Embodiment 1

[0054] Embodiment 1: the preparation of the silk precursor produced by golden silkworm

[0055] Using the transgenic golden silkworm described in Korean Patent No. 10-1570784, specifically, using the golden silkworm transformed with a recombinant expression vector comprising a gene construct operably linked to There are marker gene regulated promoters, a marker gene, a silk protein promoter from silkworms, and a yellow fluorescent gene from siphonophores. The above-mentioned silk raw silk can be produced through the cocoon refining process as described below. Specifically, after the cocoons are shredded, 0.3% (w / v) of sodium oleate and 0.2% (w / v) of sodium carbonate are mixed at a bath ratio (the ratio of silkworm cocoons and refining solution) of 1:25. In an aqueous solution, the silkworm cocoons were treated at 100°C for one hour for refining, washed five times with hot water and distilled water, dried in an oven at 105°C, and finally produced silk precursors of golden sil...

Embodiment 2

[0056] Example 2: Manufacture of a sheet for facial masks comprising silk precursors produced by golden silkworms

[0057] 2-1: Manufacture of non-woven fabric

[0058] The fiber mixed with the silk raw silk which is the refined silk produced in the above-mentioned Example 1 is formed into a web (Web) through a carding process, and then water punching or needle punching (Needle punching) is sequentially performed , Manufactured a composite non-woven fabric for mask sheet.

manufacture example 1-2

[0059] 2-2: Production of non-woven fabrics using golden silkworm silk raw silk, tencel and pure cotton (manufacturing example 1-2 and comparative example 1-2)

[0060] Production examples 1-2 and comparative examples 1-2 described below were produced using the raw silk of golden silkworm, the raw silk of tencel, and pure cotton produced in the above-mentioned Example 1.

[0061] 1) Manufacture example 1 - set the blending ratio of golden silkworm silk precursor and tencel precursor silk to 5:5 for mixing;

[0062] 2) Manufacturing example 2 - set the blending ratio of the silk precursor of golden silkworm and tencel precursor to 7:3 for mixing;

[0063] 3) Comparative example 1 - the blending ratio of pure cotton and Tencel raw silk is set to 5:5 for mixing;

[0064] 4) Comparative Example 2 - The blending ratio of pure cotton and tencel raw silk is set to 5:5, and then mixed with a colorant (C.I.SOLVENT YELLOW82 of Hyundai Chemical, CAS No.: 12227-67-7) coating.

Abstract

The invention relates to a mask sheet comprising a silk produced from gold silkworm, and more particularly to a mask sheet comprising a silk produced from gold silkworm transformed with a recombinantexpression vector for the production of golden silk and a mask made of the mask sheet. The mask sheet comprising the silk produced from gold silkworm is not only low and stable to the irritation of the skin, but also excellent in the moisturizing power in the middle and early stage. Therefore, the mask sheet can be used as a novel makeup mask sheet.

Description

technical field [0001] The present invention relates to a sheet for facial masks comprising silk precursors produced by golden silkworms, more specifically, to a sheet for facial masks comprising silk precursors produced by golden silkworms transformed with recombinant expression vectors for production of golden silkworms and A facial mask manufactured using the facial mask sheet. Background technique [0002] Generally, in the field of cosmetics, a sheet mask is a product that does not need to be applied by hand, but is attached to the face to obtain moisturizing and cleansing effects. It is designed to cover the entire face. Mask sheets, mask sheets divided into upper / lower parts, and mask sheets designed according to specific parts such as fundus / eye corners / mouth corners, etc., appear on the market in various forms. Compared with general cosmetic emulsions, the sheet mask has a support that can hold the emulsion so that it can act on the skin for a long time, and throug...
