The demand for effective and naturally derived ingredients in sun care products continues to grow. Among these, Silk Protein Hydrolyzates (CAS 96690-41-4) are gaining attention for their unique properties, including a contribution to UV protection. As a dedicated manufacturer and supplier of high-quality cosmetic ingredients in China, we understand the nuanced benefits of this versatile material and how it can enhance sunscreen and daily wear SPF products.

Understanding the UV-Absorbing Mechanism of Silk Protein

Silk protein, particularly in its hydrolyzed form, possesses a molecular structure that allows it to interact with ultraviolet radiation. While not a potent standalone UV filter like chemical or mineral sunscreens, silk protein contributes to photoprotection through several mechanisms:

  • Reflection: The crystalline structure of silk fibers, and by extension its hydrolyzed components, can physically reflect some UV rays. This acts as a passive barrier.
  • Absorption: Certain amino acid residues within the silk protein chain have been shown to absorb specific wavelengths of UV light, converting the energy into heat that is safely dissipated. This absorption capability complements the action of primary UV filters.

Our Silk Protein Hydrolyzates, boasting a minimum 90% purity, are processed to retain these beneficial light-interacting properties, making them an excellent co-ingredient in sun care formulations. Procurement managers looking to buy ingredients that offer a natural, multi-functional edge will find this product highly valuable.

Synergistic Effects in Sun Care Formulations

The true strength of Silk Protein Hydrolyzates in sun care lies in their synergistic effects when combined with conventional UV filters:

  • Broad Spectrum Support: They can help to broaden the spectrum of protection, particularly against certain UVA and UVB wavelengths, when used alongside ingredients like zinc oxide, titanium dioxide, or organic UV filters.
  • Improved Skin Feel: Silk proteins are known for their smooth, silky feel. Incorporating them can enhance the cosmetic elegance of sunscreen lotions and creams, improving user compliance.
  • Moisturizing Properties: Sun exposure can be drying to the skin. The humectant properties of silk protein help to counteract this, providing essential hydration during sun exposure.
  • Enhanced Stability: Some studies suggest that silk derivatives can help stabilize UV filters, potentially improving the overall efficacy and longevity of the sun protection.
