Hydrolyzed Soy Flour
What is Hydrolyzed Soy Flour?
Hydrolyzed soy flour originates from soybeans (Glycine max), where the flour undergoes hydrolysis—a process breaking down complex proteins into smaller peptides and amino acids using water, enzymes, or acids. This results in a water-soluble ingredient commonly used in skincare formulations like creams, lotions, and masks within the skin conditioning category. It functions by attracting moisture to the skin's surface (humectant action), forming a lightweight film to lock in hydration, and interacting with skin proteins to enhance suppleness. Its mild nature suits both rinse-off and leave-on products, providing a non-greasy feel while supporting overall skin comfort without heavy occlusion.
