CAS 9004-74-4: Polyethylene glycol monomethyl ether

Description: Polyethylene glycol monomethyl ether (PEG-ME), with the CAS number 9004-74-4, is a non-ionic surfactant and polymer that is widely used in various applications, including pharmaceuticals, cosmetics, and industrial processes. It is characterized by its hydrophilic nature due to the presence of polyethylene glycol (PEG) chains, which enhances its solubility in water and compatibility with other substances. PEG-ME typically exhibits low toxicity and is considered safe for use in many formulations. Its molecular structure includes a methyl ether group, which contributes to its unique properties, such as improved stability and reduced viscosity compared to other PEG derivatives. The substance is often utilized as a solvent, emulsifier, or thickening agent, and it can also enhance the bioavailability of drugs in pharmaceutical applications. Additionally, PEG-ME is known for its ability to form films and improve the texture of products, making it valuable in cosmetic formulations. Overall, its versatility and favorable characteristics make PEG-ME a widely used compound in various industries.
