Used as a solvent and humectant in cosmetics and personal care products, especially in formulations requiring moisture retention and improved texture. Commonly found in skin creams, lotions, and hair conditioners due to its ability to attract and retain water. Also serves as a coupling agent in cleaning products to enhance solubility of ingredients. Occasionally used in industrial applications as a mild surfactant or in specialty detergents where low volatility and high hydrophilicity are needed.
