Polyethylene glycol PEG-200 is a non-ionic surfactant. With its excellent chemical inertness, emulsifying and solubilizing properties, and low toxicity and safety, it is used as a high-performance auxiliary and processing aid in numerous industrial fields. Its applications range from daily consumer products to precision industrial manufacturing, making it a typical "multifunctional platform" chemical raw material.
In the daily chemical industry, PEG-200 mainly serves as a moisturizer, lubricant, and viscosity regulator, and is widely used in product formulations such as shampoos, body washes, creams, and toothpaste. In the pharmaceutical field, it acts as an ointment base and drug co-solvent, effectively improving the bioavailability of active ingredients. In agriculture, PEG-200 is used as an emulsifying dispersant for pesticides, helping to evenly disperse the active ingredients and improve application efficiency.
In industrial manufacturing, the role of PEG-200 is equally critical. It is a basic component of mold release agents in the rubber and plastics industry and a core ingredient of heat transfer fluids in metalworking and casting industries. In addition, as an important synthetic intermediate, PEG-200 participates in esterification, etherification, and other chemical reactions, and is used to produce specialty surfactants, polyurethane resins, and plasticizers, making it one of the important raw materials for fine chemical synthesis.

Summary of specific application processes across industries:
Although PEG-200 is a low-toxicity product, it is still recommended to wear safety goggles and protective gloves during operation and use in well-ventilated areas. The product is hygroscopic; keep the container sealed during storage and store in a cool, dry place. The recommended storage temperature is 15°C to 30°C. Avoid co-storage with incompatible substances such as strong acids and strong oxidizers. If accidentally splashed into eyes, rinse immediately with plenty of water for at least 15 minutes; if irritation persists, seek medical attention.
