Application Characteristics:
(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 Function
The hair care function of silk peptide is mainly reflected in the
absorptivity, 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
peptide 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 **0 and
2,**0 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 *0% RH, using silk peptide 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
moisturizing factor, it can also adjust the moisture of little
space on the hair surface, making the hair soft and
smooth.
