Moisturizing and repairing facial mask containing active polypeptides and preparation method thereof

[0070] In a most preferred embodiment, the preparation method of the active polypeptide comprises the following steps:

[0071] (1) Clean the submucosa matrix of the porcine small intestine, divide it into strips with a length of 10 cm and a width of 2 cm, and process it at 120° C. for 30 minutes to obtain tissue samples;

[0072] (2) Immediately place the above-mentioned tissue samples at -80°C for 24 hours, then thaw the tissue samples with warm water at 30°C at a ratio of 10:1, and repeat this cycle for 3-5 times to obtain the thawed tissue samples;

[0073] (3) Physically pulverize the above-mentioned thawed tissue samples at -196°C to prepare powder particles with a particle size below 200 mesh;

[0074] (4) Mix the above powder particles in pure water at a mass ratio of 4:100, and emulsify at 21000 rpm for 5 minutes to obtain a slurry;

[0075] (5) Heat the above slurry to 100°C for 30 minutes, add an appropriate amount of pure water after cooling and heat to 100°C for 20 minutes, then filter with nylon gauze with a pore size of 30 μm, collect the filtrate, and freeze-dry to obtain a powder semi-finished product;

[0076] (6) The above powder semi-finished product is irradiated with 30KGy to obtain the active polypeptide.

[0077] After a long period of research, the inventors found that the submucosal matrix of the pig small intestine was subjected to high-temperature sterilization and degreasing, followed by cryogenic treatment for 3-5 times, and then immediately placed at -196°C for ultra-low temperature crushing, which can be crushed into particles of a certain size , and can be hydrolyzed into small molecule polypeptides to the greatest extent without affecting the biological activity of small molecule polypeptides. High-speed emulsification of powder particles, filtration, and freeze-drying can further obtain small molecular polypeptides with better quality. Finally, irradiation treatment is used to play a sterilizing effect again, thereby enhancing the quality of the small molecule polypeptide complex. The molecular weight is continuously reduced, and finally the effect of transdermal absorption can be achieved.

[0078] polysaccharide

[0079] The polysaccharide of the present invention is a polysaccharide high molecular carbohydrate composed of sugar chains bound by glycosidic bonds and at least more than 10 monosaccharides.

[0080]In one embodiment, the polysaccharide is selected from the group consisting of gum arabic, xanthan gum, dehydroxanthan gum, sclerotinia, hydrolyzed sclerotinia, carrageenan, locust bean gum, gellan gum, pectin, Bio-glucose gum-1, bio-glucose gum-2, bio-glucose gum-3, bio-glucose gum-4, bio-glucose gum-5, β-glucan, glycosyl trehalose, tremella polysaccharide, pullulanase polysaccharide, Alcaligenes polysaccharides, polyamino acid polysaccharide condensates, zymosan, soluble proteoglycans, aloe vera leaf polysaccharides, tuberose polysaccharides, euglenophyllum polysaccharides, senna angustifolia polysaccharides, mannan A mixture of one or more of sugars, fructooligosaccharides, fructans, succinoglycans, glycosphingolipids, glycogen, sucrose, and starch.

[0081] In a preferred embodiment, the polysaccharide is a mixture of bioglucan gum-1 and mannan.

[0082] In a preferred embodiment, the mass ratio of bio-glucose gum-1 to mannan is 1:(0.5-1.5).

[0083] In a most preferred embodiment, the mass ratio of bio-glucose gum-1 to mannan is 1:1.

[0084] The bio-glucose gum-1 is a linear bio-polysaccharide, which has a strong ability to bind water, and has a good water absorption effect even in a low-humidity environment. Evaporating, while having immediate and long-lasting moisturizing effects, dermatological application not only has moisturizing and soothing effects, but also gives cosmetics a soft and silky skin feel. At the same time, it has sensitizing properties as it promotes the removal of blunt macrophages from the infected site by competitively inhibiting MIF (macrophage motility inhibitory factor). In addition, it also has a pleasant skin feel, can regulate the user's emotions, and give the user a pleasant sensory experience and a feeling of happiness.

[0085] The mannan has a very strong water-locking and moisturizing ability, exerts an efficient skin care and moisturizing function, and has no sticky feeling, and has anti-aging and anti-oxidation effects.

[0086] The mannan was purchased from Shanghai Huixin Biotechnology Co., Ltd., with the brand name SC.

[0087] The bio-glucose gum-1 was purchased from Youke Biotechnology Co., Ltd., and the brand name is AQUATECH-S.

[0088] After long-term research, the inventors found that choosing the mixture of biological sugar gum-1 and mannan as the raw material for the preparation of the mask liquid can ensure the stability of the mask viscosity, and can also improve the stability of the active polypeptide and promote the penetration of the polypeptide. , so as to ensure that the mask can penetrate into the skin care, improve the suppleness of the skin, make the skin smooth and delicate, and achieve the anti-aging effect. The possible reason is that if mannan is added alone, its viscosity is small and its fluidity is large. If bio-glucose gum-1 is added, it can not only solve the above-mentioned problem of low viscosity of mannan, but at the same time, bio-glucose gum-1 can also It can deeply repair the skin and improve the skin's immunity. In addition, the use of bio-glucose-1 and mannan together can enhance the stability of the polypeptide. The possible reason is that the linear high-molecular sugar and the branched high-molecular sugar form a network of hydrogen bonds with the polypeptide, thereby The natural conformation of the polypeptide is stabilized, so the activity of the biological polypeptide can be maintained for a long time and the degradation of its structure can be prevented.

[0089] sugar isomers

[0090] The sugar isomers described in the present invention, also known as water-locking magnets, are colorless or yellowish transparent liquids, a natural humectant extracted from sugarcane sugar complexes, and assist moisture in binding horns in the stratum corneum protein to achieve moisturizing effect; it is also a good water retaining agent and emollient, which has the ability to repair epidermal cells and enhance skin hydration. Widely used in various skin and hair cosmetics. In skin cosmetics, it has good skin humidity adjustment function and long-term moisturizing effect, and the effect can be maintained until the cutin naturally peels off, moisturizing and relieving irritation.
