POLYETHYLENE GLYCOL (PEG 400) is a versatile polymer widely used in pharmaceutical formulations as a solvent, plasticizer, and excipient. Often present in surplus inventory, this chemical offers significant potential for cost recovery, freeing up valuable storage space, and reducing disposal fees. Its unique properties, including excellent solubility, low toxicity, and compatibility with active pharmaceutical ingredients, make it indispensable in the development of oral, topical, and parenteral medications. When companies have excess PEG 400, they not only deal with inventory overstock but also gain an opportunity to generate revenue by selling quality surplus materials to other manufacturers and distributors around the world.
