventional pore cleansing strips or packs above require a lot of force to be pulled off the skin and, consequently, they tend to cause pain and / or skin damage when pulled off the skin. DISCLOSURE OF THE INVENTION

[0036] [Fig-1] Fig. 1 represents one embodiment of the necessary item used in the cosmetic process according to the present invention. Best embodiment of the invention

[0037] After diligent research, the inventors surprisingly discovered that a combination of an article comprising at least one coating layer disposed on a substrate, comprising at least one clay and at least one water-soluble binder, and a composition comprising at least one cationic polymer and at least one non-ionic polymer, can control sebum on the skin and eliminate skin comedones with reduced pain and / or reduced skin damage.

[0038] The expression "controlling sebum" here includes reducing the amount of sebum on the skin and / or delaying the increase in the amount of sebum on the skin over time.

[0039] Thus, the present invention relates to a cosmetic necessity and process based on the above combination.

[0040] The necessary components according to the present invention comprise:

[0041] (1) at least one article, comprising

[0042] (a) at least one substrate and

[0044] (2) at least one composition comprising

[0045] (i) at least one cationic polymer and

[0046] (ii) at least one non-ionic polymer.

[0047] The cosmetic process according to the present invention comprises the following steps:

[0048] (1) application to the skin (2) of at least one composition comprising

[0049] (i) at least one cationic polymer and

[0050] (ii)) at least one non-ionic polymer;

[0051] (2) application to the skin after step (1) of at least one article comprising

[0052] (a) at least one substrate and

[0053] (b) at least one coating layer disposed on the substrate comprising (bl) at minus one clay and (b2) at least one water-soluble binder;

[0054] (3) holding (1) article on the skin; and

[0055] (4) tearing off the (1) article of the skin.

[0056] The necessary and cosmetic process according to the present invention can control sebum on the skin and eliminate skin comedones with reduced pain and / or reduced skin damage.

[0057] The necessary cosmetic procedure according to the present invention will be explained in more detail below. [Necessary]

[0058] The necessary components according to the present invention comprise:

[0059] (1) at least one article, comprising

[0060] (a) at least one substrate and

[0061] (b) at least one coating layer disposed on the substrate comprising (bl) at minus one clay and (b2) at least one water-soluble binder and

[0062] (2) at least one composition comprising

[0063] (i) at least one cationic polymer and

[0064] (ii) at least one non-ionic polymer.

[0065] The device according to the present invention can control sebum on the skin and eliminate skin comedones with reduced pain and / or reduced skin damage.

[0066] The device according to the present invention can reduce the amount of sebum on the skin and / or delay the increase in the amount of sebum on the skin over time.

[0067] When the (1) article is applied to skin that has been treated with the (2) composition, the comedones on the skin can adhere well to the (1) article. Thus, by removing the (1) article from the skin by peeling it off, the comedones can also be effectively removed from the skin.

[0068] Furthermore, the force required to remove the (1) article from the skin is not as high as that of conventional cosmetic products used to remove blackheads. Therefore, the article according to the present invention can remove blackheads from the skin with reduced pain and / or reduced skin damage.

[0069] The necessary element according to the present invention is a cosmetic product, preferably a cosmetic product for a keratinous substance, and more preferably a cosmetic product for the care and / or revitalization of a keratinous substance. The keratinous substance here refers to a material containing keratin as its principal constituent, and examples include skin, scalp, lips, and the like. Preferably, the keratinous substance here is skin, more preferably facial skin, and even more preferably nasal skin.

[0070] In one embodiment of the present invention, the device according to the present invention is a skincare product, preferably a facial skincare product and, more preferably, a nasal skincare product. It is preferable that the device according to the present invention be used to treat or care for oily skin, for example, to treat or care for oily facial skin. (Article)

[0079] The (a) substrate may be porous or non-porous, preferably porous, meaning that the substrate includes voids or holes.

[0080] The (a) substrate can be formed by fibers such as filaments and discontinuous fibers.

[0081] In one embodiment, the (a) substrate may be selected from woven or nonwoven sheets such as woven or nonwoven fabrics. The term "nonwoven sheet" here refers to a sheet containing fibers in which individual fibers that are neither woven nor knitted are arranged in a disordered manner. Preferably, the (a) substrate may be selected from nonwoven sheets such as nonwoven fabrics.

