Anhydroxylitol
What is Anhydroxylitol?
Anhydroxylitol is a cyclic polyol created by dehydrating xylitol, a natural sugar alcohol sourced from plant-derived xylose found in birch wood or corn cobs. This bio-based ingredient belongs to the family of anhydrosugars and is widely used in moisturizers, serums, creams, and hair care products. As a humectant, it functions by forming hydrogen bonds with water molecules, pulling moisture from the environment and lower skin layers into the stratum corneum to maintain hydration levels. Its skin conditioning properties arise from its ability to interact with skin proteins and lipids, promoting flexibility and a smooth texture. With a structure that allows moderate penetration, it supports the skin's natural moisture barrier without heaviness. Often featured in formulations targeting dehydration, anhydroxylitol offers a sustainable, plant-inspired alternative to traditional humectants in cosmetic science.
