Polyethylene glycol monomethyl ether

Description:
Polyethylene glycol monomethyl ether (PEG-ME), with the CAS number 5702-16-9, 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 properties, which stem from the polyethylene glycol (PEG) backbone, and its hydrophobic methyl ether group, which enhances its solubility in organic solvents. PEG-ME typically exhibits low toxicity and is biocompatible, making it suitable for use in drug formulations and as a stabilizer in emulsions. The molecular weight of PEG-ME can vary, influencing its physical properties such as viscosity and solubility. It is often utilized as a solvent, dispersant, or thickening agent, and can also serve as a polymeric surfactant in various formulations. Additionally, PEG-ME is known for its ability to improve the stability and bioavailability of active ingredients in pharmaceutical and cosmetic products. Its versatility and favorable safety profile contribute to its widespread use across multiple industries.
