Octaethylene glycol monohexadecyl ether is a nonionic surfactant frequently utilized in various industrial and research contexts. As a member of the polyethylene glycol (PEG) ether family, it features a hydrophilic head and a lipophilic tail, making it suitable for emulsions, detergents, and solubilizers. It is particularly valuable in membrane protein research for dissolving and stabilizing proteins for structural analysis techniques. Additionally, Octaethylene glycol monohexadecyl ether can interact with and penetrate cell membranes, offering potential applications in drug delivery and other medical fields.
