Sodium polymethacrylate is a versatile superabsorbent polymer widely used across multiple industries. In personal care, it serves as a key ingredient in diapers, sanitary napkins, and adult incontinence products, absorbing and retaining large volumes of liquid for enhanced comfort and performance. It is also employed in cosmetics, such as creams, lotions, and facial cleansers, to provide smooth texture, improve moisture retention, and leave skin feeling soft and hydrated.

In pharmaceuticals, it acts as a viscosity modifier in gels and creams, aiding adhesion to the skin and enabling controlled release of active ingredients for improved therapeutic efficacy.

In agriculture, it functions as a soil conditioner to enhance water retention in arid soils, promoting plant growth, and as a component in seed coatings to maintain moisture and boost germination rates.

Additionally, in water treatment, it performs as a dispersant to inhibit scale and deposit formation in industrial systems. Its multifunctional properties make it invaluable in these sectors.
