Butylene Glycol is a versatile and multifunctional glycol widely used in personal care and household chemical formulations. As a high-efficiency humectant and coupling agent, butylene glycol provides reliable hydration and texture enhancement while improving the solubility and stability of active ingredients. Its balanced hydrophilic properties make it particularly valuable in serums, toners, and clear gel formulations, where it helps maintain product clarity and performance.
