Polyethylene Glycol 200 (PEG-200), chemically named α-hydro-ω-hydroxypoly(oxy-1,2-ethanediyl), is a high-quality nonionic surfactant produced by Guoli Chemical. This product is polymerized from ethylene oxide and water, with a molecular weight of approximately 200, and appears as a colorless transparent viscous liquid at room temperature.
PEG-200 possesses excellent chemical inertness and versatility. Its molecular structure contains ether bonds and terminal hydroxyl groups, giving it both hydrophilicity and certain lipophilicity, effectively reducing the interfacial tension between different liquid phases and promoting the stable dissolution and uniform mixing of poorly soluble substances. At the same time, this product is resistant to acids, alkalis, and hard water, and does not react with most chemicals over a wide range of operating conditions, ensuring the reliability of system performance.
As one of the core products of Guoli Chemical, PEG-200 has good compatibility with anionic, cationic, and other nonionic surfactants. It also has high toxicological safety—acute oral toxicity (rat) LD50 is greater than 2000 mg/kg, classified as low toxicity. It causes no or only very slight irritation to the skin, is readily biodegradable, and has no bioaccumulation potential, making it an environmentally friendly industrial auxiliary material choice.
