Sodium polyacrylate is the sodium salt of polyarylic acid. As a chemical polymer, it has various kinds of application in consumer products. It is capable of absorbing extremely high amount of water which can reach up to as much as 200 to 300 times its mass; therefore, it is used in agriculture industry and is infused in the soil of many plants to maintain the moisture of plant. It can be commonly used as a sequestering agent, or chelating agent in many detergents. It can also be used as a thickening agent to be used in diapers and hair gels because of its high capability of absorbing and holding water. Furthermore, it can be included in the coatings of sensitive electrical wiring to remove moisture in the wires.

People also use sodium polyacrylate as a water lock. As we all know, it is a sodium salt of polyacrylic acid. The polyacrylate sodium has [-CH₂-CH(CO₂Na)-]_n in it. The polyacrylic acid sodium salt is widely used in consumer products. This super-absorbent polymer can absorb 100 to 1,000 times its own mass in water.

The sodium polyacrylate is a cathode polyelectrolyte. It has a negatively charged carboxyl group in its main chain. Engineers neutralize polyacrylic acid to get this sodium salt. This sodium polyacrylate polymer is used widely in industry. In addition, there are other kinds of salt of polyacrylic acid. Like potassium, lithium, and ammonium.
