What is Glycereth-26?

Glycereth-26 is a hydrophilic polyether compound created by reacting glycerin with 26 molecules of ethylene oxide, resulting in a clear, viscous liquid. This ethoxylated derivative enhances water solubility and stability in cosmetic products like creams, lotions, serums, and cleansers. Primarily functioning as a humectant, it binds atmospheric moisture to the skin's outer layer, promoting hydration. As a solvent, it helps integrate active components and oils into water-based systems for even distribution. Its viscosity-controlling properties allow formulators to achieve ideal product thickness, improving spreadability and feel during application. Commonly included in daily skincare and hair care, it contributes to lightweight, non-greasy hydration without residue, making it versatile across formulations.
