About this ingredient

Butylene glycol is a lightweight humectant and solvent derived from petroleum or renewable sources like corn. It attracts moisture to the skin, improving hydration and skin feel while reducing stickiness, and also functions as a preservative booster and viscosity modifier in cosmetic formulations. It is well-tolerated across most skin types and commonly used in skincare and makeup products.
