[0035] Next, the rate of change in thickness of the nonwoven fabric before and after impregnation of the nonwoven fabric with the cosmetic composition in a sheet-type cosmetic ((dry thickness - thickness after impregnation) / dry thickness) will be described. The present inventors have newly discovered that, in a sheet-type cosmetic, the measure of the rate of change in thickness of the nonwoven fabric ((dry thickness - thickness after impregnation) / dry thickness) is effective as a design guideline for improving the favorable feel of use of the sheet-type cosmetic, specifically the balance between a firm feel in use and suppressed dryness to the skin during use. ((dry thickness - thickness after impregnation) / dry thickness) is thought to reflect the composition of the cosmetic composition and nonwoven fabric in the sheet-type cosmetic and the state of impregnation of the cosmetic composition into the nonwoven fabric, and it is thought that the smaller the value of ((dry thickness - thickness after impregnation) / dry thickness), the greater the amount of cosmetic composition remaining on the surface of the nonwoven fabric when dry.

[0036] The ((thickness when dry - thickness after impregnation) / thickness when dry) is 10% or less, preferably 9% or less, more preferably 8% or less, and even more preferably 7.5% or less, from the viewpoints of imparting a firm feel to the sheet-type cosmetic and suppressing the dry feeling of the skin when wiping a wide area. Furthermore, from the viewpoint of impregnating the nonwoven fabric with the cosmetic composition, ((thickness when dry - thickness after impregnation) / thickness when dry) may be, for example, -20% or more, preferably -15% or more, and more preferably -10% or more.

[0037] Next, a method for producing the sheet-type cosmetic material will be described. A method for producing a sheet-type cosmetic material includes, for example, a step of preparing a cosmetic composition and a nonwoven fabric, and a step of impregnating the nonwoven fabric with the cosmetic composition. In the step of impregnating the nonwoven fabric with the cosmetic composition, the impregnation method is not limited, and examples include a method of spraying the cosmetic composition onto the nonwoven fabric using a sprayer, an air gun, or the like, and a method of directly applying the cosmetic composition to the sheet substrate using a slit-type nozzle, or the like, and impregnating the nonwoven fabric.

[0038] The impregnation rate of the cosmetic composition into the nonwoven fabric is preferably 250% by mass or more, more preferably 300% by mass or more, even more preferably 350% by mass or more, and even more preferably 400% by mass or more, relative to the mass of the nonwoven fabric, from the viewpoint of suppressing a dry feeling when applying the sheet-type cosmetic to the skin. Furthermore, from the viewpoint of suppressing dripping of the cosmetic composition, the impregnation rate of the cosmetic composition is preferably 600% by mass or less, more preferably 550% by mass or less, even more preferably 500% by mass or less, and even more preferably 450% by mass or less, relative to the mass of the nonwoven fabric.

[0039] The shape, size and thickness of the sheet-like cosmetic material can be determined depending on the shape, size and thickness of the nonwoven fabric described above.

[0040] Here, in order to adjust ((dry thickness - thickness after impregnation) / dry thickness) within the above-mentioned range, it is necessary to highly control the constituent components of the nonwoven fabric and the content of each component, the manufacturing method of the nonwoven fabric, the constituent components of the cosmetic composition and the content of each component, etc. In particular, in this embodiment, the nonwoven fabric is configured to contain (A) 65% by mass or more and less than 100% by mass of hydrophilic fibers, and (B) more than 0% by mass and 35% by mass or less of hydrophobic fibers, Selecting the surface shape of the nonwoven fabric appropriately, for example, plain type; Select the basis weight of the nonwoven fabric appropriately, for example, 40 g / m 2 More than 60g / m 2 The following shall be done: The above factors can be cited as factors for controlling ((thickness when dry - thickness after impregnation) / thickness when dry) within the above range.

[0041] (packaging) In this embodiment, the package is, for example, a packaging material in which the sheet-type cosmetic material of this embodiment is housed, and is preferably sealed. There are no restrictions on the material of the packaging body, and it can be, for example, a laminated film in which a barrier layer such as an aluminum sheet (aluminum foil) or a silica vapor deposition film is sandwiched between layers, and both sides of the layer are covered with synthetic resin film layers made of, for example, polyethylene, polyethylene terephthalate, polypropylene, polyester, polyamide, polyvinyl chloride, etc. There is no limitation on the shape of the package, and it can be, for example, a pillow bag, a gusset bag, a pouch, a box, a bottle, a jar, or the like. One packaging material may contain one sheet-type cosmetic material, or two or more sheet-type cosmetic materials. Also, two or more sheet-type cosmetic materials may be contained in a connected state within one packaging material. In this case, for example, perforations may be provided in the nonwoven fabric, and the desired amount of sheet-type cosmetic material can be cut along the perforations. The sheet-type cosmetic material is stored, for example, in a folded or rolled state.

[0042] Next, a method for using the sheet-type cosmetic will be described. The method for using the sheet-type cosmetic specifically includes applying the sheet-type cosmetic to the skin, and preferably includes wiping the skin with the sheet-type cosmetic. The skin to be wiped with the sheet-type cosmetic material is, for example, skin other than the scalp, and may be the entire body, preferably the upper body such as the face, neck, and arms; or the lower body such as the legs.

[0043] Although the embodiments of the present invention have been described above, these are merely examples of the present invention, and various other configurations can also be adopted. [Example]

[0048] (Measurement of nonwoven fabric thickness change rate) (method) (i) Pressure: 20 gf / cm 2The thickness (mm) of one sheet of nonwoven fabric in the dry state was measured using a load dial gauge (PG-14J, manufactured by Teclock Corporation). (ii) Pressure: 20 gf / cm 2 The thickness (mm) of one piece of nonwoven fabric immediately after impregnation with the cosmetic composition of each example was measured using a load dial gauge. (iii) From the measured values ​​of the dry thickness and the post-impregnation thickness obtained in (i) and (ii) above, ((dry thickness - post-impregnation thickness) / dry thickness) was calculated, and this was defined as the rate of change in the thickness of the nonwoven fabric.

[0049] (evaluation) (Wipe left and right forearms twice) Four expert panelists swept the sheet cosmetic product back and forth twice on each forearm, evaluating its wiping ability on a 10-point scale, with 10 being the most refreshing feeling and the best wiping ability, and 1 being the worst, and then calculated the average score. An average score of 9.0 or higher was considered a pass.

[0050] (Dryness of the sheet during wiping) A panel of four experts evaluated the wetness (absence of dryness) of the sheet cosmetic when it touched the skin on a scale of 1 to 10, with 10 being the least dry feeling and 1 being the worst, and calculated the average score. Products with an average score of over 7.5 were considered to have passed.

[0051] (Dryness of the sheet after wiping) A panel of four experts evaluated the wetness (absence of dryness) felt after the sheet cosmetic product came into contact with the skin on a 10-point scale, with 10 being the least dry and 1 being the worst, and calculated the average score. Products with an average score of over 6.5 were considered to have passed.

[0052] [Table 1]

[0053] As can be seen from Table 1, the sheet-type cosmetics obtained in each Example had an excellent balance of effects in terms of wiping ability when wiped back and forth on both the left and right forearms twice, the dry feeling of the sheet during wiping, and the dry feeling of the sheet after wiping.
