Polyethylene oxide is widely used in various industries due to its unique properties. In the pharmaceutical sector, it serves as a binder, lubricant, and film-forming agent in tablet formulations, enhancing drug delivery and stability. It is also employed in ophthalmic solutions and as a base for topical gels due to its water solubility and biocompatibility.

In the personal care industry, it is a key ingredient in cosmetics, shampoos, and lotions, providing viscosity control and smooth texture. Its ability to form films makes it useful in hair styling products and skin moisturizers.

In industrial applications, polyethylene oxide is utilized as a thickener in water-based coatings, adhesives, and inks. It improves the flow and leveling properties of these products. Additionally, it is used in wastewater treatment as a flocculant, aiding in the aggregation and removal of suspended particles.

In the field of agriculture, it acts as a soil conditioner, improving water retention and reducing erosion. Its versatility and non-toxic nature make it a valuable component across multiple domains.
