Abstract
A skin application sheet for being impregnated with a cosmetic preparation is provided which is suitable for a face mask and so on, and causes less irritation to skin, and has good application properties. A splittable conjugate fiber web containing at least 50% by mass of splittable conjugate fibers is placed on one surface or both surfaces of a hydrophilic nonwoven containing at least 50% by mass of hydrophilic fibers and hydroentanglement treatment is conducted to split the splittable conjugate fibers into ultrafine fibers with a fineness of 0.5 dtex and to form a ultrafine fiber layer containing at least 10% by mass of the ultrafine fibers and to integrate the hydrophilic nonwoven and the ultrafine fiber layer so that a sheet is obtained. This sheet is impregnated with the cosmetic preparation and used in such a manner that the ultrafine fiber layer is a skin contact surface.

- 16. A skin application sheet for being impregnated with a cosmetic preparation wherein an ultrafine fiber layer which comprises at least 10% by mass of ultrafine fibers with a fineness of at most 0.5 dtex and is placed on one surface or both surfaces of a hydrophilic fiber layer which comprises at least 50% by mass of hydrophilic fiber, the hydrophilic fiber layer and the ultrafine fiber layer are integrated, and the ultrafine fiber layer is to be the surface which contacts with the skin.
- 17. A skin application sheet for being impregnated with a cosmetic preparation wherein an ultrafine fiber layer which comprises ultrafine fibers with a fineness of at most 0.5 dtex formed by splitting splittable conjugate fibers is placed on one surface or both surfaces of a hydrophilic fiber layer which comprises at least 50% by mass of hydrophilic fibers, wherein the hydrophilic fiber layer and the ultrafine fiber layer are integrated, the ultrafine fiber layer is to be the surface which contacts with the skin, and the ultrafine fiber layer comprises at least 50% by mass of the splittable conjugate fibers before being integrated with the hydrophilic fiber layer.

32. A method for producing a skin application sheet for being impregnated with a cosmetic preparation comprising:
-
placing a splittable conjugate fiber web comprising at least 50% by mass of splittable conjugate fibers onto one surface or both surfaces of a hydrophilic nonwoven which comprises at least 50% by mass of hydrophilic fibers; and
effecting hydroentanglement to form an ultrafine fiber layer comprising at least 10% by mass of ultrafine fibers with a fineness of at most 0.5 dtex by splitting said splittable conjugate fibers and to integrate the hydrophilic nonwoven and the ultrafine fiber layer. - View Dependent Claims (33, 34, 35)
