Used as a viscosity modifier and rheology control agent in aqueous systems, particularly in personal care formulations such as shampoos, conditioners, and lotions. Enhances thickening and stabilizes emulsions by interacting with surfactants and water molecules. Also serves as a multifunctional monomer in the synthesis of specialty polymers and hydrogels, where its hydroxyl groups allow for crosslinking. Exhibits humectant properties, contributing to moisture retention in cosmetic and dermatological products.
