Silk peptide is a kind of water-soluble polypeptide substance by the degradation of silk fibroin protein, whose
molecular weight is between 500 and 10000, which is white powder with good water-solubility, the ninhydrin reaction
is positive.
Function:
(1) 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.
(2)Extremely Outstanding Hair Care FunctionThe hair care function of silk peptide is mainly reflected in the abso-
rptivity, 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 pepti de 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 silkpeptide 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 moisturizingfactor, it can also
adjust the moisture of little space on the hair surface, making the hair soft and smooth.
