FIG. 2 is a photograph of a color bio-cellulose sheet colored by using an extract of Momordica chinensis according to an embodiment of the present invention.
FIG. 3 is a photograph of a color bio-cellulose sheet colored using a judgment (Pandanus amaryllifolius) extract according to an embodiment of the present invention.

In one aspect, the invention is directed to a method of making a color bio-cellulosic sheet. The method for producing a color bio-cellulose sheet according to the present invention comprises the steps of: inoculating a culture solution containing a bio-cellulase producing strain in a container having a size of 30 cm to 35 cm and a length of 30 cm to 35 cm to produce a bio-cellulose having a thickness of 0.5 mm to 2.0 mm; Collecting the produced bio-cellulose, and stacking 100 collected bio-cells in a mesh bag; Stacking the plurality of mesh bags including the bio-cellulose laminate in a vertical direction and compressing the same at a predetermined weight to adjust the thickness of the dehydrated and bio-cellulose sheet; Preparing a liquid for extracting a natural color of the bio-cellulose sheet, and coloring the bio-cellulose sheet with the prepared natural extract liquid; And washing and preserving the colored bio-cellulosic sheet.

The biocellulose of the present invention is a cellulose made by culturing a microorganism and may be referred to as a microbial cellulose, and is used as a material for an image processor or a mask pack for medicines. Bio-cellulose is a polymer in which glucose is bonded at -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.

For the bio-cellulose of the present invention, for example, fruit juice containing sugar and acetic acid may be used as a culture solution, and microorganisms belonging to various classes may be used to achieve the effect of the present invention. The microorganism may be, but not limited to, microorganisms such as one or more of acetobactor sp., Rhizobium sp., Or Agrobacterium sp. The culturing conditions of the microorganisms are incubated at 20 ° C to 40 ° C for 5 to 10 days in order to maintain the optimum growth condition of the microorganisms producing the bio-cellulose. That is, when the temperature of the microorganism is lowered to below 20 캜, the temperature is too low to produce the desired bio-cellulose because the microorganism does not grow well. Even if the temperature exceeds 40 캜, the temperature is too high, It is difficult to produce biocellulose which has an adverse effect. In the embodiment of the present invention, the bio-cellulose is produced using the acetobactor xylenol.

In the present invention, in order to easily control the thickness of a bio-cellulose sheet to be described later, the bio-cellulosic culture container is cultured in a container having a size of, for example, 30 to 35 cm and a length of 30 to 35 cm, Production. The produced bio-cellulose is stacked in a mesh bag for 50 to 200 sheets, and a plurality of mesh bags including the bio-cellulose laminate are vertically stacked. The mesh bag laminate is compressed to a weight of 0.8 to 1.2 ton to be dehydrated, and the thickness of the bio-cellulose sheet can be adjusted to 0.1 mm to 0.6 mm through weight control. If necessary, the bio-cellulose sheet can be washed several times using purified water.

The present invention uses a natural extract liquid to color a bio-cellulose sheet to produce a color bio-cellulose sheet. The thickness-adjusted bio-cellulose sheet is immersed in a natural extract solution to prepare a color bio-cellulose. In one embodiment of the present invention, the plant used for preparing the natural extract liquid is Beetroot, Momordica chinensis or Pandanus amaryllifolius. Fig. 1 is a color bio-cellulose sheet colored by bits, Fig. 2 is a color image, and Fig. 3 is a color image. The natural extract liquid of the present invention can be prepared by using a common general method of manufacturing plant extracts, and is not particularly limited. For example, it may be an ultrasonic extraction method, a reflux cooling extraction method, a hot water extraction method, or a method in which the above solvent is used as an extraction solvent by a known method (see, for example, Nomura T, 1988, etc.). In one embodiment, the condition for staining is that the bio-cellulose is immersed in the natural extract solution for 2 hours to 4 hours at room temperature, then the solution in which the bio-cellulose is immersed is heated at 90 ° C to 100 ° C for 30 minutes and then washed with purified water Repeat for more times.

Bio-cellulose is easily contaminated and decayed due to external pollution sources, so it is subjected to a preservative treatment process to be used as a mask pack sheet for cosmetics. In one embodiment, the resulting color bio-cellulose sheet is washed three or more times with purified water and then subjected to a preservative treatment process. Wherein the preservative treatment is one or more selected from the group consisting of phenoxy ethanol, methyl paraben, ethylparaben, propylparaben, butylparaben and 1,2-hexanediol, and the at least one substance is added to purified water The bio-cellulose sheet is immersed and treated. In one embodiment, the aqueous solution contains 0.1 to 0.3% by weight, and the immersion is conducted for 2 to 30 hours. The color bio-cellulose sheet completed through the preservation treatment can be stored for a long time, and various cosmetic materials can be applied.

The cosmetic material applicable to the bio-cellulose sheet according to the present invention is not particularly limited and may include conventional additives such as antioxidants, stabilizers, solubilizers, vitamins, pigments and / or flavors.

The color bio-cellulose sheet manufactured by the color bio-cellulose sheet manufacturing method of the present invention can be processed into a mask form using a molding machine or the like to produce a mask pack for a face. In order to obtain the design of the mask pack sheet, a bio-cellulosic can be obtained in a completed design form by engraving a face-shaped design on a tray during culturing. Folding, inserting, filling and packaging processes, and gamma-ray irradiation for sterilization are performed for the production of cosmetic mask packs.
