The pulp, further strengthened by thermoplastic resin, can be given a suitable thickness (fluff) through embossing, and the skin will not be excessively wetted, so this is preferred. In addition, by using heat sealing to partially bond multiple sheets together, a good user experience can be provided by using sheets of soft, wipeable thickness.

[0106] From the viewpoint of improving the retention of the liquid composition and providing a good user experience when wiping, the thickness of the fabric or nonwoven fabric is preferably 0.15 mm or more, and more preferably 0.30 mm or more.

[0107] From the same point of view, the thickness of the fabric or nonwoven fabric is preferably 1.30 mm or less, more preferably 0.90 mm or less.

[0110] Based on the above viewpoint, the shape of the fabric or nonwoven fabric is specifically sheet-like. Furthermore, the planar shape of the fabric or nonwoven fabric can be, for example, rectangular. The length of a rectangular sheet is, for example, about 3 to 30 cm, preferably about 5 to 20 cm.

[0111] Secondly, the manufacturing method of sheet-shaped cosmetics will be explained.

[0112] Methods for manufacturing sheet cosmetics include, for example, the steps of preparing a liquid composition and a fabric or nonwoven fabric as a sheet substrate; and the step of permeating the liquid composition into the fabric or nonwoven fabric.

[0113] In the process of permeating the liquid composition, there are no restrictions on the permeation method. Examples include: spraying the liquid composition onto the sheet substrate using a sprayer or air gun to permeate it; or applying the liquid composition directly onto the sheet substrate using a slit nozzle to permeate it.

[0114] From the viewpoint of the refreshing feeling after wiping, the permeability 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 fabric or nonwoven fabric.

[0116] The sheet-like cosmetic obtained in this embodiment can be used as, for example, a sheet-like cleaning material.

[0117] Furthermore, the sheet cosmetic obtained in this embodiment can also be used on bare skin, for example, and in skincare methods that include wiping the skin after makeup with the sheet cosmetic.

[0118] (Packaging)

[0119] In this embodiment, the packaging body is, for example, a packaging body that contains the sheet-like cosmetic of this embodiment in packaging material, preferably sealed.

[0120] There are no restrictions on the material of the packaging body. For example, it can be made into a barrier layer with aluminum sheet (aluminum foil) or silicon dioxide vapor-deposited film, and a laminated film made of synthetic resin film layer composed of, for example, polyethylene, polyethylene terephthalate, polypropylene, polyester, polyamide, polyvinyl chloride, etc., covering both the surface and the back side.

[0121] Furthermore, there are no restrictions on the shape of the packaging; it can be made into, for example, pillow bags, stand-up pouches, resealable bags, boxes, bottles, cans, etc.

[0122] One sheet of cosmetic product can be contained within a single packaging material, or two or more sheet products can be contained within the same packaging material. Alternatively, two or more sheet products can be contained together within a single packaging material. In this case, for example, perforations can be designed into the non-woven fabric, allowing the sheet product to be cut along the perforations for use.

[0123] Sheet-shaped cosmetics can be stored in a folded or rolled-up state.

[0151] Example

[0152] (Examples 1-31, Comparative Examples 1 and 2)

[0153] Following the method described below, the liquid compositions of each example were prepared according to the combinations shown in Tables 1 to 6, and then permeated into nonwoven fabric to obtain sheet cosmetics of each example.

[0154] Here, in Tables 1 to 6, the amount of each component is the effective amount (unit: mass%).

[0155] (Method for preparing liquid compositions)

[0156] Each component is added to the aqueous phase to prepare the liquid composition for each example.

[0157] (Manufacturing method of sheet cosmetics)

[0158] After the liquid composition obtained in each example was uniformly infiltrated into the nonwoven fabric, the liquid was allowed to penetrate and permeate evenly. Regarding the permeability of the liquid composition, it was set to 300% by mass in examples other than 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 permeability was set to 200%, 250%, 400%, and 450% by mass, respectively.

[0159] The nonwoven fabrics used in each example are described below.

[0164] (Evaluation Method)

[0165] For the sheet-like cosmetics obtained in the examples recorded in Tables 1 to 6, the following methods were used for evaluation: liquid retention of the sheet, transferability of powder in the cosmetic to the skin, removal of skin stickiness, duration of skin freshness, and inhibition of oiliness caused by sebum from makeup. For items other than liquid retention, an evaluation score of 2 or higher was considered acceptable. The evaluation results are shown in Tables 1 to 4.

[0166] (Liquid retention properties of the sheet)

[0167] Each sheet-like cosmetic was folded four times to make 16 folds and then squeezed. The mass (g) of the squeezed liquid was measured. The less liquid mass, the less the liquid composition exuded and the better the liquid retention.

[0168] Here, the 16-fold is achieved by folding the sheet cosmetic in half with the long side in half (first time, half fold), folding it in half again with the long side in half again (second time, 4-fold), folding it in half again with the long side ...

[0169] (The skin transfer properties of powders in cosmetics)

[0170] The sheet cosmetics obtained in each example were applied to bare skin (cheek area), and a sensory evaluation was conducted on the transfer of the powder to the skin immediately after application. The evaluation was conducted by two professional evaluators according to the following criteria, and the average score was calculated.

[0171] 0: Equal to bare skin

[0172] 1: Weak refreshing feeling

[0173] 2: The refreshing feeling is slightly weak.

[0174] 3: Feeling refreshed

[0175] 4: Slightly stronger refreshing feeling

[0176] 5: Strong refreshing feeling

[0177] (Effective in removing stickiness from the skin)

[0178] The sheet cosmetics obtained in each case were used to wipe bare skin (cheek area), and a sensory evaluation of the stickiness of the skin immediately after wiping was conducted. The evaluation was carried out by two professional evaluators according to the following criteria, and the average score was calculated.

[0179] 1: Sticky

[0180] 2: Slightly sticky

[0181] 3: Non-sticky

[0182] (Long-lasting feeling of freshness on the skin)

[0183] The sheet cosmetics obtained in each case were applied to bare skin (cheek), and a sensory evaluation of the skin's refreshing feeling was conducted 3 hours after application. The evaluation was carried out by two professional evaluators according to the following criteria, and the average score was calculated.

[0184] 0: Equal to bare skin

[0185] 1: Weak refreshing feeling

[0186] 2: The refreshing feeling is slightly weak.

[0187] 3: Feeling refreshed

[0188] 4: Slightly stronger refreshing feeling

[0189] 5: Strong refreshing feeling

[0190] (Suppresses oiliness caused by sebum from makeup)

[0191] Apply the foundation (made by CEZANNE Cosmetics Co., Ltd., CEZANNE Foundation Cream Natural Concealer) to the face and let it dry for 30 minutes. Then, press the sheet cosmetic obtained in each case onto the skin and visually evaluate for any oiliness after 3 hours.
