Polyethylene oxide (PEO) is a versatile water-soluble polymer widely used across various industries due to its biocompatibility, adjustable viscosity, and excellent solubility in water.

• Pharmaceutical Industry: Acts as a binder, lubricant, and film-forming agent in tablet manufacturing. It controls the release of active ingredients in extended-release formulations and is used in hydrogel production for medical devices, wound dressings, and contact lenses.
• Cosmetics Industry: Serves as a thickening agent and stabilizer in creams, lotions, and gels, enhancing texture and consistency.
• Water Treatment: Employed as a flocculant to aggregate fine particles, facilitating their removal from water.
• Adhesives and Coatings: Improves viscosity and adhesion properties.
• Textile Industry: Used as a sizing agent to protect fibers during weaving, increasing softness and reducing friction.
• Paper Production: Aids in sedimentation and improves paper quality as a retention and drainage agent.
• Agriculture: Incorporated into slow-release fertilizers to control nutrient delivery.

Additionally, PEO is utilized in scientific research and engineering for developing hydrogels and composite materials, making it a valuable component in industrial and consumer products.
