Silk fibroin powder, Silk fibroin protein, natural Fibroin powder, Silk sericin powder and Silk Peptide Powder are all extracted from natural silk cocoons, belonging to natural biopolymer materials. They are skin-safe, non-irritating and have good moisturizing and nourishing effects, but differ in properties and applications. This guide helps buyers make wise choices.
Key Differences: Silk Fibroin Powder vs. Silk Sericin Powder vs. Silk Peptide Powder
Silk Fibroin Powder (main component: 70-80% of silk) is water-insoluble with large molecular weight, white fine powder. It has excellent film-forming property, adhesion and silky texture, featuring structural support, barrier repair and long-lasting moisture lock. Ideal for Silk fibroin for cosmetics like high-end creams, foundations and medical materials.
Silk Sericin Powder (20-30% of silk) is water-soluble (Water-soluble silk fibroin similar attribute) with medium molecular weight, pale yellow to white powder. It has strong antioxidant, UV protection (sericin glycoside for UV protection), melanin inhibition and anti-inflammatory effects. Silk sericin for hair repair is perfect for anti-aging skincare, hair care products and soap making (sericin for soap making).
Silk Peptide Powder (hydrolyzed silk peptide, small molecular weight below several thousand Daltons) is easily soluble in water, white to pale yellow powder. It has high permeability, quick absorption and deep hydration. Suitable for silk peptide for skincare, silk peptide for hair care, silk peptide for functional food, essence, ampoules and oral beauty products.
Buyer's Selection Suggestions
Choose based on your product goals: Pursue silky texture and film-forming modification → Silk Fibroin Powder (e.g., luxury matte cream, long-wearing foundation).
Pursue bioactivity (antioxidation, whitening, repair) → Silk Sericin Powder (e.g., anti-photoaging serum, damaged hair repair shampoo).
Pursue instant absorption and high permeability → Silk Peptide Powder (e.g., quick hydrating essence, oral beauty drink).
Combination application:
Silk Fibroin + Silk Sericin (balance structural support and active protection);
Silk Peptide + Silk Fibroin (quick penetration + moisture lock).
When purchasing, confirm technical parameters like molecular weight distribution, purity, solubility, extraction process, microbial and heavy metal indicators to ensure quality.
