Silk fibroin, a natural high molecular fiber protein extracted from silk, accounts for about 70%-80% of silk and contains 18 kinds of amino acids, among which glycine (Gly), alanine (Ala) and serine (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, permeability and moisture, slow release, and after different treatments can be obtained in different forms, such as fiber, solution, powder, film and gel.
COA:
Function: Silk is a natural protein fiber, which contains about 70% silk fibroin, and silk fibroin is rich in protein, containing 18 kinds of amino acids. Among them, leucine can accelerate the metabolism of cells, serine and threonine can delay skin aging, tryptophan and tyrosine can absorb ultraviolet rays, so the various excellent functions of silk fibroin are transferred to the fiber that lives with humans day and night, taking care of human skin, so that human beings have healthy skin. Accord with the new century human green consumption idea.
Silk fibroin, also known as silk protein, is a structural protein extracted from natural macromolecular material silk. Silk fibroin has good biocompatibility and excellent mechanical properties, so it has a wide application prospect in the field of biomedical materials. The derivatives of silk fibroin used in cosmetics are silk powder, silk peptide and silk amino acid. According to the different thickness of silk, the size of the molecular weight of silk peptide and the state of silk amino acid, it can be divided into more than 10 varieties, commonly used in cosmetics are: silk powder 144, silk powder 400, silk peptide 500, silk peptide 1000 and silk amino acid 90 and other 5 varieties. Since silk fibroin and human skin protein belong to fibrin and have many similarities in structure, the affinity between silk fibroin and its hydrolysate and human skin is unmatched by any other natural protein. The ULTRAVIOLET RAY THAT CAN BLOCK SUNSHINE ALREADY, PREVENT ITS TO THE SKIN BURN, STILL CAN USE ITS UNIQUE INTERCEPT THE ABILITY THAT HOLDS OIL CENT, PASS THE ACTION OF SILK POWDER, STRENGTHEN THE AFFINITY OF SKIN AND OILY COMPONENT, IT IS GOOD MAINTAIN BASK IN THINGS.
