Problems solved by technology

[0004] At the same time, during the preparation process of silk or silk protein, a large amount of waste liquid such as lye will be produced, which further increases the production cost of the enterprise.
In addition, during the silk preparation process, a large amount of sericin protein is removed, resulting in that this part of sericin protein cannot be well utilized
When preparing facial masks, some manufacturers will use sericin protein in the mask essence to improve the functionality of the mask. These sericin proteins are often recovered from lye and contain some chemical substances, which can easily cause skin allergies

Embodiment 1

[0046] A natural yellow flat silk mask made by the following steps:

[0047] (1) Place the silkworm of the natural yellow cocoon silkworm variety "Jinqiu×Chuyue" that is about to spin on a glass plate, and remove the silkworm after spinning to obtain natural yellow flat silk with a thickness of about 0.5mm, using physical methods ( Ultraviolet sterilization) cut into the shape of ordinary mask after sterilization.

[0048] (2) Soak the cut planar silk in 100ml of sterilized water for 12 hours at 4°C to fully soften it.

[0049] (3) Transfer the soaked and softened yellow planar silk into a 2% sericin essence (aqueous solution of 2% sericin protein) in a wet state (drained until no water drips), at a temperature of 4 Soak for 5 hours under the condition of ℃, take out and drain the liquid, dry in an environment with a temperature of 25 ℃ and a humidity of 40% for 1 hour, then put it into a new 2% sericin essence and soak it, repeat 4 times.

[0050] (4) After draining off exc...

Embodiment 2

[0052] A kind of flat silk mask of silkworm, is made by following steps:

[0053] (1) Place the silkworm of a common variety that is about to spin silk on a flat wooden board, remove the silkworm after silk spinning, and obtain white flat silk with a thickness of about 0.3 mm, which is cut into the shape of an eye mask after sterilization.

[0054] (2) Soak in 0.05% sodium bicarbonate solution at room temperature for 10 minutes to make the sericin fully swell, take it out and drain it, soak it in deionized water and wash it several times to remove the residual sodium bicarbonate.

[0055] (3) Soak the softened planar silk in 2% aseptic silk fibroin essence (2% silk fibroin aqueous solution) for 2 hours, take it out and drain for 10 minutes at 40% humidity and 25°C (for the first time), soak in 3% aseptic silk essence for 2 hours, take it out and drain for 10 minutes at 40% humidity and 25°C (second time), place in 4% aseptic Soak mycelium essence for 2 hours (the third time),...

Abstract

The invention discloses a preparation method of a silk mask. The preparation method comprises the following steps of (1) enabling silkworms to uniformly spin on the surface of a support piece to obtain planar silk; (2) softening the planar silk; (3) soaking the softened planar silk in essence to enable the planar silk to fully absorb effective components in the essence; and (4) properly draining the planar silk fully absorbing the essence to obtain a planer silk mask body. Compared with common silk, the planar silk material is used as the mask substrate, so that on one hand, the complex process of silk reeling textile retreatment is omitted, the natural components and functions of silk protein are maintained to the maximum extent, the manufacturing cost is greatly reduced, and meanwhile, the advantages of natural skin friendliness, mildness and no irritation of the mask body are further enhanced.

Description

technical field [0001] The invention belongs to the field of preparation of skin care products, and in particular relates to a preparation method and product of a silk facial mask. Background technique [0002] In recent years, the use of facial masks has become an important manifestation of modern people's pursuit of a refined life by improving their facial skin conditions. As one of the most popular skin care products on the market, facial masks use fiber materials as carriers (i.e. mask base fabrics) and carry functional substances to act on the skin to achieve moisturizing, whitening, nutrition, anti-oxidation and other effects. However, most of the facial masks on the market use chemical fibers as the base, which can easily lead to problems such as skin allergies; and pure silk facial masks are often very expensive, and the use of chemical substances in the processing process cannot be avoided when used as a facial mask. [0003] At present, when making silk facial mas...
