Glucuronolactone
What is Glucuronolactone?
Glucuronolactone is a cyclic compound formed from glucuronic acid, a substance naturally produced in the human body during glucose metabolism. It appears as a white, crystalline powder and serves primarily in skincare formulations as a multifunctional ingredient in moisturizers, serums, and protective creams. In products, it works by drawing water molecules to the skin's surface layers, enhancing hydration levels while contributing to a lightweight film that guards against dehydration and minor environmental stressors. This dual action stems from its chemical structure, which allows it to bind moisture effectively and interact with skin lipids to promote barrier integrity. Commonly incorporated at low levels, it integrates seamlessly into various textures without altering product stability or sensory feel.
