Product Description:

Poly(oxy-1,2-ethanediyl), ж┴-hydro-ж╪-hydroxy-, commonly known as polyethylene glycol (PEG), is a synthetic, hydrophilic polyether compound with the general formula H(OCH_CH_)_OH. It is available in a wide range of molecular weights, from liquids (e.g., PEG 400) to waxy solids (e.g., PEG 4000), determined by the number of repeating ethylene oxide units. As a versatile excipient, PEG is widely used in pharmaceuticals as a solvent, co-solvent, and base for ointments and suppositories, enhancing drug solubility and bioavailability. In cosmetics, it functions as a humectant, emollient, and skin-conditioning agent, improving product texture and moisture retention. Its low toxicity, high water solubility, and biocompatibility also make it a key component in industrial applications, such as a lubricant in metalworking and a plasticizer in polymers.
