In general, in the field of cosmetics, a sheet-type mask pack is a product which can obtain a moisturizing and cleaning effect by attaching a face-shaped sheet without needing to be hand-worn. The sheet-type mask pack has a support capable of supporting the emulsion so that it can act on the skin for a long period of time as compared with general cosmetic lotion, and by enhancing the skin penetration effect of the skin effect component by the occlusive effect provided by the support This is a form of cosmetic product with excellent moisturizing effect and skin care effect.

There are generally three types of sheets of cosmetic mask packs, such as plant cellulose fibers from cotton or pulp, hydrogels made from natural polysaccharides such as agar or carrageenan, and bio-cellulose made from microbial cultures . Such a sheet is used as a fresh water body or a mask-like support of cosmetic milky lotion. Various kinds of materials and processing methods have been tried to differentiate in feeling, comfort, efficacy, and the like, which can give various feeling and efficacy depending on the kind of sheet to be applied at this time.

Among the materials of the mask pack sheet, bio cellulose produced using microorganisms is a natural material, so there is no side effect and does not cause environmental pollution. In particular, the bio-cellulose produced by the acetic acid bacteria is produced in a pure state containing no lignan or hemicellulose, unlike the plant-derived cellulose comprising a bundle of fine fibers. Unlike plant cellulose, such bio-cellulose is an ultrafine fiber and is attracting attention as an industrial material for foods and medical care due to its excellent physical strength, harmless biodegradability, high water-solubility, and transparency.

Such a cellulose has a basic structure of glucose, and is easily contaminated during transportation and production by fungi or bacterial fungi including a cellulolytic enzyme gene, which makes industrialization difficult.

In order to solve such a problem, Korean Patent Laid-Open Publication No. 2013-0086770 discloses a method for producing dried bio-cellulose. The bio-cellulose is dried by immersing the bio-cellulose in the glycol-containing compound-containing solution and can be stored for a long time at room temperature. However, the feeling of use as a mask pack is deteriorated and penetration of the lotion is not easy.

Therefore, development of a mask pack using bio-cellulose, which is easy to be stored for a long period of time as a mask pack, easy to penetrate lotion, and good in feeling when attached to the skin, is continuously required.

Therefore, It is to be understood that equivalents and modifications are possible.

In the present invention, biocellulose is a cellulosic material produced by culturing microorganisms, which is also called microbial cellulose, and is used as a material for an image processor for pharmaceuticals and a cosmetic mask pack. Biocellulose is a polymer in which glucose is bonded to β-1,4, like cellulose obtained from plants, but its fiber width is much smaller than that of plant celluloses and has a three-dimensional network structure and excellent water retention. When used in a cosmetic mask, it can give a soft texture like a hydrogel mask and a smooth fit, and it has excellent adhesion. The bio-cellulose is prepared by inoculating a microorganism into a production medium, preferably a fruit juice containing acetic acid and sugar, and culturing the microorganism in a fermenter by shaking culture to produce a microparticle cellulose in the form of particles or pellets dispersed therein .

The microorganisms used for culturing the bio-cellulose may be microorganisms belonging to various classes, and the microorganisms producing the bio-cellulose may be any one selected from the group consisting of Acetobacter, Rhizobium, and Agrobacterium. For the purpose of production efficiency, various microorganisms may be mixed and cultured. The culture conditions of the microorganism can be cultured at 20 to 40 ° C. for 3 to 15 days in order to maintain the optimal growth state of the microorganism producing the bio-cellulose.

In one aspect, the present invention provides a method of preparing bio-cellulosic fibers, comprising: preparing bio-cellulose; Immersing the prepared bio-cellulose in an aqueous solution of a thickener mixed with a single thickener or thickener mixture in purified water at a weight ratio of 0.5% to 20.0%; Pressing the bio-cellulose through the immersion step; And drying the compressed bio-cellulose.

FIG. 1 is a photograph of bio-cellulose which has been subjected to a step of immersing in an incremental mixture, and FIG. 2 is a photograph of dried bio-cellulose after drying of bio-cellulose after immersion.

The incremental mixture may include at least one selected from the group consisting of hydroxyethyl acrylate, sodium acryloyldimethyl taurate copolymer, polyacrylate-13, polysorbate 20, ) And a carbomer. The mixture is mixed with purified water at 0.5% to 20.0%, stirred, and compressed. At this time, the mixing weight ratio can be adjusted according to the feeling of the desired skin feeling, and is preferably 5%.

