Description

[Technical Field]

[0001] The present invention relates to a kit and a cosmetic method useful for skin care. [Background technology]

[0002] Oily skin is caused by excessive secretion of oily / waxy substances from sebaceous glands. Sebaceous glands are distributed throughout all skin areas except the palms and soles, but they are most abundant on the face and scalp. Sebum contains triglycerides, wax, squalene, and metabolites of adipocytes. Sebum maintains the flexibility of hair and skin, but excessive sebum can contribute to the concentration of keratinocytes at the opening of sebaceous follicles on the surface of the skin, which causes contraction at the follicular opening and leads to keratinocyte plugs. This can result in blackheads, whiteheads, significant irritation, redness, tissue damage, and acne. In this specification, comedones refer to both whiteheads and blackheads.

[0003] There are many commercially available products aimed at controlling sebum and comedones on the skin.

[0004] The use of mineral clay as a medicinal and cosmetic tool for sebum control has long been popular in the marketplace. Clays are used to absorb excess oil or sebum, dirt, and toxins from the skin while simultaneously exfoliating and improving circulation in the skin.

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

[0006] WO 2024 / 034324 describes a sheet-form 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 containing water-soluble polymers such as polyvinyl alcohol for removing keratin plugs from pores on the skin have also been popular on the market for a long time.These conventional pore cleansing strips or packs are useful for removing comedones from the skin.

[0008] However, conventional pore cleansing strips or packs require a lot of force to remove from the skin and therefore tend to cause pain and / or skin damage when removed from the skin. [Prior art documents] [Patent documents]

[0065] The (b) coating layer comprises (b1) at least one clay and (b2) at least one water-soluble binder. In other words, the (b1) clay and the (b2) water-soluble binder are present on the (a) substrate.

[0066] (b) The components in the coating layer are described in detail below.

[0067] (b1) Clay The coating layer (b) contains (b1) at least one type of clay. A single type of clay may be used, or two or more different types of clay may be used in combination.

[0068] The term "clay" as used herein refers to a naturally occurring material composed primarily of fine-grained minerals, which is generally plastic with the appropriate amount of moisture and hardens when dried or fired. (b1) Clay is in the form of particles. Clays usually contain phyllosilicates but may also contain other materials that impart plasticity and harden when dried or fired. Associated phases in clays may include materials that do not impart plasticity and organic matter. A common definition is that given in the Penguin Dictionary of Science: "a finely divided rock material whose constituent minerals are various silicates, mainly of magnesium or aluminum origin." Clays are composed of kaolinite (typically [Si4]Al4O 10 (OH)8.nH2O (n=0 or 4)), illite (typically M x [Si 6.8 Al 1.2 ]Al3Fe 0.025 Mg 0.75 O 20 (OH)4), vermiculite (typically M x [Si7Al]AlFe 0.05 Mg0.5 O2(OH)4), smectite (typically M x [Si8]Al 3.2 Fe 0.2 Mg 0.6 O2(OH)4), and chlorite (typically (Al(OH) 2.55 )4[Si 6.8 AlO 1.2 ]Al 3.4 Mg 0.6 ) 20 (OH)4).

[0069] Another definition frequently used by chemists is "a naturally occurring deposit or sedimentary rock, composed of one or more minerals and accessory compounds, the bulk of which is usually rich in hydrated aluminum silicate, iron or magnesium, hydrated alumina, or iron oxide, consisting primarily of particles of colloidal or near-colloidal size, and which, when thoroughly crushed and moistened, usually exhibits plastic properties" (see Kirk-Othmer, Encyclopaedia of Chemical Technology, Vol. 5, p. 544, 2nd ed., John Wiley and Sons, Inc., New York, New York 1964). Examples of clays are found in the book "Clay mineralogy, S. Caillere, S. Henin, M. Rautureau, 2nd ed., 1982, Masson." Clays may be of natural or synthetic origin.

