Hydrolyzed Corn Starch
What is Hydrolyzed Corn Starch?
Hydrolyzed corn starch originates from corn (Zea mays) kernels, where natural starch undergoes hydrolysis—a process breaking large molecules into smaller, soluble fragments like oligosaccharides. This makes it highly water-compatible for cosmetic use in lotions, creams, cleansers, and powders. Primarily functioning as a humectant, it draws atmospheric moisture into the skin's outer layer, supporting barrier function and hydration. It also serves as a thickener, stabilizer, and mild exfoliant in formulations, creating a silky, non-greasy feel. Its absorbent qualities help control oil in powders, while film-forming ability enhances product evenness. Commonly in natural and gentle products, it offers a renewable, plant-based alternative to synthetic hydrators, aiding overall skin comfort without residue.
