Visão geral

Silk peptides are water‑soluble polypeptide substances produced by the degradation of silk fibroin protein. They generally have molecular weights ranging from 500 to 10000. It is an off‑white powder with good water‑solubility and gives a positive ninhydrin reaction.

Application Features:

1. Skin Care and Moisturization: When used as a cosmetic additive, silk peptide enhances the natural luster and elasticity of skin and hair. It effectively prevents skin dryness and promotes cell metabolism.

2. Hair Care: Silk peptide exhibits excellent absorbability and adsorptivity for hair, improving hair luster and elasticity. It delivers particularly remarkable repairing and protective effects on damaged hair: it reinforces the repair of hair cuticles and replenishes protein efficiently.

3. Food and Health‑care Products: When incorporated into food nutrient fortifiers, silk peptide exerts functions such as anti‑radiation, inhibition of leukocyte reduction, reduction of fat and cholesterol absorption by human body, wound‑healing promotion and detoxification.
