Hydrolyzed Xylan
What is Hydrolyzed Xylan?
Hydrolyzed xylan is a derivative of xylan, a natural hemicellulose polysaccharide composed mainly of beta-1,4-linked xylose units, sourced from plant cell walls such as those in birch wood or other hardwoods. Through hydrolysis, the long chains are broken into smaller, more soluble fragments. In cosmetics, it belongs to the skin conditioning category, commonly appearing in moisturizers, creams, and serums. It works by forming a lightweight film on the skin's surface, which helps lock in moisture and prevents water loss. This action supports the skin's natural barrier, promoting a smoother texture and improved flexibility without greasiness. Its humectant properties draw hydration from the environment, making it suitable for daily skincare routines focused on hydration maintenance.
