Product Description
The sericin peptide is freshly chipped cocoon, after degumming, the silk and gum are separated, the silk gum is hydrolyzed into small molecules of silk gum peptide by enzyme, and then the pure product silk gum hydrolysate is obtained by degumming, and the pure product silk gum peptide hydrolysate is concentrated to a certain concentration, and then the finished silk gum peptide powder is obtained by spray drying. The molecular weight of silk gum peptide is around 3000d, and the silk gum product with this molecular weight has better water solubility and faster film formation.
1.Moisturizing. Silk gum is a natural moisture-absorbing material, and research shows that both silk gum and silk elements have good moisture absorption, and both can naturally form a film on the skin surface to prevent excessive evaporation of water, and play a role in regulating the wetness of the small space on the body surface, when the external humidity is large, the film can absorb part of the water, and when the external world is too dry, the film can release part of the water, through non-stop absorption and release, so that the skin moisture content is maintained in an optimal The membrane keeps the skin's moisture content at an optimal level through constant absorption and release.
2.Anti-aging, prevent cell aging and promote collagen production. According to the in vitro culture test of dermal fibroblasts and ELISA, the addition of 10kD-20kD water-soluble silk gum in the culture medium can increase the collagen production of these cells by 10%.
3.It has strong antioxidant properties and tyrosinase inhibition. By quantitative proteomic analysis, silk gum protein inhibited melanin synthesis through the MITF-tyrosinase regulatory axis in B16 melanoma cells.Norinisa et al. found that silk gum had an inhibitory effect on tyrosinase activity by adding 0. 5% and 1. 0% mass fraction of L-3,4-dihydroxyphenylalanine and mushroom tyrosinase, respectively, to a phosphate buffer containing L-3,4-dihydroxyphenylalanine and mushroom tyrosinase. The silk gum solution with a mass fraction of 0. 5% and 1. 0%, respectively, reduced the tyrosinase activity by 76% and 50%, respectively, compared to the blank control group. The results of this study showed that silk protein not only has whitening effect, but also has good effect in removing spots
It repairs damaged hair, has better hair absorption and permeability, can improve split ends and frizz, and also enhances the flexibility and tensile strength of hair and improves the natural luster of hair. Research shows that silk gum and silk hydrolysate acylation can be made into acylated amino acids, silk protein N-acylated amino acids can promote hair growth, keep the skin moist, promote subcutaneous blood flow, and is an excellent functional ingredient for hair care products
