Benefits of technology

[0009]The mask pack can exhibit good impregnation with a liquid cosmetic preparation and good skin adhesion due to a hydrophilic nanofiber layer, and it can significantly improve a nanofiber delami

Problems solved by technology

However, such nonwoven mask packs are thick (about 15 to 50 μm) and have a small surface area per volume, and thus, can be easily detached from facial skin surfaces even under slight facial movement.
Furthermore, nonwoven mask packs exhibit a poor long-lasting effect of a liquid cosmetic preparation after

example 1

[0042]First, a rayon-PET spunlace (60 gsm) including viscose rayon and PET (weight ratio 8:2) (Namyang Textile Co., Ltd.) was prepared as nonwoven fabric.

[0043]A polyurethane adhesive (0.3 g) was coated on the nonwoven fabric to form a polyurethane adhesive-coated rayon-PET spunlace nonwoven fabric.

[0044]A solution of PAN (6.30 g), hydrophilic PU (3.15 g), hot-melt PU (1.04 g) and a pigment (0.01 g) in dimethylacetamide (89.5 g) was applied onto the adhesive-coated nonwoven fabric by an electrospinning process to thereby complete a nanofiber-coated nonwoven fabric. At this time, the mass per unit area of the nanofiber layer was adjusted to be 0.4, 0.8 or 1.1 gsm.

[0045]The nanofiber-coated nonwoven fabric was cut, and the resultant nonwoven fabric samples were folded twice and placed into cases for mask packs. A liquid cosmetic preparation (22 g, HongSam (C&Tech)) was then incorporated into the cases. The resultant packages were sealed and stored at room temperature for 3 days, 7 day...

example 2

[0046]Nowoven fabric samples obtained in the same procedure as in Example 1 except that the mass per unit area of nanofibers was 0.3 or 1.3 gsm were folded twice and placed into cases for mask packs. Then, a liquid cosmetic preparation (22 g, HongSam (C&Tech)) was then incorporated into the cases.

[0047]The resultant packages were sealed and stored at room temperature for 30 minutes to prepare desired mask pack samples.

example 3

[0048]Nonwoven fabric samples obtained in the same procedure as in Example 1 were folded twice and placed into cases for mask packs. Then, a liquid cosmetic preparation (22 g, HongSam (C&Tech)) was then incorporated into the cases. The resultant packages were sealed and stored at room temperature for one day to prepare desired mask pack samples.

Abstract

A mask pack impregnated with a liquid cosmetic preparation, being applied to a human skin surface, in particular a facial skin surface. The mask pack includes a nonwoven fabric layer and a nanofiber layer including a hydrophilic polymer, wherein said nanofiber layer is bonded to the nonwoven fabric layer.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a mask pack impregnated with a liquid cosmetic preparation, being applied to a human skin surface, in particular a facial skin surface.BACKGROUND OF THE INVENTION[0002]Mask packs are generally used in the field of cosmetics, in particular to protect the skin from external stimuli, dryness etc. Conventionally, nonwoven mask packs in which nonwoven fabrics are impregnated with a liquid cosmetic preparation have been used for application to facial skin surfaces.[0003]FIG. 1 shows a conventional nonwoven mask pack.[0004]However, such nonwoven mask packs are thick (about 15 to 50 μm) and have a small surface area per volume, and thus, can be easily detached from facial skin surfaces even under slight facial movement. Furthermore, nonwoven mask packs exhibit a poor long-lasting effect of a liquid cosmetic preparation after attachment to facial skin surfaces.[0005]In this regard, nanofiber-coated nonwoven mask packs have been sug...
