PEG300 | CAS No. 25322-68-3

Q: What is PEG300 (CAS: 25322-68-3)?

PEG300, or polyethylene glycol 300 (CAS: 25322-68-3), is a water-soluble polymer commonly used in various industries. It has a molecular weight of approximately 300 and appears as a white, waxy solid. PEG300 is non-toxic, non-reactive, and has low viscosity, making it versatile for applications requiring lubrication, solubilization, or emulsification. Its chemical structure is based on repeating ethylene oxide units, offering stability and compatibility with biological systems.

Q: What are the main uses of PEG300 (CAS: 25322-68-3)?

PEG300 (CAS: 25322-68-3) is widely used in pharmaceuticals as a laxative, tablet binder, and drug delivery excipient. In industry, it serves as a lubricant, surfactant, and coating agent. Food applications include its use as a stabilizer and emulsifier in products like ice cream and candies. In research, it is employed in analytical techniques and as a model compound for polymer studies. Its versatility stems from its chemical inertness and solubility properties.

Q: Is PEG300 (CAS: 25322-68-3) safe?

PEG300 (CAS: 25322-68-3) is generally considered safe when used within recommended concentrations. It is non-toxic, non-irritating, and approved by regulatory bodies like the FDA for pharmaceutical and food applications. However, high doses may cause gastrointestinal discomfort. Proper handling, such as wearing gloves and avoiding inhalation, is advised. Safety standards ensure its use in cosmetics and industrial products is low-risk, though skin contact should be minimized in prolonged exposure scenarios.

Q: How should PEG300 (CAS: 25322-68-3) be stored?

PEG300 (CAS: 25322-68-3) should be stored in a sealed, airtight container in a cool (below 25°C), dry, and dark environment to maintain stability. It is not hygroscopic but should be protected from moisture and contaminants. Avoid exposure to extreme temperatures or direct sunlight. When stored properly, PEG300 retains its chemical properties for extended periods, ensuring consistent performance in applications like pharmaceuticals and cosmetics.