[0082] It may be preferable for the (a) substrate to be paper.

[0083] It may be preferable for (a) the substrate to comprise at least one soluble polymer in water or dispersible in water.

[0084] The expression "water-soluble or water-dispersible polymer" here means that the polymer can dissolve or disperse in water after immersion in water at 25 °C within a period of several seconds to several days, for example, 3 days without stirring. In one embodiment, the "water-soluble or water-dispersible polymer" can dissolve or disperse upon immersion in water at 25 °C in less than a few minutes.

[0085] The water-soluble or water-dispersible polymer may be in the form of fibers.

[0086] As a water-soluble or water-dispersible polymer, a synthetic or natural water-soluble or water-dispersible polymer may be used.

[0101] As commercially available products of hydroxypropylmethylcellulose polymer (HPMC), it is possible to mention those available under the trade names METHOCEL K35, METHOCEL A15LV, METHOCEL Premium E5 LV and K35 LV from Dow Chemical Co.

[0102] The water-dispersible polymer can be chosen from among water-insoluble polymers. The expression "water-insoluble" here indicates that the polymer does not dissolve upon immersion in water at 25 °C over a period of several days, such as 3 days without stirring.

[0103] As a water-insoluble polymer, we can mention:

[0104] - water-insoluble synthetic polymers, such as polyester, the polyolefin (e.g., polypropylene and polyethylene), polyamide (e.g., nylon 6 and nylon 66), viscose, (meth)acrylics, (meth)acrylates, polyvinylidene chloride, polyurethane; and

[0105] - natural polymers insoluble in water, such as cellulose (for example, the wood pulp, cotton, hemp, jute and flax fibers), silk and keratin (such as wool fibers and camel hair fibers).

[0106] In a preferred embodiment of the present invention, the (a) substrate comprises natural fibers, in particular particular cellulosic fibers, such as wood pulp.

[0107] The (a) substrate can be produced by a conventional process such as a molding process to prepare a substrate in the form of a film, or a papermaking process to prepare a substrate in the form of paper.

[0108] As a substrate, (a) a commercially available sheet may be used. Non-limiting examples of commercially available sheets include water-soluble papers available from Nippon Paper Papylia in Japan, SmartSolve Industries in the United States, and Aquasol Cooperation in the United States, as well as fibrous materials such as PVA fiber nonwoven / woven materials available from Kuraray, etc. An example of a commercially available fiber for the substrate is a water-soluble paper marketed under the name 30MDP, available from Nippon Paper Papylia in Japan. Coating layer

[0109] The (1) item required according to the present invention comprises (b) at least one coating layer disposed on the (a) substrate. One coating layer may be disposed on one side of the (a) substrate, or two or more coating layers may be disposed on one or two sides of the (a) substrate.

[0110] It may be preferable for one or more (b) coating layers to be disposed on one side of (a) the substrate. It may be more preferable for one (b) coating layer to be disposed on one side of (a) the substrate.

[0111] The quantity of (b) coating layer(s) may be 1 g / m2 or more, preferably 3 g / m2 or more, more preferably 5 g / m2 or more, and even more preferably 10 g / m2 or more, and / or may be 200 g / m2 or less, preferably 100 g / m2 or less, more preferably 70 g / m2 or less, and even more preferably 50 g / m2 or less.

[0112] The quantity of the (b) coating layer(s) can range from 1 g / m2 to 200 g / m2, preferably from 3 g / m2 to 100 g / m2 and, more preferably, from 5 g / m2 to 70 g / m2, and even more preferably from 10 g / m2 to 50 g / m2.

[0113] The (b) coating layer comprises (bl) at least one clay and (b2) at least one water-soluble binder. In other words, the (bl) clay and the (b2) water-soluble binder are present on the (a) substrate.

[0114] The ingredients of the (b) coating layer will be described in detail below.

[0115] (b 1) Clay

[0116] The (b) coating layer comprises (bl) at least one clay. Only one type of clay may be used, but two or more different types of clay may be used in combination.

