Used in the formulation of personal care products, it acts as a solubilizer and emulsifier, enhancing the stability and texture of creams, lotions, and other cosmetic items. In pharmaceuticals, it serves as a carrier or excipient, improving the solubility and bioavailability of active ingredients. Additionally, it is employed in the development of drug delivery systems, particularly in creating nanoparticles and micelles for targeted therapy. Its PEG (polyethylene glycol) chain provides water solubility and biocompatibility, making it suitable for biomedical applications. It is also utilized in research for surface modification and functionalization of materials.
