Hydrolyzed Silk Fibroin

Fibroin also known as: silk fibroin. Silk fibroin, a natural high polymer protein extracted from silk, contains about 70% ~ 80% of silk and 18 kinds of amino acids, among which gLY, ALA and Ser account for more than 80% of the total composition.

Silk fibroin itself has good mechanical properties and physical and chemical properties, such as good flexibility and tensile strength, breathable moisture permeability, slow release, etc., and can be obtained in different forms after different treatments, such as fiber, solution, powder, film and gel etc.

The active ingredients in the natural Hydrolyzed Silk Fibroin are released layer by layer, and penetrate into the dermis of the skin in 10 seconds, effectively inhibiting melanin production and controlling pigmentation. Promote collagen synthesis, activate cells, improve cellular immunity, promote skin metabolism, help repair damaged skin tissue, rejuvenate dull and tired skin, and restore fair and shiny skin in a very short period of time.

The protein content of silk is as high as more than 96%, composed of 18 kinds of amino acids, and its structure is very similar to human skin and hair. The small molecule silk peptides formed after the hydrolysis of silk protein can quickly penetrate into the epidermis of hair, play a role in nutrition and repair damage, and can make hair shiny and increase elasticity. Silk peptide has a high affinity for hair and good film-forming properties. It can form a protective film on the hair surface and make the hair have good flexibility.

Product Information Table

Silk protein fiber is a new type of functional fiber, which has irreplaceable unique properties and unparalleled vitality of other fibers and processed products. Various colorful silk protein fabrics that are dyed and woven are easier to sew and process into various high-end garments and to be used in the high-end home textile market. The special effect of silk protein fiber has the following five points:

First, comfort. Silk protein fiber has excellent biocompatibility with the human body. In addition, the surface is smooth and soft to the touch. Its frictional stimulation coefficient to the human body is much lower than other types of fibers. Therefore, when our delicate skin meets the smooth and delicate silk protein fiber, it follows the curve of the human body with its unique soft texture, caring for every inch of our skin thoughtfully and safely.

Second, good moisture absorption and dehumidification. Silk protein fibers are rich in many hydrophilic groups such as amine groups (-CHNH) and amino groups (-NH2), and because of its porosity, it is easy for water molecules to diffuse, so it can absorb or emit water in the air, and Stay hydrated. Under normal temperature, it can help the skin retain a certain amount of moisture and not make the skin too dry; when worn in summer, it can quickly dissipate the sweat and heat from the human body, making people feel extremely cool. It is because of this property that silk protein fibers are more suitable for direct contact with human skin.

Third, the gloss is good. The silk protein contained in the silk protein fiber is extracted from the snow-white silk extruded by silkworms. It is a pure natural product. The woven fabric has a silky luster, which is radiant after wearing.

Fourth, it has good anti-ultraviolet and heat-resistant fastness. The tryptophan and tyrosine in Hydrolyzed Silk Fibroin can absorb ultraviolet rays, so silk fibroin fibers have better anti-ultraviolet function. Moreover, because the carrier is viscose fiber, and some high-tech is used in the research and development process, the silk protein fiber has better heat resistance under the premise of anti-ultraviolet rays, and will not fade due to heat, so that the color of the colored fabric is improved. Materials are subject to change. Thereby reducing the aesthetic effect.

Fifth, the color is vivid and the wrinkle resistance is good. In terms of spinning, dyeing and finishing properties of silk protein fiber, reactive neutral dyes are the best, and are suitable for the production and processing of various textile products. The wrinkle resistance of the fabric woven by it is also significantly better than that of real silk. The silk protein fiber fabric has good physical and mechanical properties and high stability, and the fabric has little deformation in a wet state and has good wear resistance.

1. Deep whitening: go deep into the bottom of the skin, fundamentally whiten the skin without side effects;

2. Long-term moisturizing: NMF factor is ten times that of conventional plant or chemical moisturizers, continuously and efficiently replenishing moisture to the skin;

3. Nourishing and conditioning: strong penetration, providing essential nutrients for the skin, promoting cell metabolism, and improving skin quality.

4. Anti-aging and revitalizing skin: it can activate skin cells, improve microcirculation, anti-aging and anti-wrinkle, and revitalize the complexion;

5. Anti-oxidation: Effectively resist external pollution, maintain skin pH balance, and enhance skin immunity

Hydrolyzing silk can reduce surface irritation

It has been confirmed through chicken embryo experiments that silk protein can reduce the irritation of surfactants, commonly used foaming agents in shampoos, shower gels, facial cleansers and other products. When the irritation is reduced, the source of inflammatory factors is reduced. , the barrier function of the scalp is protected.

Hydrolyzed silk protein can inhibit oil secretion

Excessive oil secretion is a sign of unhealthy skin. In terms of scalp care, excessive oil secretion will lead to the proliferation of oil-loving Malassezia. Malassezia can decompose triglycerides and saturated fatty acids in sebum by secreting lipase. It is a pro-inflammatory unsaturated fatty acid. These substances penetrate into the stratum corneum and cause inflammatory stimulation of the scalp, which can cause scalp itching and dandruff. Hydrolyzed silk has a good oil control effect, which can reduce the number of Malassezia bacteria, thus reducing the signaling pathways that stimulate inflammatory reactions deep in the skin, which is beneficial to reducing the occurrence of dandruff. In addition, in terms of skin care, oil control can also prevent the occurrence of acne.

Moisturizing effect of hydrolyzed silk protein

Moisturizing is the most basic and important step in skin care and hair care. In fact, many skin or hair problems are caused by dryness. On the contrary, problems with the skin and hair can also lead to dehydration of the skin or hair, further aggravating the damage. The natural moisturizing effect of silk protein can be used in skin care and hair care functions. It is also a rare natural moisturizing ingredient.

Product Application

Mainly used in cosmetics, hair care products and masks

By rebuilding or protecting the healthy ecology of the scalp, the purpose of synergistic hair growth and hair consolidation is achieved:

1. Hydrolyzed silk protein is rich in silk protein, peptides, amino acids, etc. It has excellent hygroscopicity and water-holding properties, and can effectively prevent dry hair and scalp.

2. The sericin and macromolecule keratin in hydrolyzed silk protein can form "mud"-like cell adhesion substances on the scalp surface. It can repair epidermal cells that are about to be peeled off and delay scalp shedding. At the same time, it repairs the hair shaft, reduces hair brittleness, split ends, and shedding, and enhances hair toughness.

3. The sericin and small molecule keratin, polypeptides, peptides and amino acids in hydrolyzed silk protein can provide nutrients for hair regeneration.

Detection Method

Silk protein is extracted from natural silk by special process. Therefore, the composition and content of amino acids are one of the important indexes to measure product quality.
