Silk, renowned for its luxurious feel and aesthetic appeal, offers more than just perceived value in cosmetic applications. The hydrolyzed form of silk protein, known as Silk Fibroin Peptides or Silk Protein Hydrolyzates (CAS 96690-41-4), is a scientifically validated ingredient that delivers tangible benefits for both skin and hair. As a leading supplier in China, we specialize in providing high-quality Silk Fibroin Peptides, enabling formulators to harness these advanced properties.

Understanding Silk's Composition and Hydrolysis

Natural silk is primarily composed of two proteins: fibroin and sericin. Fibroin forms the structural core, while sericin is a gummy outer layer. Through controlled hydrolysis, the silk fibroin is broken down into smaller peptide chains and amino acids. This process yields a water-soluble ingredient with enhanced skin and hair compatibility. Our manufacturing process ensures a minimum 90% purity for these valuable peptides, meeting global standards.

Key Scientific Benefits for Skincare

The unique molecular structure of Silk Fibroin Peptides translates into several scientifically proven benefits for the skin:

  • Biocompatibility and Biodegradability: Silk fibroin is highly biocompatible and biodegradable, making it a safe and sustainable choice for personal care products.
  • Moisture Retention: The presence of hydrophilic amino acid residues allows these peptides to attract and bind water molecules, acting as potent humectants. This property helps maintain skin hydration, improve elasticity, and reduce the appearance of fine lines. For formulators looking to buy ingredients that boost skin hydration, our Silk Fibroin Peptides are an excellent option.
  • UV Absorption: Research indicates that silk protein can absorb a portion of the UV spectrum. While not a primary sunscreen agent, it can complement UV filters and offer a degree of natural photoprotection.
  • Improved Skin Texture: The fine, reflective nature of silk particles, even in hydrolyzed form, can contribute to a smoother skin feel and a subtle luminosity.

Hair Care Applications of Silk Protein Hydrolyzates

In hair care, Silk Protein Hydrolyzates are equally impressive:

  • Hair Strengthening and Shine: Peptides can penetrate the hair shaft, helping to strengthen it from within and providing a protective coating that enhances shine and manageability.
  • Moisture Binding for Hair: Similar to skin, these peptides help hair retain moisture, preventing dryness and frizz, leading to softer, more lustrous hair.
  • Improved Combability: The lubricating properties of silk protein derivatives can reduce friction, making hair easier to comb and style.