[0117] The term "clay" here refers to a natural material composed mainly of fine-grained minerals, which is generally plastic at an appropriate moisture content and hardens when dried or fired. (bl) clay occurs in the form of particles. Although clay usually contains phyllosilicates, it may contain other materials that impart plasticity and harden when dried or fired. Associated phases in clay may include materials that do not impart plasticity and organic matter. A common definition is that from the Penguin scientific dictionary, namely, "finely divided rock materials whose mineral components are various silicates, mainly magnesium or aluminum."Clay can include kaolinite (typically defined as [Si4]Al4O10(OH)8nH2O (n = 0 or 4)), illite (typically defined as Mx[Si6j8Alij2]Al3Feoj25Mgoj75O2O(OH)4), vermiculite (typically defined as Mx[Si7Al]AlFeoj5Mgo>5O2(OH)4), smectite (typically defined as Mx[Si8]Al3j2Feoj2MgOj6O2(OH)4, and chlorite (typically defined as (Al(OH) 2.55)4[Si6>8 Al1O1 >2} Al3j4Mgo,6)2O(OH)4).

[0118] Another definition, frequently used by chemists, is "a sediment or sedimentary rock of natural origin composed of one or more minerals and accessory compounds, the whole usually being rich in hydrated aluminum silicate, iron or magnesium, hydrated alumina, or iron oxide, having particles predominantly of colloidal or near-colloidal size, and commonly developing plasticity when sufficiently pulverized and wetted" (see Kirk-Othmer, Encyclopaedia of Chemical Technology, Volume 5, page 544, 2nd edition, John Wiley and Sons, Inc., New York, 1964). Examples of clays are given in the book "Clay Mineralogy," S. Caillere, S. Henin, M. Rautureau, 2nd edition 1982, Masson. Clays can be of natural or synthetic origin.

[0119] Hydrophilic clay includes smectites such as saponites, hectorites, montmorillonites, bentonites and beidellite. Hydrophilic clay includes synthetic hectorites (also called laponites) such as the products sold by BYK-Chemie under the names Laporte Laponite XLG, Laponite RD, Laponite RDS (these products are sodium silicates and magnesium silicates, in particular sodium, lithium and magnesium silicates), bentonites such as the product sold under the name Bentone® HC Rheox, magnesium silicates and aluminum-based products such as the hydrated products sold by Vanderbilt Company under the names Ultra Veegum®, Veegum® HS, Veegum® DGT, or calcium silicates, and in particular the synthetic form sold by Imerys under the name Micro-cel® C.

[0120] Fuller's earth is mainly composed of hydrated aluminum silicates which contain in their structure metallic ions such as magnesium, sodium, and calcium. Montmorillonite is the main clay mineral in fuller's earth, but other minerals such as kaolinite, attapulgite, and palygorskite, among other components, may also be included.

[0121] A lipophilic clay refers to a clay that swells in a lipophilic medium; the clay swells and forms a colloidal dispersion. Lipophilic clays include modified clays such as modified magnesium silicate (Rheox Bentone VS38 gel), hectorites modified by a C22 fatty acid ammonium chloride, such as distearyldimethylammonium ammonium chloride-modified hectorite (CTFA name: Disteardimonium hectorite) marketed as "Bentone 38 CE" by Rheox or Bentone® 38V by ELEMENTIS.

[0122] The origin of such a clay may be a natural or synthetic mineral clay, such as hectorite, bentonite and their quaternized derivatives, for example obtained by reacting the minerals with a quaternary ammonium compound, such as stearalkonium bentonite, hectorites, quaternized hectorites such as Quatemium-18 hectorite, carbonates such as propylene carbonate, bentones, and the like.

