Preparation method of natural silk protein facial mask

technical field

The invention relates to the field of cosmetics, in particular to a preparation method of a natural silk protein facial mask.

Background technique

Silk is a natural protein fiber and the only filament fiber among all natural fibers cotton, wool, silk, and hemp. A good cocoon can be reeled to a length of one kilometer, so the filament structure High-quality silk is usually used to make high-end clothing and silk fabrics, while the leftovers produced during the silk reeling process are cut into short fibers and then processed into silk spinning to make silk spinning fabrics (short silk fibers). The cross section of natural silk is triangular, and it is made of two monofilaments bonded by sericin. Its protein composition is silk fibroin and sericin. About 70% of silk fibroin is distributed in the center of silk, and sericin accounts for 30%. Left and right, sericin is a protein that constitutes the outer layer of silk fiber, and sericin plays a role in protecting and bonding the silk fibroin wrapped inside it. Silk fibroin includes 18 kinds of amino acids such as lysine, histidine, cystine and aspartic acid and various trace elements, which can increase the water content of the stratum corneum of the skin, promote the synthesis of collagen, and enhance the tension and elasticity of the skin , has a strong affinity with human skin and is easily absorbed by human skin. Sericin is a globular protein composed of 18 kinds of amino acids such as serine, aspartic acid and glutamic acid. Sericin protein has the property of inhibiting tyrosinase activity, so it can prevent the formation of melanin in the skin, whiten the skin, Prevents the skin from being damaged by ultraviolet rays in the sun, so sericin is a valuable natural cosmetic ingredient.

With the improvement of living standards, facial masks have changed from an original luxury consumer product to an essential skin care product for modern people. Silk, as a natural animal protein, has a great similarity with human skin. Compared with other proteins, it is easier to be absorbed by the human body, and plays the role of whitening and moisturizing. In addition, the tyrosine and phenylalanine contained in silk have a good absorption effect on ultraviolet rays, and have the effect of sun protection and skin care. Therefore, silk has also become a popular mask substrate in the mask industry.

Currently commercially available silk masks mainly use the manufacturing process of non-woven fabrics, and the production process of non-woven fabrics is more complicated: mainly use silk spinning raw materials (ie leftovers in silk reeling, waste silk, cotton, etc.), after removing Miscellaneous, cutting, degumming (or glue fixing) refining, carding, adding antistatic agent, adjusting temperature and humidity, and then entering the spunlace (or acupuncture) production line. Most of these silk spinning raw materials have undergone multiple physical and chemical actions (high temperature, high pressure, chemical additives). Although sericin is still retained, the protein has undergone multiple denaturation and refolding processes, and most of the activity of sericin protein It has long been lost and cannot achieve the desired cosmetic effect. In the traditional process of silkworm cocoons forming mask substrates, silkworm cocoons must be cooked at high temperature (steaming). During this process, a large amount of sericin will be lost and denatured, resulting in great waste, and its skin care effect is not ideal, and the formed silk mask Due to the loss of sericin, the structure is loose, easy to deform during use, and inconvenient to use. In addition, the silk non-woven fabric produced by the current spunlace (or acupuncture) line is generally thick and heavy, resulting in poor adhesion between the silk mask and the skin, unsatisfactory use effect, and loss of its skin-friendliness. Therefore, how to simply obtain a silk mask with good skin care effect has been the research direction of people in the industry always. Public literature also reports some silk facial masks, such as:

After research, it is found that the above-mentioned publicly reported documents all use silkworm cocoons as raw materials when preparing silk facial masks. The processing flow is long, the silk is easily damaged, and the required natural protein cannot be maintained.

Contents of the invention

The purpose of the present invention is to provide a pure mulberry silk protein mask with short processing flow, not easy to damage silk, and good skin care effect and its preparation method.

In order to achieve the above object, the technical scheme that the present invention takes is:

A preparation method of natural silk protein facial mask, which adopts the following steps:

(1) After the cooked silkworms have defecated, put them on the silk spinning net, and let the cooked silkworms spit 5-8 layers of silk evenly on the silk spinning net; before putting the cooked silkworms on the silk spinning net, they must wait After defecating, put it on the silk-spinning net and let it spin silk, which can prevent cooked silkworms from polluting the silk-spinning net by defecation before spinning, and thus contaminate the silk; silkworm babies gradually show the characteristics of maturity when they reach the end of the fifth instar: first, they excrete The feces in the feces changed from hard to soft, from dark green to leaf green; appetite decreased, and the amount of food eaten decreased; the front part of the digestive tract was empty, and the chest became transparent; and then completely stopped eating, the body shortened, and the abdomen also tended to be transparent. The chest is lifted up, the mouth spits out silk threads, and it swings up and down to find a place for cocooning. Such silkworms are called cooked silkworms.

(2) After the silk spinning with cooked silkworms is finished, remove the dust and sundries on the silk, and peel off the silk from the silk spinning net;

(3) Cut the stripped silk according to the shape of the mask to obtain mask-shaped silk;

(4) Put the mask-shaped silk in a device capable of steaming water, steam the silk for 3-5 minutes with water vapor, and exude silk protein to the surface of the silk, and keep the temperature of the water vapor between 100°C and 105°C;

(5) Put the steamed mask-shaped silk in a microwave sterilizer for microwave sterilization for 5-6 minutes; before microwave sterilization, the mask-shaped silk needs to be tested for silk protein exudation, and silk protein exudation is immediately It can be sterilized by microwave; the storage time is guaranteed to be more than 3-5 months.

(6) Pack the sterilized mask-shaped silk according to the traditional mask packaging process to obtain a pure mulberry silk protein mask.

The mesh width of the spinning net is 1-3 mm, and the thickness of the spinning net is 0.5-1 mm.
