Used in textile sizing to improve yarn strength and reduce breakage during weaving. Enhances adhesion of fibers and provides smooth surface for processing. Also applied in paper coating to improve printability and surface strength. Widely used as a water-soluble film in packaging, especially for detergents and agrochemicals, due to its biodegradability and ability to dissolve in water. Employed in emulsion polymerization as a stabilizer and protective colloid. Commonly used in adhesives, especially for paper and cardboard, because of its good bonding properties and water resistance after drying. Utilized in construction materials as a component in cement and plaster formulations to improve workability and water retention. Also found in medical and pharmaceutical applications, such as in eye drops for lubrication and in wound dressings due to its biocompatibility and film-forming ability.
