·Utilizable Character
1. Skin Care and therapy:
Clinical trials show that silk peptide have good therapy effectives for several dermatosis, such as Skin Cracks, Dermatitis, Pruritus and Chloasma. It facilitate skin's regeneration, prevent skin from chap and chemical harm.
2.Absorbability and adsorption: Series experiments indicate that compared with other hydrolyzed albumen, such as collagen albumen, bone glue albumen, glutin albumen, the most peculiarity of the silk peptide is that it can be easy absorbed by hair. Radialization experiment shows that the hair absorbs silk peptide directly, the higher concentration of silk peptide leads more efficient absorbing and adsorption.
The silk peptide which molecular range 500 to 2,000, has better character of making membrane, the membrane has nice luster, fell well and spring. The method of X-radial experiment showed that the membrane made of silk peptide is βmodel crystal and for this, the membrane covered on the hair made of silk peptide is hardly washed out. This is the theory of the method the silk peptide can protect the hair. The membrane not only avoid the damnification by the chemistry material, but also can enhance the spring and glare of the hair. The membrane is some intention that can finalize the design. Compare with the PVP, glue peptide and amylum with 80%RH, the silk peptide is the best one can keep the hairstyle for a long time.
3.Adjusting and keeping wet: There are much hydrophilic genes, [such as -OH, -COOH, -NH2, >NH] on the surface of the solid construct of the molecule and this structure shows that the silk peptide equal to allocate wet gene, and have good action of keeping wet.
