What is Silk Peptide Powder?
Silk Peptide Powder is partially hydrolyzed silk fibroin powder by the degradation of silk fibroin protein. It is highly skin and hair compatible, whose molecular weight is between 500 and 10000, a white powder with good water-solubility, the ninhydrin reaction is positive. It imparts a silky, smooth feel to the skin. Use at 2 – 5% by weight in creams, lotions, shampoos, conditioners, bubble baths, shower gels, and other skin and hair care products.

- Possessing the action of inhibiting melanin production.
- Promoting the regeneration of skin tissue, guard against chapping and chemical damage.
- Inhibiting skin cancer.
- Silk peptide powder also possesses the function of antioxidants.
Silk peptide powder has a hair-caring function depends on the absorbency, absorptivity, film-forming ability, and moisturizing type it received by hair. Compared with other protolysates (collagen, bone collagen, glutin, Etc.), fibroin’s most prominent feature is that the hair easily absorbs it.
