Polyethylene Glycol PEG-200 (CAS No.: 25322-68-3), chemical name α-Hydro-ω-hydroxypoly(oxy-1,2-ethanediyl), is a typical non-ionic surfactant produced by Guoli Chemical. Its molecular structure consists of ethoxy chains, appearing as a colorless, transparent, viscous liquid. With excellent chemical inertness and versatility, it is widely used as a high-performance auxiliary material and processing aid across various industrial fields.
PEG-200 possesses excellent emulsification and solubilization capabilities, effectively reducing interfacial tension between different liquid phases and promoting the stable dissolution and uniform mixing of poorly soluble substances. Additionally, it exhibits outstanding wetting and dispersing functions, significantly improving the wetting state of solid particles in liquid media, preventing sedimentation and flocculation, and enhancing formulation uniformity. In terms of chemical stability, PEG-200 demonstrates resistance to acids, alkalis, and hard water, remaining unreactive with most chemicals under a wide range of operating conditions, ensuring reliable system performance.
This product has good compatibility with anionic, cationic, and other non-ionic surfactants. It possesses high toxicological safety, is mild and non-irritating, and is easily biodegradable. The acute oral toxicity (rat) LD50 is greater than 2000 mg/kg, classified as low toxicity; skin irritation index is 0 to 0.5, indicating no irritation or very mild irritation; no skin sensitization or genotoxicity.