[0123] Non-limiting examples of (bl) clay that can be used in the present invention are fuller's earth, volcanic ash mud from Pinatubo, Philippines, Aleppo clay from Syria, volcanic mud from Pulau Tiga, Malaysia, mud from Nha Trang, Vietnam, white kaolinite from Korea, yellow loess from Korea, volcanic clay from Jeju, Korea, mud from Guanziling, Taiwan, volcanic mud from Wudalianchi, China, black mud from Yuncheng Salt Lake, China, mineral mud from Tantou Village, China, Chinese clay (kaolin), Maifan stone from China, clay from Beppu Onsen Fango, Japan, Kucha clay, Japan, Tanakura clay, Japan; Cambrian blue clay from Russia; Blue Lagoon mud from Iceland; Saki Lake mud from Ukraine; Karlovy Vary peat mud, Czech Republic; Heviz Georgikon peat mud, Hungary; Austrian Alps peat mud; Bad Wilsnack mud, Germany; Bavarian mountain salt mineral mud, Germany; Freiburg volcanic mud, Germany; Santorini mud, Greece; Mar Menor mud, Spain; Ischia volcanic mud, Italy; Euganean thermal mud, Italy; yellow illite clay from France; French green clay - Montmorillonite; Calistoga mud, USA; Sacred clay and Formalite from the USA; Redmond clay, USA; Arctic mineral mud from Canada; Tulum Mayan clay, Mexico; Canadian glacial clay; white clay Amazonian mud from Brazil, volcanic thermal mud from El Chillante, Argentina, African medicinal clay and Australian olive green clay.

[0124] Advantageously, the (bl) clay is chosen from the group consisting of kaolin, hectorites, montmorillonites, bentonites and one of their mixtures.

[0125] The content of the clay(s) in the coating layer(s) may be 50% by weight or more, preferably 60% by weight or more, more preferably 70% by weight or more, and even more preferably 80% by weight or more, and / or may generally be 99% by weight or less, preferably 98% by weight or less, more preferably 97% by weight or less, and even more preferably 96% by weight or less, relative to the total weight of the coating layer(s). All combinations of the upper and lower limit values ​​are available.

[0126] Therefore, the (b) coating layer(s) may comprise the (bl) clay(s) in an amount from 50% to 99% by weight, preferably from 60% to 98% by weight, more preferably from 70% to 97% by weight, and even more preferably from 80% to 96% by weight, relative to the total weight of the (b) coating layer(s).

[0127] (b2) Water-soluble binder

[0128] The (b) coating layer comprises (b2) at least one water-soluble binder. Only one type of water-soluble binder may be used, but two or more different types of water-soluble binders may be used in combination.

[0129] The (b2) water-soluble binder can function to bind or adhere particles of the (bl) clay in the coating layer, and / or bind or adhere particles of the (bl) clay to the (a) substrate.

[0130] In a preferred embodiment, the (b2) water-soluble binder comprises at least one polar polymer. In another preferred embodiment, the (b2) water-soluble binder is selected from water-soluble film-forming polymers. As for the water-soluble film-forming polymer used in the present invention, it is possible to mention:

[0131] - polysaccharides, including starches, pullulans, cellulose derivatives and their combinations;

[0132] - proteins, such as plant-based proteins, such as proteins of wheat or soy; animal-derived proteins, such as keratins, for example keratin hydrolysates and sulfonic keratins;

[0133] - (meth)acrylic polymers or copolymers, such as polyacrylates or polymethacrylates;

[0134] - vinyl polymers, such as polyvinylpyrrolidones, copolymers methyl vinyl ether and malic anhydride, vinyl acetate and crotonic acid copolymer, vinylpyrrolidone and vinyl acetate copolymers, vinylpyrrolidone and caprolactam copolymers, or polyvinyl alcohol;

[0135] - anionic, cationic, amphoteric or non-ionic polymers of chitin or chitosan;

[0136] - arabic gums, guar gum, xanthan compounds or gum of Karaya;

[0137] - alginates and carrageenans;

[0138] - glycosaminoglycans, hyaluronic acid and its compounds;

[0139] - shellac resin, sandarac gum, dammars, elemis or copals;

[0140] - a deoxyribonucleic acid;

[0141] - mucopolysaccharides, such as chondroitin sulfates and

[0142] - their mixtures.

[0143] Advantageously, the water-soluble film-forming polymer is selected from the group consisting of starch, pullulan, cellulose, their derivatives, polyvinyl alcohol, polyvinylpyrrolidone, and one of their mixtures.

