Poly(ethylene glycol), commonly known as PEG, is a versatile polymer characterized by its average molecular weight of approximately 8,000. This crystalline powder is widely recognized for its solubility in water and biocompatibility, making it an essential ingredient in various industries. PEG is utilized in pharmaceuticals as a drug delivery agent, enhancing the solubility and stability of active compounds. Its unique properties allow for the formulation of hydrophilic coatings, which are crucial in medical devices and implants, promoting biocompatibility and reducing friction. Additionally, PEG serves as a humectant in cosmetics and personal care products, providing moisture retention and improving skin feel.

In the food industry, PEG is used as a food additive and stabilizer, contributing to the texture and consistency of various products. Its ability to form gels and emulsions makes it valuable in the formulation of creams and ointments. Researchers also leverage PEG in biochemical applications, such as protein purification and enzyme stabilization, due to its non-toxic nature. With its wide-ranging applications and benefits, Poly(ethylene glycol) stands out as a critical compound for professionals seeking reliable solutions in their respective fields.
