Silk Peptide Powder

What is silk peptide?

Silk Peptide Powder is a degradation product of silk protein, which is obtained by hydrolyzing natural silk under appropriate conditions. Depending on the control conditions, silk peptide products of different molecular weights can be obtained, all of which are transparent light yellow liquids with molecular weights ranging from about 300 to 5000.

The molecular structure of silk peptide has many hydrophilic groups (such as -OH, -COOH, -NH2, >NH, etc.) on the surface of the molecular three-dimensional structure. This structure shows that silk peptide is a natural humidity-regulating factor and has good Moisturizing effect. Tests have shown that under the conditions of temperature 27, relative humidity 86% RH, and moisture absorption time 12 hours, the moisture absorption rate of a silk peptide solution with a concentration of 2.5% is equivalent to the moisture absorption rate of a glycerol concentration of 48%. That is, adding a small amount of silk peptide solution to cosmetics can achieve good moisturizing and hygroscopicity. Other tests have shown that silk peptides have extremely strong penetrating power. After being applied to the skin for about 10 seconds, small molecule silk peptides can penetrate into the stratum corneum of the skin and exert a moisturizing effect. After passing through the stratum corneum, they will combine with skin epithelial cells and be absorbed by the cells. It absorbs nutrients, participates in and promotes cell metabolism, and makes the skin shiny, moist, soft and elastic.

The amino acids in peptides are not only rich in content, but also complete in variety, including eight essential amino acids for the human body. When used as a food nutritional fortifier, silk peptide has the effects of anti-radiation, preventing leukopenia, reducing the body's absorption of fat and cholesterol, promoting wound healing and detoxification; when used as a cosmetic additive, silk peptide can provide skin and The normal metabolism of hair provides necessary nutrients, thereby increasing the natural luster and elasticity of skin and hair. It also has a significant moisturizing and whitening effect on the skin, and has the characteristics of fast absorption and good film-forming properties; silk peptide also Can be used in health-care toothpaste and soap.

Silk peptide has the effect of inhibiting the production of melanin in the skin, and has good skin care, moisturizing and hair care effects. Can be used in ointment, cream, lotion cosmetics and shampoo, hair care and bath products

What are the benefits?

Inhibit skin melanin production

Silk peptide has a variety of hydrophilic genes in its structure and is a natural moisturizing factor. The hygroscopicity of 25% silk peptide solution is equivalent to 48% glycerin. Genetic small molecule peptides can penetrate into the stratum corneum of the skin, quickly combine with epithelial cells, be fully absorbed by the skin, participate in and promote cell metabolism, and make the skin shiny, smooth and elastic. After being absorbed by the skin, silk peptide can inhibit the activity of tyrosine, thereby inhibiting the formation of melanin.

Tests show that silk peptides with molecular weights of 300-2000 and concentrations of 50%, 20% and 10% inhibit melanin production by 83.7%, 70.9% and 50.9% respectively. Experiments have further shown that small molecule silk peptides are more effective in inhibiting melanin production than large molecule silk peptides.

Promotes skin tissue regeneration and prevents cracks and chemical damage

Silk peptide is very effective in promoting skin wound healing. Make a wound on each side of the spine at home and apply silk peptide and saline respectively. The results show that silk peptide is non-irritating and can speed up wound healing. Cosmetics containing silk peptides also have a good effect on preventing skin chappedness. At the same time, it can reduce skin wrinkles and prevent dust, paint, acid and alkali chemical substances from invading and damaging the skin.

Tests show that under the conditions of temperature 27, relative humidity 86% RH, and moisture absorption time 12 hours, the moisture absorption rate of a silk peptide solution with a concentration of 2.5% is equivalent to the moisture absorption rate of a glycerol concentration of 48%. That is, adding a small amount of silk peptide solution to cosmetics can achieve good moisturizing and hygroscopicity. Other tests have shown that silk peptides have extremely strong penetrating power. After being applied to the skin for about 10 seconds, small molecule silk peptides can penetrate into the stratum corneum of the skin and exert a moisturizing effect. After passing through the stratum corneum, they will combine with skin epithelial cells and be absorbed by the cells. It absorbs nutrients, participates in and promotes cell metabolism, and makes the skin shiny, moist, soft and elastic.

Excellent hair care function

The hair care function of silk peptide depends on its ability to be absorbed and adsorbed by the hair, film-forming, and moisturizing.

The molecular structure of silk peptide has many hydrophilic groups (such as -OH, -COOH, -NH2, >NH, etc.) on the surface of the molecular three-dimensional structure. This structure shows that silk peptide is a natural humidity-regulating factor and has good Moisturizing effect.

1. Absorbency and adsorption

Compared with other hydrolyzed proteins (collagen, collagen, gelatin, etc.), the biggest feature of silk peptide is that it is easily absorbed by the hair. The absorption of silk peptide into the skin and hair mainly relies on penetration and is direct. As the concentration of silk peptide increases, the absorption of silk peptide by the hair will also increase accordingly. If the hair is damaged, the absorption and adsorption capacity of low molecular weight silk peptides will be greater, and accordingly the repair and protection effects of silk peptides on the hair will be more obvious.

Silk peptides with a molecular weight of 300-2000 have excellent film-forming properties on hair, and the film has a unique luster. The hair feels good and elastic. X-ray diffraction method shows that the film formed by silk peptide is β-type crystal, which can increase the elasticity and luster of hair. At the same time, it can also be used as a hair styling agent. Comparing PVP, collagen peptide, starch aqueous solution and silk peptide, under humid conditions of 80% humidity, using silk peptide as a styling agent can keep the hair in good style for a long time.

2. Adjust moisturizing properties

When hair loses a certain amount of moisture, it will become dry, split, and easily break and fall off. Silk peptide forms a film on the surface of the hair to prevent excessive evaporation of water. As a natural humidity-regulating factor, it can also regulate the humidity of the small space on the surface of the hair, making the hair soft and shiny.

Application direction

Application in cosmetics

1. Moisturizing and skin care

Silk peptide Powder contains more than ten kinds of amino acids that are very similar to the amino acids contained in the skin. It has no irritating effect on the skin and is an excellent additive. It can promote skin metabolism, reduce fine wrinkles on facial skin, delay skin aging, etc. It has obvious effects on skin whitening, moisturizing and nutrition, and it also has certain therapeutic effects on certain skin diseases.

2. Radiation protection, sun protection and anti-aging

Adding silk peptides to skin care cream has the effect of absorbing ultraviolet light, and its attractiveness is comparable to that of anti-sun and sunscreen skin care products on the market.

3.Hair care

Silk peptide forms a film on the surface of the hair to prevent excessive evaporation of water. As a natural humidity-regulating factor, it can also regulate the humidity of the small space on the surface of the hair, making the hair soft and shiny.

Application of silk peptide in textile processing

As early as the 1950s, silk peptides were widely used as retarding agents in silk dyeing. Silk peptide can also be used as a hydrophilic and moisturizing finishing agent for polyester fabrics. The effect of this natural hydrophilic finishing agent is very obvious. Because the biggest disadvantage of polyester fabric is poor moisture absorption and breathability, it is easy to generate static electricity, and silk peptide is an amino acid condensation polymer containing many hydrophilic groups. After the polyester fabric surface is treated with silk peptide liquid, the silk peptide self-crosslinks and adheres to the fabric surface, thereby greatly improving the moisture absorption, breathability and antistatic properties of the polyester fabric, significantly improving wearing comfort and preventing the harm of static electricity.