[0144] The (b2) water-soluble binder may be identical or different from the water-soluble polymer for the (a) substrate. These materials can be distinguished from one another by consideration of their functions and / or states. Specifically, the water-soluble polymer, if present, in the (a) substrate forms the substrate; that is, this polymer is part of the substrate, while the (b2) water-soluble binder serves to make the (b1) clay adhere to the substrate. A person skilled in the art can easily distinguish them by analyzing the requirements of the present invention. For example, the (b2) water-soluble binder is in direct contact with the (b1) clay and may be present on the surface of the (b1) clay. On the other hand, the water-soluble polymer in the (a) substrate is positioned within the substrate.

[0145] In one embodiment of the present invention, the (b2) water-soluble binder is different from the water-soluble polymer, if present, forming the (a) substrate.

[0146] The content of (b2) water-soluble binder(s) in the (b) coating layer(s) may be 0.1% by weight or more, preferably 0.5% by weight or more, more preferably 1% by weight or more, and even more preferably 2% by weight or more, and / or may generally be 15% by weight or less, preferably 10% by weight or less, more preferably 7% by weight or less, and even more preferably 5% by weight or less, relative to the total weight of the (b) coating layer(s). All combinations of the upper and lower limit values ​​are available.

[0147] Therefore, the (b) coating layer(s) may comprise the (b2) water-soluble binder(s) in an amount from 0.1% to 15% by weight, preferably from 0.5% to 10% by weight, more preferably from 1% to 7% by weight, and even more preferably from 2% to 5% by weight, relative to the total weight of the (b) coating layer(s).

[0148] (b3) Optional ingredient

[0149] The coating layer(s) may include at least one optional ingredient other than (bl) clay and (b2) water-soluble binder.

[0150] - Cosmetically active ingredient

[0151] The (b) coating layer may comprise at least one cosmetically active ingredient. Only one type of cosmetically active ingredient may be used, but two or more different types of cosmetically active ingredients may be used in combination.

[0371] The present invention also relates to a cosmetic process for the skin, preferably a cosmetic process for facial skin and, more preferably, for the skin of the nose. The cosmetic process according to the present invention is a non-therapeutic process for beautifying the appearance of the skin, preferably facial skin, and more preferably nasal skin.

[0372] The cosmetic process according to the present invention comprises the following steps: 1. application to the skin (2) of at least one composition comprising

[0373] (i) at least one cationic polymer, preferably as defined above and

[0374] (ii) at least one non-ionic polymer, preferably as defined above; 1. application to the skin after step (1) of at least one article comprising

[0375] (a) at least one substrate, preferably as defined above and

[0376] (b) at least one coating layer disposed on the substrate, comprising (bl) at less a clay, preferably as defined above and (b2) at least a water-soluble binder, preferably as defined above; 1. keeping the (1) article on the skin; and 2. Removal of the (1) article from the skin.

[0377] The cosmetic process according to the present invention can control sebum on the skin and eliminate skin comedones with reduced pain and / or reduced skin damage.

[0378] The cosmetic process according to the present invention can reduce the amount of sebum on the skin and / or delay the increase in the amount of sebum on the skin over time.

[0379] The cosmetic process according to the present invention can also eliminate comedones, such as blackheads and closed comedones, from the pores of the skin.

[0380] Step (1) is an application step of the composition (2), as explained above, to the skin. The means of applying the composition (2) to the skin are not not limited. For example, one or more of a user's fingers may be used to apply the (2) composition to the skin.

[0381] In one embodiment of the present invention, the skin can be cleaned with water, if necessary, before step (1).

[0382] Step (2) is an application step of the (1) article, as explained above, to the skin which has been treated with the (2) composition in step (1). This step can be carried out, for example, by placing the (1) article on the skin which has been treated with the (2) composition in step (1).

[0383] Step (3) is a step which consists of leaving the (1) article applied to the skin by step (2) for a certain period of time in order to make the skin neither wet nor dry. This step can be carried out by waiting a sufficient period of time, called the "application time", after placing the (1) article in contact with the skin, until the (1) article absorbs the (2) composition to make the skin neither wet nor dry.

