[0046] Furthermore, when the material for the woven or nonwoven fabric is pulp, it is preferable to use layers of thin pulp to achieve both softness and strength. Pulp reinforced with thermoplastic resin is preferable because it can be given an appropriate thickness (bulkiness) by embossing and does not wet the skin too much. In addition, by partially bonding multiple sheets together by heat sealing, a soft, thick sheet with a good wiping feel can be provided, resulting in a better user experience.

[0047] The average basis weight of the woven or nonwoven fabric is preferably 20 g / m², from the viewpoint of good retention of the liquid composition and a good feel when wiping. 2 The above is more than 30 g / m 2 More preferably 40 g / m² 2 That's all. From a similar viewpoint, the average basis weight of the woven or nonwoven fabric is preferably 150 g / m². 2 The following, and more preferably 100 g / m² 2 The following applies. Furthermore, from the viewpoint of improving the transferability of the composition to the skin, the average basis weight of the woven or nonwoven fabric is preferably 70 g / m². 2 The following is more preferable: 50 g / m 2 The following applies: The average basis weight is determined in accordance with JIS L 1913, by cutting a nonwoven fabric to a certain size and measuring its mass (g), and then calculating the average basis weight per square meter. 2It can be calculated by converting it to its mass.

[0048] The thickness of the woven or nonwoven fabric is preferably 0.15 mm or more, and more preferably 0.30 mm or more, from the viewpoint of improving the retention of the liquid composition and providing a good user experience when wiping. From a similar viewpoint, the thickness of the woven or nonwoven fabric is preferably 1.30 mm or less, and more preferably 0.90 mm or less. Here, the thickness of the woven or nonwoven fabric is 20 gf / cm² under pressure. 2 This is obtained by measuring the load using a dial gauge.

From the above perspective, the shape of the woven or nonwoven fabric is specifically sheet-like. Furthermore, the planar shape of the woven or nonwoven fabric can be, for example, rectangular. The length of one side of the rectangle is, for example, about 3 to 30 cm, preferably about 5 to 20 cm.

[0050] Next, we will explain the manufacturing method for sheet-type cosmetic products. A method for producing a sheet-like cosmetic includes, for example, the steps of preparing a liquid composition and a woven or nonwoven fabric to be used as a sheet base, and impregnating the woven or nonwoven fabric with the liquid composition. In the process of impregnating with a liquid composition, there are no restrictions on the impregnation method. For example, methods include spraying the liquid composition onto the sheet substrate using a spray or air gun, or directly applying the liquid composition to the sheet substrate using a slit-type nozzle.

[0051] From the viewpoint of the refreshing feeling after wiping, the impregnation rate of the liquid composition is preferably 180% by mass or more, more preferably 200% by mass or more, and even more preferably 230% by mass or more, relative to the mass of the woven or nonwoven fabric. Furthermore, from the viewpoint of quick drying after wiping, the impregnation rate of the liquid composition is preferably 550% by mass or less, more preferably 500% by mass or less, even more preferably 470% by mass or less, and even more preferably 450% by mass or less, relative to the mass of the woven or nonwoven fabric.

[0052] The sheet-like cosmetic obtained in this embodiment can be suitably used, for example, as a sheet-like cleaning material.

[0053] Furthermore, the sheet-type cosmetic obtained in this embodiment may be applied to bare skin, for example, or it may be used in a skincare method that includes a step of wiping skin with makeup applied using the sheet-type cosmetic.

[0054] (packaging) In this embodiment, the packaging is, for example, a packaging material containing the sheet-like cosmetic in this embodiment, and is preferably sealed. There are no restrictions on the materials used for the packaging. For example, a laminated film can be made by sandwiching a barrier layer such as an aluminum sheet (aluminum foil) or a silica vapor-deposited film between layers, and covering both sides of this barrier with synthetic resin film layers made of materials such as polyethylene, polyethylene terephthalate, polypropylene, polyester, polyamide, or polyvinyl chloride. Furthermore, there are no restrictions on the shape of the packaging; for example, it can be a pillow bag, gusseted bag, pouch, box, bottle, jar, etc. A single package may contain one sheet of cosmetic material, or two or more sheets of cosmetic material. Alternatively, two or more sheets of cosmetic material may be connected together within a single package. In this case, for example, the nonwoven fabric may have perforations, allowing the user to cut off the desired amount of cosmetic material along the perforations. Sheet-type cosmetics are stored, for example, in a folded or rolled state.

[0057] The embodiments of the present invention have been described above, but these are merely examples, and various other configurations can also be adopted. [Examples]

[0058] (Examples 1-31, Comparative Examples 1 and 2) Liquid compositions for each example were prepared using the formulations shown in Tables 1 to 6 by the following method, and these were impregnated into nonwoven fabrics to obtain sheet-like cosmetic materials for each example. In Tables 1 to 6, the amounts of each component are expressed as active amounts (unit: mass%).

