Water-soluble synthetic polymers are a class of polymers that dissolve in water to form solutions or gels. These materials have gained significant attention due to their wide range of applications in industries such as pharmaceuticals, food, cosmetics, textiles, and environmental science. Their solubility in water makes them useful for applications that require biocompatibility, biodegradability, and easy removal without harmful residues. While many water-soluble polymers are biodegradable, some persist in the environment. Research is ongoing to develop fully degradable polymers that reduce microplastic pollution and enhance sustainability.