[0384] The application time of step (3) can range from 1 minute to 30 minutes, preferably from 3 minutes to 25 minutes, more preferably from 5 minutes to 20 minutes, and even more preferably from 10 minutes to 15 minutes. Step (3) can be carried out at room temperature (25 °C) and atmospheric pressure (105 Pa).

[0385] In step (3), the (1) article can absorb any sebum, excess oil, and impurities from the skin. Therefore, the process according to the present invention can control sebum on the skin.

[0386] Step (4) is a step of removing the (1) article from the skin, as explained above. In step (4), the comedones on the skin can be removed because the comedones adhere to the (1) article, and the (1) article with the comedones is removed from the skin. Thus, the comedones in the pores of the skin can be eliminated by the cosmetic process according to the present invention.

[0387] The force required to remove the (1) article from the skin is not as high as that of conventional cosmetic products intended for removing comedones. The method for measuring the force is described in detail in the following Examples section. The force can be from 0.5 to 9 N / 2cm, preferably from 0.6 to 5 N / 2cm, and more preferably from 0.7 to 2 N / 2cm. Therefore, the process according to the present invention can remove comedones from the skin with reduced pain and / or reduced skin damage.

[0388] The cosmetic process according to the present invention may further include the step of (5) cleansing the skin in order to remove from the skin residues of (1) article.

[0389] If the (a) substrate of the (1) article is soluble in water or dispersible in water, the residue of the (1) article can be easily removed from the skin, for example by rubbing the skin or washing the skin with the hands, using water. EXAMPLES

[0390] The present invention will be described in more detail by means of examples. However, these examples shall not be construed as limiting the scope of the present invention. Article preparation

[0391] An article used for the necessary and cosmetic process according to the present invention has been prepared as follows.

[0392] A coating composition was prepared by mixing the ingredients shown in Table 1. The numerical values ​​for the quantities of the ingredients are all based on the "% by weight" as raw materials.

[0393] [Table 1] Table 1 Ingredient % by weight: Kaolin (clay) 90.5, Polyvinylpyrrolidone 1.9, Ethanol 7.3, Chromium oxide green 0.3

[0394] The coating composition thus prepared was dispersed in isopropyl alcohol, then coated onto 30MDP water-soluble paper (0.065 mm thick) from Nippon Paper Papylia with a coating bar to prepare a coated paper. The coated paper was dried at 70 °C to obtain the article. The clay content was 14 g / m². The resulting article was cut into the shape of a face mask, as illustrated in [Fig. 1]. Examples 1 to 3 and Comparative Examples 1 to 3 [Preparation]

[0395] Each of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 3 was prepared by mixing the ingredients shown in Table 2. The numerical values ​​for the quantities of the ingredients are all based on the "% by weight" as raw materials.

[0396] [Table 2] Table 2 Ex. 1 Ex. 2 Ex. 3 Ex. com P- 1 Ex. com p. 2 Ex. com p. 3 Water qs 100 qs 100 qs 100 qs 100 qs 100 qs 100 Chitosan 2.0 2.2 2.2 2.0 - - Lactic acid 1.0 1.3 1.3 1.0 - - Phenoxyethanol 0.5 0.5 0.5 0.5 0.5 0.5 Hydroxyethylcellulose 0.5 0.5 - - 0.5 - Pullulan - - 2.0 - - 1.0 [Assessment]

[0397] (Tear-out force test)

[0398] Each of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 3, in a quantity of 39.5 mL, was applied to a rectangular glass slide, Micro slide glass SI 112, from Matsunami Glass Ind. Ltd. Next, the article prepared as described above was cut into rectangular shapes (width: 2 cm) and placed on the rectangular glass slide so that the clay-coated surface of the sample article faced the composition spread on the glass slide, and one edge of the sample article was positioned on the edge of the glass slide to form a free end. The sample article was left for 15 minutes until the composition was completely absorbed by the sample article.

[0399] As a device for measuring the pull-out force, a combination of a ZTS-50N dynamometer and an MX2-500N base supplied by IMADA Co., Ltd. in Japan was used.

[0400] The glass plate was fixed to the MX2-500N base, and the free end of the sample article was pinched and gripped by a pinch of the ZTS-50N dynamometer. The pinched free end of the sample article was moved upwards at a 90° angle to pull the sample article from the glass plate. The dynamometer reading was recorded as the pull-off force (N / 2 cm). The results are shown in Table 3.