[0059] (Method for preparing a liquid composition) Each component was added to the aqueous phase to prepare the liquid composition for each example.

[0060] (Method for manufacturing sheet-type cosmetic) The liquid compositions obtained in each example were evenly impregnated into the nonwoven fabric, and then the liquid was spread to ensure uniform impregnation. The impregnation rate of the liquid composition was 300% by mass in all examples except Examples 16, 17, and 28-31 (Tables 1-5), and 350% by mass in Examples 16 and 17 (Table 6). In Examples 28-31 (Table 6), the impregnation rates were 200% by mass, 250% by mass, 400% by mass, and 450% by mass, respectively. The nonwoven fabrics used in each example are as follows: Examples 1-11, 14-17, 19-31, Comparative Example 1, Comparative Example 2 (Tables 1, 2, 4-6): Nonwoven fabric 1 (AS-40, manufactured by Yamato Spinning Co., Ltd., rayon / PP·PE=80 / 20, 9cm x 12cm, average thickness 0.45±0.04mm, average basis weight 40g / m²) 2 ) Example 12 (Table 3): Nonwoven fabric 2 (Cotace C045R / A02, manufactured by Unitika, 100% cotton, 9cm x 12cm, average thickness 0.35±0.08mm, average basis weight 45g / m²) 2 ) Example 13 (Table 3): Nonwoven fabric 3 (Escot CO60P / A01, manufactured by Unitika, cotton / PET / PE=50 / 31 / 19, 9cm x 12cm, average thickness 0.48±0.07mm, average basis weight 60g / m²) 2 ) Example 18 (Table 1): Nonwoven fabric 4 (PT-50, manufactured by Yamato Spinning Co., Ltd., rayon / PP·PE=80 / 20, 9cm x 12cm, thickness 0.36mm, average basis weight 50g / m²) 2 )

[0061] (Evaluation method) For each sheet-type cosmetic obtained in the examples listed in Tables 1 to 6, the liquid retention of the sheet, the transferability of powders in the cosmetic to the skin, the effect of removing stickiness from the skin, the duration of the skin's smooth feeling, and the suppression of shine caused by sebum from makeup were evaluated using the following methods. For each item except liquid retention, a score of 2 or higher was considered a passing grade. The evaluation results are shown in Tables 1 to 4.

[0062] (Liquid retention of the sheet) Each sheet-type cosmetic composition was folded four times to create a 16-fold layer, squeezed, and the amount of liquid squeezed out (g) was measured. A smaller amount of liquid indicates less liquid composition seeping out and superior liquid retention. Here, the 16-fold method was performed by folding the sheet-like cosmetic in half so that the long side was in half (1st time, 2-fold), folding the 2-folded product in half again so that the long side was in half (2nd time, 4-fold), folding the 4-folded product in half again so that the long side was in half (3rd time, 8-fold), and then folding the 8-folded product in half again so that the long side was in half (4th time, 16-fold).

[0063] (Transferability of powders in cosmetics to the skin) In each example, the sheet-type cosmetic obtained was used to wipe bare skin (cheek area), and the transferability of the powder to the skin immediately after wiping was evaluated by touch. The evaluation was conducted by two expert panelists according to the following criteria, and the average score was calculated. 0: Equivalent to bare skin 1: Weak and smooth 2: Slightly weak and smooth 3: Smooth and silky 4: Slightly strong, smooth texture 5: Strong and smooth

[0064] (Effect of removing stickiness from skin) In each example, the sheet-type cosmetic obtained was used to wipe the bare skin (cheek area), and the stickiness of the skin immediately after wiping was evaluated by touch. The evaluation was conducted by two expert panelists according to the following criteria, and the average score was calculated. 1: Sticky 2: Slightly sticky 3: Non-sticky

[0065] (Long-lasting smooth skin feeling) In each example, the sheet-type cosmetic obtained was used to wipe the bare skin (cheek), and the smoothness of the skin three hours after wiping was evaluated by touch. The evaluation was conducted by two expert panelists according to the following criteria, and the average score was calculated. 0: Equivalent to bare skin 1: Weak and smooth 2: Slightly weak and smooth 3: Smooth and silky 4: Slightly strong, smooth texture 5: Strong and smooth

[0066] (Suppresses shine caused by sebum from makeup) Liquid foundation (Cezanne Creamy Foundation Natural Cover Type, manufactured by Cezanne Cosmetics Co., Ltd.) was applied to the face, dried for 30 minutes, then pressed with the sheet-type cosmetic obtained in each example, and the presence or absence of shine was visually evaluated after 3 hours. 0: Strong shine is observed. 1: Shine is observed. 2: Slight shine is observed. 3: A slight sheen is observed. 4: A very slight sheen is observed. 5: No shine is observed.
