Hydrolyzed Silk
What is Hydrolyzed Silk?
Hydrolyzed silk originates from fibroin, the natural protein in silkworm cocoons, broken down via hydrolysis into smaller, soluble peptides for cosmetic use. This process enhances its compatibility in formulations like shampoos, conditioners, moisturizers, and serums. In products, it functions by forming a lightweight film on hair shafts and skin surfaces, which reduces friction for better manageability and imparts a silky texture. As a humectant, it draws moisture to the surface, supporting hydration without greasiness. Its antistatic properties minimize flyaways, while protein content aids in surface smoothing, making it suitable for both hair care and skin conditioning applications across rinse-off and leave-on items.