[0401] [Table 3] Table 3 Ex. 1 Ex. 2 Ex. 3 Ex. com P- 1 Ex. com p. 2 Ex. com p. 3 Ref. 1 Age tear force (N / 2cm) 0.99 0.79 1.01 0.12 0.09 0.08 >9.70

[0402] The value of "Ref. 1" in Table 3 is the pull-out force measured in the same manner as described above (provided that water is used instead of the composition according to Examples 1 to 3 and Comparative Examples 1 to 3) for a commercial product, purchased in June 2023, marketed by KAO as KAO Men's Biore Pore pack, in the form of a sheet for removing blackheads on a nose.

[0403] (Blackhead Removal Capacity Test)

[0404] Each of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 3 was applied to the skin of a panelist's nose, and then the article in the form of [Fig. 1] was applied to the skin. After 15 minutes, the article was removed from the skin.

[0405] The ability to remove blackheads was evaluated by comparing images of the nose with Canfield Scientific's VISIA-CR™ before and after the above treatment.

[0406] The same test was carried out using the commercial product used for the "Pulling Force Test" above, purchased in June 2023, marketed by KAO under the name KAO Men's Biore Pore pack, as a reference, provided that water was used instead of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 3.

[0407] It was found that the use of the compositions according to Examples 1 to 3 gave the same level of blackhead removal as the control.

[0408] On the other hand, the use of the compositions according to Comparative Examples 1 to 3 could not provide a good adaptation of the article to the skin and could not eliminate blackheads.

[0409] (Skin lesion test)

[0410] The composition according to example 1 was applied to the skin of the nose of 20 female panelists, then the article in the form of [Fig. 1] was applied to the skin. After 15 minutes, the article was peeled off the skin.

[0411] Immediately after the above treatment, transepidermal water loss (TEWL), which is an essential parameter for evaluating the skin's water barrier function, was assessed with the Tewameter® TM HEX from Courage+Kazaka, Germany.

[0412] The same test was carried out using as a control the commercial product used for the "Pull-out force test" above (Ref. 1).

[0413] The results are presented in Table 4.

[0414] [Table 4] Table 4 Ex. 1 Ref. 1 TEWL imm -1.3 -1.6

[0415] The lower the TEWL values, the more water evaporates from the skin. Thus, a decrease in TEWL values ​​reflects more skin damage (due to the deterioration of the skin barrier function).

[0416] (Serum control test)

[0417] The composition according to Example 1 was applied to the skin of the forehead of 20 female panelists, then the article in the form of [Fig. 1] was applied to the skin. After 15 minutes, the article was peeled off the skin.

[0418] The amounts of sebum on the skin immediately after the above treatment, as well as 2 hours and 4 hours later, were measured using the Sebumeter SM815MP from Courage+Kazaka, Germany. The results are shown in Table 5.

[0419] [Table 5] Table 5 Ex. 1 Ref. 2 Timm -69 -43 T 2hs -49 -15 T4hs -20 1.8

[0420] The value of "Ref. 2" in Table 5 corresponds to the quantity of sebum measured in the same way, provided that a non-woven facial mask, made of polyolefin fibres which had been impregnated with the composition including the ingredients indicated in Table 6, had been applied to the skin.

[0421] [Table 6] Table 6 Ingredients % by weight: Water q.s. 100, Glycerin 8.0, Propanediol 5.0, Kaolin 6.0

[0422] The lower the value, the more the amount of sebum is reduced.

[0423] (Summary)

[0424] By using the compositions according to Examples 1 to 3, the article can be torn off more easily compared to the conventional product available on the market (Ref. 1), while offering a good blackhead removal capacity which is as good as that of the conventional product available on the market (Ref. 1).

[0425] Furthermore, it can be understood that by using the necessary cosmetic process according to the present invention, skin damage can be reduced, and sebum on the skin can be suppressed for a long period of time.

[0426] On the other hand, using the compositions according to Comparative Examples 1 to 3, the article was unable to eliminate blackheads from the skin.
