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.

    Applications Poly(ethylene Glycol) molecules of an average molecular mass of 2000. Poly(ethylene Glycol) is used in various applications from industrial chemistry to biological chemistry. Recent research has shown PEG maintains the ability to aid the spinal cord injury recovery process, helping the nerve impulse conduction process in animals. In rats, it has been shown to aid in the repair of severed sciatic axons, helping with nerve damage recovery. It is industrially produced as a lubricating substance for various surfaces to reduce friction. PEG is also used in the preparation of vesicle transport systems in with application towards diagnostic procedures or drug delivery methods.
