Diethylene Glycol Monooctadecyl Ether（Cat No.:M078431）is a nonionic surfactant composed of a hydrophilic diethylene glycol head and a hydrophobic octadecyl (C18) alkyl chain. This amphiphilic structure makes it useful in emulsification, solubilization, and dispersion processes across cosmetic, pharmaceutical, and industrial formulations. It enhances stability in oil-in-water or water-in-oil systems and improves the delivery of active ingredients in creams, lotions, and drug carriers. Its compatibility with a wide pH range and low toxicity profile makes it suitable for sensitive formulations requiring mild, non-ionic emulsifying performance.
