CAS 25322-68-3

Polyethylene glycol

Description:

Polyethylene glycol (PEG), with the CAS number 25322-68-3, is a versatile polymer known for its hydrophilic properties and biocompatibility. It is composed of repeating units of ethylene oxide, resulting in a structure that can vary in molecular weight, which influences its physical and chemical characteristics. PEG is typically a colorless, odorless, and viscous liquid or a waxy solid, depending on its molecular weight. It is soluble in water and many organic solvents, making it useful in a wide range of applications, including pharmaceuticals, cosmetics, and food products. PEG serves as a lubricant, humectant, and emulsifier, and is often used in drug formulations to enhance solubility and bioavailability. Additionally, its non-toxic nature and ability to form hydrogels make it valuable in biomedical applications, such as drug delivery systems and tissue engineering. However, the specific properties of PEG can vary significantly with its molecular weight and formulation, which must be considered when selecting it for particular applications.
