Description of Silk Peptide

Natural silk peptide made from natural silk by modern and new technique. It is water-soluble 100%.It contains 18 kinds of human essential amino acids, its molecular weight generally are below 2000.

The silk peptide is used for having natural hydration and adjusting wet in the cosmetic. It can effectively restrain skin melanin with the function of nourishment skin, its good adsorbability, make it extremely and excellently protecting hair and keep hair health. The function in the cosmetics owns high effect and safety. The synthesized materials can't compare with it.

The silk peptide used for cosmetic because of the function of keeping skin humid, adjusting and making skin shine, can control skin melanin. The great absorbency will be of benefit to hair. Silk peptide has better cosmetic function and safety than other compound materials.

Silk peptide has a bright future in biomedicine remedy and biologic gas defense area.

Function of Silk Peptide

1. The natural silk peptide is soluble silk protein, containing 18 kinds of amino acids, especially the silk serine protease and amino-succinic acid, glutamic acid are all skin nurture, which are easily absorbed through epidermis to improve the nourishment of skin through epidermis cell and strengthen skin cell energy. Use the cosmetics which have Silk Peptide for a long time, can strengthen the effect of skin and delay decrepitude.

2.The natural silk peptide can restrain the activity of the beta-parahydroxy-phenylpropionic acid, the element of melanin in the skin. And it can make the skin pure without blemish.

3. The natural silk peptide is a kind of natural wet adjusting material, effectively hydration function, and makes skin full of flexibility, moisture.

4. Natural silk peptide is good treatment to dry skin, the skin scratch and the gestation scratch, protecting skin from sunlight strictly and coldly. It can promote skin organization of rebirth and wound.

5. Natural silk peptide makes a good effect as the function of cosmetic .Because the silk protein is extremely alike hair's, it can protect the hair immediately by becoming one thin but transparent protection film on the hair surface. It can increase hair flexibility, sheen and softness, and is free from the influence that water flushes.

6. Natural silk peptide with natural, the purely true quality is accepted by more and more people and has vast applied foreground in all kinds of cosmetic.

Application of Silk Peptide

1.Extremely Outstanding Hair Care Function

The hair care function of silk peptide is mainly reflected in the absorptivity, absorbability, film-forming property, humidifying and moisture retention to hair.

Compared with other protein hydrolysate (collagen, collagen protein, gelatin protein, etc.), the greatest feature of silk peptide is that it is rich in nutrition and can be easily assimilated into the hair. The absorption of silk peptide to skin and hair mainly depends on permeation. The increase of silk peptide concentration will enhance the absorptive amount to silk peptide by hair correspondingly. As for the damaged hair, it has larger absorbed dose and adsorbing capacity, which in turn silk peptide has a more obvious repair and protection effect on hair.

The silk peptide of which the molecular weight is between 500 and 2,000 has wonderful film-forming property on hair, and the film has a unique luster, while the hair feels good and elastic. X-ray diffraction method shows that the membrane formed with silk peptide is the β type crystallization, and the membrane formed with silk peptide on hair can increase the elasticity and luster of hair. Meanwhile, it can also be used as the hairspray. Comparing the silk peptide with PVP, collagen peptides, starchy solution, under the damp condition of 80% RH, using silk peptide as hairspray can keep hair in good condition for a long time.

After losing certain amount of water, the hair will be dry, vulnerable to breaking and coming off and has split ends at the same time. The membranes formed by silk peptide on the hair surface can prevent water from excessive evaporation. As a natural moisturizing factor, it can also adjust the moisture of little space on the hair surface, making the hair soft and smooth.

2.It has actions of natural moisturizing, nourishing skin and promoting skin wound healing.

As clinically proven, silk peptide has good curative effects on skin wrinkle, dermatitis, pruritus, and eliminating chloasma. The silk peptide is non-irritant and can accelerate the wound healing. Silk peptide can also prevent the skin from the erosion and damage of the chemicals such as dust, coating, acid and alkali. Therefore, frequent daubing skin with skin care products which are rich in silk peptide can achieve the cosmetic effect and prevent a wide range of skin diseases.