[0070] Hydrophilic clays include smectites such as saponite, hectorite, montmorillonite, bentonite, beidellite.Hydrophilic clays include synthetic hectorites (also called Laponites), such as the products sold by BYK-Chemie under the names Laporte Laponite XLG, Laponite RD, and Laponite RDS (these products are sodium and magnesium silicates, especially sodium, lithium, and magnesium), bentonites such as the products sold under the name Bentone® HC Rheox, magnesium silicate and aluminum products such as the hydrated magnesium silicates sold by Vanderbilt Company under the names Ultra Veegum®, Veegum® HS, and Veegum® DGT, or calcium silicates, especially synthetic forms, such as those sold by Imerys under the name Micro-cel® C.

[0071] Fuller's earth consists primarily of hydrated aluminum silicates that contain metal ions such as magnesium, sodium, and calcium within their structure. Montmorillonite is the primary clay mineral in Fuller's earth, but other minerals such as kaolinite, attapulgite, and palygorskite, among other components, may also be included.

[0072] Organophilic clays are clays that swell in an oleophilic medium, forming a colloidal dispersion. Organophilic clays include those containing ammonium chlorides of fatty acids C, such as hectorite modified with ammonium distearyldimethylammonium chloride (CTFA name: disteardimonium hectorite), sold under the name "Bentone 38 CE" by Rheox or under the name Bentone® 38V by ELEMENTIS. 10 ~C 22 Examples of modified clays include modified magnesium silicate (Bentone gel VS38 from Rheox) and hectorite.

[0073] The source of such clays can be natural or synthetic mineral clays such as hectorite, bentonite, and their quaternized derivatives, for example obtained by reacting minerals with quaternary ammonium compounds, e.g., stearalkonium bentonite, hectorite, quaternized hectorites such as quaternium-18 hectorite, carbonates such as propylene carbonate, bentones, etc.

[0074] Non-limiting examples of (b1) clay that can be used in the present invention include Fuller's earth, Pinatubo volcanic ash mud from the Philippines, Aleppo clay from Syria, Tiga Island volcanic mud from Malaysia, Nha Trang mud from Vietnam, white kaolinite from Korea, Korean loess, Jeju volcanic clay from Korea, Kwanzi Ling mud from Taiwan, Wudalianchi volcanic mud from China, black mud from Yuncheng Salt Lake in China, mineral mud from Tanto Village in China, china clay (kaolin), Maifan stone from China, Beppu Onsen Fango from Japan, Kucha from Japan, Tanaka clay from Japan, Cambrian blue clay from Russia, Blue Lagoon mud from Iceland, Saki Lake mud from Ukraine, Karlovy Vary Marsh mud from the Czech Republic, Hévíz Georgíkon from Hungary, and the like.

[0075] Advantageously, (b1) the clay is selected from the group consisting of kaolin, hectorite, montmorillonite, bentonite, and mixtures thereof.

[0076] The content of (b1) clay in the (b) coating layer may be 50% by mass or more, preferably 60% by mass or more, more preferably 70% by mass or more, even more preferably 80% by mass or more, and / or generally 99% by mass or less, preferably 98% by mass or less, more preferably 97% by mass or less, even more preferably 96% by mass or less, based on the total mass of the (b) coating layer. Any combination of upper and lower limits may be used.

[0077] Therefore, the (b) coating layer may contain (b1) clay in an amount ranging from 50% to 99% by mass, preferably from 60% to 98% by mass, more preferably from 70% to 97% by mass, and even more preferably from 80% to 96% by mass, based on the total mass of the (b) coating layer.

[0078] (b2) Water-soluble binder The coating layer (b) contains at least one water-soluble binder (b2). A single type of water-soluble binder may be used, or two or more different types of water-soluble binders may be used in combination.

[0079] The (b2) water-soluble binder can function to bind or adhere the (b1) clay particles in the coating layer and / or to bind or adhere the (b1) clay particles to the (a) substrate.

[0080] In a preferred embodiment, (b2) the water-soluble binder comprises at least one polar polymer.

