Poly(ethylene oxide) is widely used in various industries due to its unique properties. In pharmaceuticals, it serves as a binder, lubricant, and film-forming agent in tablet formulations, ensuring controlled drug release. It is also utilized in ophthalmic solutions and as a thickening agent in topical gels. In the cosmetics industry, it acts as a stabilizer and viscosity modifier in creams, lotions, and shampoos.

In industrial applications, it is employed as a flocculant in water treatment processes to remove suspended particles. Additionally, it is used in the manufacturing of adhesives, coatings, and lubricants due to its water-soluble and film-forming characteristics. It is also applied in paper production to enhance strength and durability. In research, poly(ethylene oxide) is a key component in hydrogel preparation for biomedical applications, such as tissue engineering and drug delivery systems. Its versatility and biocompatibility make it a valuable material across multiple fields.
