Title:
LIQUID-RETAINING SHEET AND FACE MASK
Document Type and Number:
WIPO Patent Application WO/2013/187404
Kind Code:
A1
Abstract:
A liquid-retaining sheet formed from a nonwoven fiber aggregate comprising a liquid-retaining layer capable of absorbing a liquid component, in which the liquid-retaining layer comprises transparent fibers, wherein the degree of transparency as defined below is adjusted to 0.27 or less.
Transparency = degree of white (%)/basis weight (g/m2) when the water content per sheet mass has been set at 700 mass%.
The transparent fibers can comprise cellulose fibers that are essentially free of carboxyl groups. Even though the liquid-retaining sheet comprises a nonwoven fiber aggregate, it is possible to improve transparency in a wet state and to realize optimal strength in a wet state. This sheet is used in a skin care sheet or face mask impregnated by a liquid component containing a cosmetic.
