Functions and Effects
Silk Protein Peptide is the degradation product of silk protein, which is obtained by hydrolysis of natural silk underappropriate conditions. Under different control conditions, silk peptide products with different molecularweights can be obtained, and the molecular weight is about 300-5000. This molecular weight silk peptidehas good water solubility and can maintain the excellent characteristics of silk fibroin crystallization. Silkpeptide is a silk protein product with smaller molecular weight after hydrolysis of sik. Rich in 18 kinds of amino acids.
The main components are amino acids and oligopeptides. Good compatibility with water, 40% alcohol,PVA, anionic, cationic, nonionic and amphoteric surfactants. Can be absorbed by human skin.
Application Fields
01 Inhibit Melanin
Silk Protein Peptide can inhibit the activity of tyrosinase,thereby inhibiting the synthesis of melanin fromtyrosine and inhibiting the production of melanin in the skin.
02 Moisturizing
There are many hydrophilic groups (such as -OH,-COOH, -NH2, >NH, etc.) on the molecular structure of Silk Protein Peptide on the surface of the molecularthree-dimensional structure. Moisturizing effect.
03 Promote Cell Metabolism
Through the stratum corneum, it is combined withthe skin epithelial cells, and absorbed by the cells,and participates in and promotes cell metabolism.
04 Provide Hair Nourishment
Silk Protein Peptide can provide essential nutrients for thenormal metabolism of skin and hair, thereby increasing the natural luster and elasticity of skin and hair.
