Butylene Glycol

Butylene Glycol is a small organic alcohol that serves as one of the most versatile multifunctional ingredients in cosmetic formulations. Its unique molecular structure allows it to function simultaneously as a humectant that binds moisture to skin, a solvent that enhances the penetration and stability of other actives, and a texture modifier that creates lightweight, non-greasy formulations. Formulators favor it over propylene glycol for its superior skin feel, lower tackiness, and excellent ability to solubilize both hydrophilic and lipophilic ingredients while maintaining product stability across varying temperatures.
