Xylitol
What is Xylitol?
Xylitol is a naturally occurring sugar alcohol, or polyol, found in fruits, vegetables, and hardwood like birch trees. In cosmetics, it serves primarily in skincare, oral care, and lip products. Chemically, it is a five-carbon sugar alcohol produced via hydrogenation of xylose from plant sources. As a humectant, it binds water molecules to the skin's surface layers, promoting moisture retention. It functions as a skin conditioner by enhancing barrier flexibility and smoothness, while its mild sweetness makes it ideal for flavoring in toothpastes and balms. Unlike some sugars, it does not promote bacterial growth, supporting its use in formulations for daily hydration without stickiness. Common in moisturizers, serums, and cleansers at various concentrations.