[0082] The (b2) water-soluble binder may be the same as or different from the water-soluble polymer for the (a) substrate. These materials can be distinguished from each other in view of their function and / or state. Specifically, the water-soluble polymer in the (a) substrate, if present, forms the substrate, i.e., this polymer is part of the substrate, while the (b2) water-soluble binder acts to adhere the (b1) clay to the substrate. Those skilled in the art can easily distinguish between them by analyzing the kit of the present invention. For example, the (b2) water-soluble binder can be in direct contact with the (b1) clay and present on the surface of the (b1) clay. On the other hand, the water-soluble polymer in the (a) substrate is located in the substrate.

[0083] In one embodiment of the present invention, (b2) the water-soluble binder is different from the (a) water-soluble polymer (if present) that forms the substrate.

This step can be carried out by placing the (1) article in contact with the skin and then waiting a period of time called the "application time" sufficient for the (1) article to absorb the (2) composition and bring the skin to a dry or non-wet state.

[0253] The application time in step (3) may be in the range of 1 minute to 30 minutes, preferably 3 minutes to 25 minutes, more preferably 5 minutes to 20 minutes, and even more preferably 10 minutes to 15 minutes. Step (3) is carried out at room temperature (25°C) and atmospheric pressure (10 5 Pa).

[0254] In step (3), the (1) article can absorb sebum, excess oil, and impurities from the skin, and therefore the method according to the present invention can control sebum on the skin.

[0255] Step (4) is a step of peeling the (1) article from the skin as described above. In step (4), the comedones on the skin become adhered to the (1) article, and the (1) article with the comedones attached thereto is removed from the skin, thereby removing the comedones on the skin. Therefore, the comedones in the pores of the skin can be removed by the cosmetic method according to the present invention.

[0256] The force required to peel the (1) article from the skin is not as strong as that required for conventional beauty products for removing comedones. A method for measuring the force is described in detail in the Examples section below. The force may be 0.5 to 9 N / 2 cm, preferably 0.6 to 5 N / 2 cm, and more preferably 0.7 to 2 N / 2 cm. Therefore, the method according to the present invention can remove comedones from the skin with less pain and / or reduced skin damage.

[0257] The cosmetic method according to the present invention may further comprise the step (5) of (1) cleansing the skin to remove any remaining parts of the article from the skin.

[0258] If the (a) substrate of the (1) article is water-soluble or water-dispersible, the remainder of the (1) article can be easily removed from the skin, for example, by rubbing the skin with hands or washing the skin with water. [Example]

[0259] The present invention will now be described in more detail by way of examples, which should not be construed as limiting the scope of the present invention.

[0260] Preparation of the article The products used in the kit and cosmetic method according to the present invention were prepared as follows.

[0261] Coating compositions were prepared by mixing the components shown in Table 1. All component amounts are based on "mass %" of the ingredients.

[0262] [Table 1]

[0263] The coating composition thus prepared was dispersed in isopropyl alcohol and then coated onto a water-soluble paper 30MDP (thickness: 0.065 mm) manufactured by Nippon Paper Papylia Co., Ltd. by the bar coating method to prepare coated paper. The coated paper was dried at 70°C to obtain an article. The amount of clay was 14 g / m 2 The resulting article was cut into the shape of a facial mask as shown in FIG.

[0264] (Examples 1 to 3 and Comparative Examples 1 to 3) [Preparation] Each of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 3 was prepared by mixing the components shown in Table 2. The numerical values ​​for the amounts of the components are all based on "mass %" of the raw materials.

[0265] [Table 2]

[0266] [evaluation] (peel force test) A 39.5 mL amount of each composition according to Examples 1 to 3 and Comparative Examples 1 to 3 was applied onto a rectangular glass plate (microscope slide S1112, Matsunami Glass Industry Co., Ltd.). The prepared article was then cut into a rectangular shape (width: 2 cm) and placed on the rectangular glass plate, with the clay-coated surface of the sample article facing the composition spread on the glass plate and one edge of the sample article positioned beyond the edge of the glass plate to become a free edge. The sample article was left for 15 minutes until the composition was completely absorbed into the sample article.

