Inulin
What is Inulin?
Inulin is a naturally occurring polysaccharide composed of fructose units, primarily extracted from the roots of chicory (Cichorium intybus), a plant in the Asteraceae family. Chemically, it belongs to the fructan group, forming long chains that make it highly water-soluble. In cosmetics, it appears in moisturizers, cleansers, serums, and hair care formulations. As a humectant, it draws moisture from the environment into the skin's outer layer and hair shaft, enhancing hydration without greasiness. It also acts as a skin conditioner by forming a protective film that smooths surfaces and boosts flexibility. Additionally, its prebiotic properties nourish beneficial skin microbes, potentially supporting barrier function in products targeting hydration and conditioning.
