·Application characteristics:

1. Function of natural moistening, nourishing skin and promoting healing of skin wounds:

Application of skin protecting products enriched with silk peptide on skin can reach the effects of facial beautification and preventing many skin diseases. Clinical trials show that silk peptide have good therapy effects for several dermatosis, such as Skin Cracks, Dermatitis, Pruritus and Chloasma. The experimental results show that silk peptide has no irritability and can accelerate healing of wounds. It can prevent corrosion and damage of dusts, coating, acid and alkaline chemical substances on skin.

2.Very excellent hair-protecting function:

The protection for hair includes absorbability and adsorption, membrane, moisture retention.

Absorbability and Adsorption:

Compared to other protein hydrolysate peptide (protein collagen, bone glue protein, gelatin proteins, etc), silk peptide is nutrient-rich but can be easily absorbed by hair. Skin and hair absorb silk peptide directly and mainly by infiltration. When silk peptide concentration increases, the hair’s absorption for silk peptide will increase corresponding. For injury hair with greater adsorption capacity for the low molecular weight silk peptides, the corresponding effects for silk peptide on hair restoration and protection will be more obvious.

The silk peptide whose molecular weight ranges between 500 and 2, 000, is better at making membrane, the membrane has nice luster, feels well and spring. The method of X-radial experiment showed that the membrane made from silk peptide is β-model crystal, so that the membrane covered on the hair can be hardly washed out. This is the theory of the method how the silk peptide can protect the hair. The membrane not only avoid the damnification by the chemical material, but also can enhance the spring and glare of the hair. The membrane can finalize the shape. Compared to PVP, glue peptide and amylum under 80%RH, the silk peptide is the best in keeping the hairstyle.

Moisture adjusting and keeping:

The hair will be dry, spliting, easy to break and drop if losing some moisture.There are many hydrophilic genes, such as -OH, -COOH, -NH2, >NH, on the surface of the solid construct of its molecule. This structure shows that the silk peptide can allocate wet gene equally, and has good action of keeping hair moist and smooth.
