General description

Polyethylene glycol (PEG) is a versatile and non-ionic polymer commonly used in a range of industrial and pharmaceutical applications due to its low toxicity, hydrophobic nature, and semicrystalline structure. It is made up of CH2-CH2O repeating units and its ability to exist in both monomer and aqueous phases at high temperatures makes it valuable for a range of research applications.

Biochem/physiol Actions

Polyethylene glycols (PEGs) or macrogols are broadly used as additives in cosmetics and pharmaceuticals. Addition of this hydrophilic polymer blocks and reverses some types of surfactant inactivation in vitro. PEG can be used as a macroinitiator, stabilizer, or dispersant in the field of emulsion polymerization with the help of its derivatives or modifications.
