PEG5000

PEG5000 refers to polyethylene glycol with an average molecular weight of approximately 5000 Daltons. Polyethylene glycol is a polymer derived from ethylene oxide, characterized by repeating oxyethylene groups. The number "5000" in PEG5000 denotes its average molecular weight, which influences its physical properties such as viscosity and solubility. PEG5000 is a water-soluble, non-toxic, and biocompatible substance, making it suitable for various applications.

In the pharmaceutical industry, PEG5000 is utilized as an excipient in drug formulations, enhancing drug solubility, stability, and controlled release. It can also be employed as a laxative, drawing water into the intestines to promote bowel movements. Its use in cosmetics and personal care products includes acting as a humectant, moisturizer, and emulsifier in creams, lotions, and shampoos. Additionally, PEG5000 finds application in laboratory research, such as in cell fusion techniques and as a component of protein purification methods. Due to its inert nature, it is often chosen for its low reactivity and good compatibility with biological systems.
