Silk Fibroin Powder is widely used in the cosmetics industry and currently represents its primary application area. With ongoing technological advancements, however, its applications have expanded into diversified fields such as biomedicine and nutraceuticals. As a natural silk fibroin powder, it offers unique biocompatibility and functional properties, giving it strong market potential across multiple high value-added sectors.
What Is Silk Fibroin Powder?
Silk fibroin powder is a powdered natural macromolecular protein extracted from silkworm silk. It is produced through processes including degumming, dissolution, dialysis, and freeze-drying. Rich in 18 amino acids, high-purity silk fibroin powder exhibits excellent biocompatibility, biodegradability, and good water solubility. It maintains a stable molecular structure and is easy to store and transport under ambient conditions, making it an ideal raw material for a wide range of functional products.
Applications of Silk Fibroin Powder in Cosmetics
The cosmetics industry is the main application field for silk fibroin powder for skincare products. Its hydrophilic functional groups make it an effective natural moisturizing agent, capable of absorbing or releasing moisture in response to changes in skin temperature and humidity, thereby supporting skin barrier maintenance. In addition, its crystalline structure can reflect and absorb ultraviolet radiation, providing a synergistic effect when formulated with sunscreen agents.
It also demonstrates good oil-binding properties, making it suitable for cosmetics designed for oily skin. In color cosmetics, it helps reduce excessive shine and improves color softness and uniformity. As a result, silk fibroin powder applications in color and skincare cosmetics include premium products such as creams, serums, sunscreens, foundations, and blushes.
Application of Silk Fibroin Powder in Other Fields
Beyond cosmetics, silk fibroin powder for biomedical applications has important uses in tissue engineering scaffolds, controlled drug delivery systems, and wound dressings. It provides a favorable microenvironment for cell adhesion and proliferation, supporting tissue regeneration and wound healing.
In the nutraceutical sector, due to its amino acid richness and high bioavailability, silk fibroin powder in nutraceuticals is incorporated into products such as collagen beverages and beauty gummies, serving as a functional ingredient in oral beauty formulations.