Hydroxyethyl acrylate and sodium acryloyldimethyl taurate copolymer are copolymer components of sodium hydroxyethyl methacrylate and acryloyldimethyltaurate monomer, To stabilize the unstable emulsified state of other components that do not mix with each other, to control the viscosity of cosmetics as a water-soluble thickener, and to reduce the transparency of cosmetics to control the degree of suspension.

The polyacrylate-13 is a copolymer component of acrylic acid, acrylamide, sodium acrylate, and sodium acryloyldimethyltaurate monomer, and forms a film on the skin, hair, etc. to smoothly wrap the skin It helps to fix and design in desired hair shape, and is used as viscosity increasing agent to control viscosity of cosmetics.

Polysorbate 20 is a mixture of sorbitol anhydride and sorbitol laurate ester, which is mainly composed of a monoester and condensed to about 20 moles of ethylene oxide. The polysorbate 20 is adsorbed on the interface of other substances that are not mixed with each other, It acts as an active substance for dispersing and is used as raw material to help stabilize emulsion.

The carbomer is also referred to as a carbopol. It is an acidic polymer compound mainly composed of acrylic acid. It can grow very transparently over a wide pH range, has little irritation to the skin, Jay.

In one embodiment of the present invention, the step of immersing further comprises adding 0.3 to 0.7% by weight of 3-hydroxybenzoic acid to the mixed thickener mixture. Preferably 0.5%.

Since the bio-cellulose is easily contaminated and corrupted due to external contaminants due to its nature, the bio-cellulose is subjected to processes such as die-off of the injected cells, removal of the culture liquid and preservation treatment process for use as a mask pack sheet for cosmetics. However, in the step of immersing the dried bio-cellulose of the present invention, a small amount of 3-hydroxybenzoic acid having antiseptic ability is prevented from being contaminated with microorganisms by adding to the mixed thickener mixture.

In another aspect, the present invention provides a method of preparing a bio-cellulosic fiber, comprising: preparing bio-cellulose; Immersing the prepared bio-cellulose in a polyisobutene solution mixed with polyisobutene in an organic solvent at a weight ratio of 0.5% to 20.0%; Pressing the bio-cellulose through the immersion step; And drying the compressed bio-cellulose. The present invention also provides a method for producing dried bio-cellulose for a mask pack sheet.

Polyisobutene is a homopolymer component of isobutylene. It forms a thin film on the surface of the skin to soften and smooth the skin and provide luster. It helps to maintain a healthy skin. As a non-water-soluble thickener, It serves to increase the viscosity. Since it does not dissolve in water, it is dissolved and used in an organic solvent. The organic solvent can be used as long as it is an organic solvent which is not harmful to the skin used for the production of cosmetics.

The bio-cellulose which has undergone the immersion step is squeezed. In an embodiment of the present invention, the squeezing step compresses the bio-cellulose to remove moisture of 90% or more.

The compressed bio-cellulose is dried with a fan to complete the dried bio-cellulose. In one embodiment of the present invention, the drying step has a drying time of 45 minutes or more.

In the pressing or drying step, the nonwoven fabric or mesh may be grounded on both sides of the bio-cellulose, the nonwoven fabric may be grounded on one side, and the mesh may be grounded on the other side. In order to maintain the sheet form of the above-mentioned mesh, non-woven fabric, and pearl beads and to facilitate processing such as molding and insertion, when the mask pack sheet of the final product is grounded so as to be detachable from the bio- After removing the mesh, non-woven fabric and perlite, they should be used.

The mesh refers to a net-like fabric which has been formed by various methods such as knitting, weaving, and knotting.

The mask pack sheet made of the dried bio-cellulose produced by the process of the present invention can be transported and produced in a dried state, thereby preventing contamination by microorganisms and being easier to manufacture than conventional dry bio-cellulose, It is possible to prevent contamination by workers, machines or airborne microorganisms during molding, folding, inserting, impregnating and packaging processes, which are essential steps for manufacturing a cosmetic mask pack. Can be easily processed. In order to obtain the design of the mask pack sheet using the bio-cellulose of the present invention, the face-shaped design is formed on the tray at the time of culturing, so that the bio-cellulose can be obtained directly in the completed design form.
