Problems solved by technology

[0004] However, this peelable mask cosmetic still does not have enough ability to remove keratin plugs and cannot meet the higher needs of users.
In other words, users are dissatisfied with general cosmetic patches for their ability to remove keratin plugs, and therefore, it is desired to develop a cosmetic patch with good removal ability

Embodiment 1

[0074] Use 58% by weight of polyvinylpyrrolidone with a weight average molecular weight of 1,200,000 as the water-soluble polymer, and 6% by weight of sorbitan oleic acid monoester (20 mol adduct of ethylene oxide, HLB15.0) as the polyoxyethylene oxide Sorbitan fatty acid ester, 34% by weight of silicic anhydride, and 2% by weight of titanium oxide, these compounds were stirred and mixed with an appropriate amount of purified water to prepare a coating solution. The coating solution was applied on the release-treated surface of a polyethylene film (thickness 50 μm), one surface of which had been treated with polysiloxane, thereby obtaining 110 g / m 2 The application amount and uniform thickness, thus forming a skin adhesive layer. Spunlaced non-woven fabric made of polyester fibers (unit weight: 40g / m 2 ) was covered on the skin adhesive layer, and then the whole was dried at 105° C. for 3 minutes to prepare a cosmetic patch with a three-layer structure. In the resulting cosm...

Embodiment 2

[0101] Use 56% by weight of polyvinylpyrrolidone with a weight-average molecular weight of 1,200,000 as the water-soluble polymer, and 6% by weight of sorbitan oleic acid monoester (20 mol adduct of ethylene oxide, HLB15.0) as the polyoxyethylene oxide Sorbitan fatty acid ester, 34% by weight of silicic anhydride, 1% by weight of titanium oxide, and 3% by weight of medicinal carbon. These compounds and an appropriate amount of purified water were stirred and mixed to prepare a coating solution. The coating solution was coated on the release-treated surface of polyethylene film (thickness 50 μm) whose surface had been treated with polysiloxane to obtain 110 g / m 2 The application amount and uniform thickness, thus forming a skin adhesive layer. Spunlaced non-woven fabric made of polyester fibers (unit weight: 40g / m 2 ) was covered on the skin adhesive layer, and then the whole was dried at 105° C. for 3 minutes to prepare a cosmetic patch with a three-layer structure.

Spunlaced non-woven fabric made of polyester fibers (unit weight: 40g / m 2 ) was covered on the skin adhesive layer, and then the whole was dried at 105° C. for 1.5 minutes to prepare a cosmetic patch with a three-layer structure. In the obtained cosmetic patch, the water con...

Abstract

A cosmetic patch comprising a carrier and providing on one surface of the carrier a skin adhesive layer comprising a wet pressure-sensitive adhesive composition comprising a water-soluble polymer and polyoxyethylene sorbitan fatty acid ester, wherein Polyoxyethylene sorbitan fatty acid ester oozes out on the surface of the skin sticking layer. Cosmetic patches do not cause pain to the skin and can fully remove keratotic plugs.

Description

technical field [0001] The present invention relates to cosmetic sheets. In particular, it relates to a cosmetic patch for removing keratotic plugs and the like. Background technique [0002] Recently, there are known cosmetic patches suitable for removing keratotic plugs from the skin, in which a skin-attaching layer (skin-attaching layer) is formed using a water-soluble polymer on one surface of a carrier layer composed of nonwoven fabric or the like. layer). Cosmetic patches are usually wetted with water and applied to the site to be applied (for example, the nose). Keep the applied cosmetic patch under these conditions for about 10 minutes, after the water evaporates, it is peeled off and removed very slowly. During these series of operations, the skin adhesive layer is dissolved or moistened in water, brought into contact with the keratinized plugs present in the pores, and then dried so that this layer is combined with the keratinized plugs and thus It is removed t...
