Problems solved by technology

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

Embodiment 1

[0024] The preparation of embodiment 1 silk facial mask, completes according to the following steps:

[0025] (1) select a certain amount of fresh cocoons (containing silkworm chrysalis, oval);

[0026] (2) Cocoon washing: wash off the dust and sundries on the cocoons with water.

[0027] (3) Cocoon melting: put the cleaned cocoons into the compound solution of alkaline protease 2709 with a mass concentration of 0.1% and papain with a bath ratio of 1:100, and soak for 48 hours at 20-60°C to make silk The glue is fully swollen and the cocoon layer is opened.

[0028] (4) Peeling the cocoon: transfer the swollen cocoon to clear water, gently tear the cocoon layer by hand, and remove the silkworm chrysalis.

[0029] (5) Film formation: 3 silkworm cocoons that have been removed from the silkworm chrysalis are placed on the arched mold one by one to make a silk mesh film. According to the required thickness, one or more silkworm cocoons can also be used to make an omentum.

Embodiment 2

[0032] The preparation of embodiment 2 silk facial mask, completes according to the following steps:

[0033] (1) Cocoon drying: 25kg of fresh cocoons were dried at 60°C.

[0034] (2) Cocoon washing: wash off the dust and sundries on the cocoons with water.

[0035] (3) Melting cocoons: put the fresh cocoons after cleaning in a vacuum tank, after vacuuming, inject 500 kg of a neutral protease solution with a mass concentration of 5%, soak at room temperature for 48 hours, and the bath ratio is 1:20 to make sericin Fully swollen, the cocoon layer opens.

[0036] (4) Cocoon peeling: the swollen cocoon is transferred to an aqueous sericin solution with a mass concentration of 0.5%, and the cocoon layer is gently torn off by hand to remove the silkworm chrysalis.

[0037] (5) film forming: 5 silkworm cocoons that have been removed from the silkworm chrysalis are placed on the arched mold successively to make a silk mesh film. According to the required thickness, one or more sil...

Embodiment 3

[0040] The preparation of embodiment 3 silk facial mask, completes according to the following steps:

[0041] (1) Select a certain amount of fresh cocoons.

[0042] (2) Cocoon washing: wash off the dust and sundries on the cocoons with water.

[0043] (3) Cocoon melting: put the cleaned cocoons into a 2% papain solution, soak them at 20-60°C for 0.5h, bath ratio 1:40, fully swell the sericin, and open the cocoon layer.

[0044] (4) Cocoon peeling: the swollen cocoons are transferred to an aqueous sericin solution with a mass concentration of 50%, and the cocoon layer is gently torn apart by hand to remove the silkworm chrysalis.

[0045] (5) Film formation: 3 silkworm cocoons that have been removed from the silkworm chrysalis are placed on the arched mold one by one to make a silk mesh film. Depending on the required thickness, one or more cocoons can also be used to make the omentum.

[0046] (6) Drying: dry naturally or at a low temperature below 60°C.

Abstract

The invention discloses a method for manufacturing a high-activity silk mask by use of silkworm cocoon. The method is characterized by comprising the following steps: (1) cocoon cleaning: washing away dust and sundries on cocoon with clear water; (2) cocoon dissolving: placing the cleaned silkworm cocoon into a protease solution with the concentration of 0.1-5%, and enabling silk gum to be fully swelled and a cocoon shell to be opened; (3) cocoon stripping: pulling apart the cocoon shell to remove silkworm chrysalis; (4) film forming: sleeving the silkworm cocoon from which the silkworm chrysalis is removed on an arch-shaped die to make a silk web; (5) drying: naturally airing or drying at low temperature; and (6) punch forming. The method is short in technological process and simple to manufacture; the whole technological process is completed at low temperature without soaking in an alkali liquor or high-temperature cooking, so that the protein activity is preserved to the utmost extent, silk gum is not subject to denaturation or loss, and the manufactured mask is excellent in compactness and convenient to use.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a method for making a highly active silk mask by using silkworm cocoons. Background technique [0002] Mask is an important category in current skin care products. Its main function is to maintain the skin. Through the nutritional ingredients of the mask itself, it can achieve the effects of whitening, moisturizing, anti-wrinkle, and anti-aging. [0003] As a natural animal protein, silk has a great similarity with human skin. Compared with other proteins, silk is more easily 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. [0004] However, the fly in the ointment is that silk protein is easily inactivated, and its skin care effect is greatly reduced after inactivation. At present, most of the...
