Poly(ethylene glycol) (PEG) with an average molecular weight of approximately 3,000,000 is a high-molecular-weight polymer supplied as a white powder. It is primarily utilized in industrial applications as a lubricant, thickener, dispersant, and surfactant in formulations for coatings, adhesives, inks, and polymer composites to enhance flexibility, processability, and physical properties. In materials science, it serves as a compatibilizer in blends and a component in hydrogels for non-pharmaceutical uses such as tissue scaffolds due to its biocompatibility. High MW PEG is also employed in water treatment as a flocculant for precipitation and clarification processes, and in personal care products as a conditioning and moisturizing agent in creams and lotions. Note: This grade is not typically used in direct pharmaceutical or food applications due to its high molecular weight.
