KR20160109422A - Mask pack comprising silver nano particles - Google Patents

Abstract

The present invention relates to a mask pack containing silver nano particles including: a mask pack main body (A) that is a non-woven fabric; and a cosmetic liquid immersed in the mask pack main body (A). A coating layer (C) is formed on an inner surface of the mask pack main body (A) and silver (Ag) nano particles are dispersed in the coating layer (C). The coating layer in which the silver nano particles are dispersed is formed on the inner surface of the mask pack main body (A) that is the non-woven fabric, and silver nano particles (P) are selectively dispersed in the cosmetic liquid as well in a case where the cosmetic liquid is a gel-type cosmetic liquid. According to the present invention, the silver nano particles are contained in the inner surface of the mask main body (A) that is the non-woven fabric, and thus skin whitening and sterilization effects can be excellent. In addition, the silver nano particles in the cosmetic liquid (B) are uniformly distributed in a non-agglomerated state in the coating layer (C) formed on the inner surface of the mask main body (A), and thus the skin whitening and sterilization effects can be realized throughout a face.

Description

Mask pack < / RTI > comprising silver nanoparticles < RTI ID = 0.0 >

The present invention relates to a mask pack including silver nanoparticles, and more particularly, to a mask pack including silver nanoparticles in which a skin whitening effect and a sterilizing effect are uniformly expressed throughout the user's face.

In recent years, the use of mask packs has been rapidly expanding to prevent aging of skin and deterioration of elasticity.

A mask pack main body (A), which is a nonwoven fabric which is a mask pack normally used for skin protection, and a cosmetic liquid impregnated in the mask pack main body (A).

Korean Patent Laid-Open No. 2006-0113050 proposes a cosmetic composition having a formulation similar to fresh cream as a cosmetic liquid (cosmetic composition) conventionally used in a mask pack, and suggests that such a composition can provide a new and pleasant consumption experience to consumers .

Korean Patent Laid-Open Publication No. 2007-0106115 proposes a washable cleansing cosmetic composition having elasticity, and the composition can be easily rinsed with water after use without irritation to the skin, and has elasticity so that it can provide sensual fun in appearance Lt; / RTI >

Korean Patent No. 10-0869155 discloses an emulsion-type cleanser which combines the advantages of cleansing oil and cleansing water as a unique and distinctive formulation and visually has a two-layer structure.

Korean Patent No. 10-0417874 also discloses a stable non-aqueous liquid polyhydric alcohol-type emulsion cosmetic containing water at a high concentration of 1 to 8 wt% of L-ascorbic acid.

Korean Patent No. 10-0502646 also discloses a high-performance powdered cosmetic composition in which a functional ingredient is stabilized in liposomes and stabilized in a porous powder.

The conventional mask pack impregnated in the mask pack main body A in which the conventional cosmetic liquids are nonwoven fabric has a problem that the skin whitening effect and the sterilizing effect are inferior.

The object of the present invention is to provide a mask pack in which a skin whitening effect and a sterilizing effect can be uniformly expressed throughout the user's entire face.

In order to achieve the above object, the present invention provides a method of manufacturing a mask pack, comprising: forming a coating layer (C) having silver (Ag) nanoparticles dispersed on the inner surface of a mask pack main body (A) A) is impregnated with a cosmetic liquid to prepare a mask pack.

The present invention is characterized in that the silver nanoparticles are contained in the inner surface of the mask body A in which the silver nanoparticles are nonwoven fabric so that the skin whitening effect and the sterilizing effect are excellent and the silver nanoparticles are not aggregated in the cosmetic liquid B, Is uniformly distributed in the coating layer (C) formed on the inner surface of the skin (C), so that skin whitening effect and sterilization effect are uniformly distributed over the entire face.

1 is a schematic cross-sectional view of a mask body A in which a coating layer C having silver nanoparticles dispersed on its inner surface is formed.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the mask pack according to the present invention comprises a mask pack main body A, which is a nonwoven fabric, and a cosmetic liquid impregnated in the mask pack main body A, And a coating layer (C) in which silver (Ag) nanoparticles are dispersed is formed.

The present invention includes silver (Ag) nanoparticles in a mask pack to realize a skin whitening effect and a sterilizing effect.

However, when the silver nanoparticles are added to the liquid cosmetic liquid, the nanoparticles are not uniformly dispersed in the cosmetic liquid but are unevenly dispersed, and it is difficult to evenly apply skin whitening effect and sterilization effect over the entire face of the user.

Accordingly, the present invention provides a coating layer (C) in which silver nanoparticles are dispersed on the inner surface (A1) of the mask pack body, which is a nonwoven fabric as shown in FIG. 1, so that skin whitening effect and sterilization effect .

As a method of forming the coating layer (C) in which the silver nanoparticles are dispersed on the inner surface (A1) of the main body of the mask pack, a coating solution in which silver nanoparticles are dispersed is knife coated on one surface of the mask pack main body (A) And the like can be used.

The coating solution in which the silver nanoparticles are dispersed may be composed of a binder, water and silver nanoparticles, which are water-soluble polymers, and may be composed of a water-insoluble polymer, a solvent and silver nanoparticles.

In the present invention, the content of the silver nanoparticles contained in the mask pack is not particularly limited.

In the meantime, the present invention includes an embodiment in which silver nanoparticles are contained in a gel-type cosmetic liquid when the cosmetic liquid is a gel-type.

When the cosmetic liquid is of a gel type, the addition of nanoparticles improves the dispersibility of the cosmetic liquid rather than the liquid type.

The composition of the cosmetic liquid may be a water-soluble / oil-soluble physiologically active ingredient, a moisturizing agent, a preservative, a pH adjuster, a fatty acid, an emulsifier, a surfactant, an antioxidant, a sunscreen, a pigment, a dye, May be further added, and the kind and content thereof may be appropriately selected by those skilled in the art.

Examples of the moisturizing agent include glycerin, erythritol, xylitol, maltitol glycerin, propylene glycol, 1,3-butylene glycol, sorbitol, polyglycerin, polyethylene glycol, 1,2-pentanediol, isoprene glycol, amino acid, Carotene, pectin, mannan, cardan, galactan, delamantansulfuric acid, glycocon, keratan sulfate, chondroitin, mucoitin sulfate, kerato sulfate, chondroitin, mu But are not limited to, carotenesulfate, carotenesulfate, locust bean gum, succinoglucan, calonym acid, hyaluronic acid, heparan sulfate, sodium hyaluronate, collagen, mucopolysaccharide, chondroitin sulfate, dimethylpolysiloxane, A culture supernatant of lactic acid bacteria and bifidus bacteria, and a combination thereof.

Hereinafter, the present invention will be described in more detail with reference to Examples.
