PEG and related polymers (PEG phospholipid constructs) are often sonicated when used in biomedical applications. However, as reported by Murali et al., PEG is very sensitive to sonolytic degradation and PEG degradation products can be toxic to mammalian cells. See more Polyethylene glycol is a polyether compound derived from petroleum with many applications, from industrial manufacturing to medicine. PEG is also known as polyethylene oxide (PEO) or polyoxyethylene … See more PEG is considered biologically inert and safe by the FDA. However, a growing body of evidence shows the existence of a detectable level of anti-PEG antibodies in approximately 72% of the population, never treated with PEGylated drugs, … See more The production of polyethylene glycol was first reported in 1859. Both A. V. Lourenço and Charles Adolphe Wurtz independently isolated products that were polyethylene glycols. … See more • Oregon State University informational paper on using PEG as a wood stabilizer See more Medical uses • Pharmaceutical-grade PEG is used as an excipient in many pharmaceutical products, in oral, topical, and parenteral dosage forms. • PEG is the basis of a number of laxatives (as MiraLax, RestoraLAX, etc.). See more PEG, PEO, and POE refer to an oligomer or polymer of ethylene oxide. The three names are chemically synonymous, but historically PEG is preferred in the biomedical field, whereas PEO is more prevalent in the field of polymer chemistry.