[0267] The device used to measure the peel force was a combination of a ZTS-50N force gauge and a MX2-500N base supplied by Imada Co., Ltd., Japan.

[0268] The glass plate was fixed on the base of the MX2-500N, and the free end of the sample was clamped and lifted using the force gauge of the ZTS-50N. The clamped free end of the sample was moved upward at a 90° angle, and the sample part was peeled off from the glass plate. The force gauge value was recorded as the peel force (N / 2 cm). The results are shown in Table 3.

[0269] [Table 3]

[0270] The value for "Reference Example 1" in Table 3 is the peeling force measured in the same manner as above (except that water was used instead of the compositions of Examples 1 to 3 and Comparative Examples 1 to 3) for a commercially available product in sheet form for removing blackheads from the nose, sold by Kao Corporation under the name Kao Men's Biore Pore Pack (purchased in June 2023).

[0271] (Blackhead removal rate test) Each of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 3 was applied to the nasal skin of a panelist, and then the article having the form shown in Figure 1 was applied to the skin. After 15 minutes, the article was removed from the skin.

[0272] Blackhead removal rate was assessed by comparing nasal images taken before and after the above treatments using a VISIA-CR™ from Canfield Scientific.

[0273] The same test was carried out using as a reference a commercially available product sold by Kao Corporation under the name Kao Men's Biore Pore Pack (purchased in June 2023), which was used in the above "peeling force test." However, water was used instead of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 3.

[0274] It was found that use of the compositions according to Examples 1-3 achieved the same level of blackhead removal as the reference.

[0275] On the other hand, the use of the compositions according to Comparative Examples 1 to 3 did not allow the article to fit snugly onto the skin and did not remove blackheads.

[0276] (Skin damage test) The composition according to Example 1 was applied to the nasal skin of 20 female panelists, and then the article in the form of Figure 1 was applied to the skin. After 15 minutes, the article was removed from the skin.

[0277] Immediately after the treatment, transepidermal water loss (TEWL), an essential parameter for evaluating the water barrier function of the skin, was evaluated by Tewameter®™ HEX manufactured by Courage+Kazaka, Germany.

[0278] The same test was carried out using the commercial product used in the "Peel Force Test" above as a reference (Reference Example 1).

[0279] The results are shown in Table 4.

[0280] [Table 4]

[0281] The lower the TEWL value, the more water evaporates from the skin, so a decrease in TEWL value reflects greater skin damage (due to a deterioration of the skin's barrier function).

[0282] (Sebum control test) The composition according to Example 1 was applied to the skin on the forehead of 20 female panelists, and then the article in the form of Figure 1 was applied to the skin. After 15 minutes, the article was removed from the skin.

[0283] The amount of sebum on the skin was measured immediately after the treatment and 2 and 4 hours later using a Sebumeter SM815MP manufactured by Courage+Kazaka, Germany. The results are shown in Table 5.

[0284] [Table 5]

[0285] The "Reference Example 2" value in Table 5 is the amount of sebum measured in the same manner, except that a nonwoven face mask made of polyolefin fibers impregnated with a composition containing the ingredients shown in Table 6 was applied to the skin.

[0286] [Table 6]

[0287] The lower the value, the greater the reduction in sebum volume.

[0288] (Summary) By using the compositions according to Examples 1 to 3, the articles can be peeled off more easily compared to the conventional commercially available product (Reference Example 1), and at the same time, can provide a blackhead removal rate as good as that of the conventional commercially available product (Reference Example 1).

[0289] In addition, it can be seen that by using the kit or cosmetic method according to the present invention, skin damage can be reduced and sebum on the skin can be suppressed for a long period of time.

[0290] On the other hand, by using the compositions according to Comparative Examples 1 to 3, the articles were unable to remove blackheads from the skin.
