Sodium polyacrylate, also known as waterlock, is a sodium salt of polyacrylic acid with the chemical formula [−CH2−CH(CO2Na)−]n and has broad applications in consumer products. This super-absorbent polymer (SAP) has the ability to absorb 100 to 1000 times its mass in water. Sodium polyacrylate is an anionic polyelectrolyte with negatively charged carboxylic groups in the main chain. Sodium polyacrylate is a chemical polymer made up of chains of acrylate compounds. It contains sodium, which gives it the ability to absorb large amounts of water.
Sodium polyacrylate is also classified as an anionic polyelectrolyte. When dissolved in water, it forms a thick and transparent solution due to the ionic interactions of the molecules. Sodium polyacrylate has many favorable mechanical properties. Some of these advantages include good mechanical stability, high heat resistance, and strong hydration. It has been used as an additive for food products including bread, juice, and ice cream.

Industry Grade
Sodium polyacrylate is a polymer that soaks up 300 times its own weight in water. Its nickname is the Super Slurper. It is used in baby diapers to keep baby bottoms dry. It is also a more convenient way to provide water to animals during transportation. The water-soaked polymer crystals won’t spill, and animals can eat them to get water. Another common use is a soil substitute, which is what we will make in this experiment.
Sodium polyacrylate Application
(1) Nontoxic, Safety and Environment friendly: non-toxic and tasteless, no pollution to the plants, the soil, the groundwater, the flowers, the fruit trees, the reforestation, the soilless cultivation of plants refrigerated transportation and other field crops.
(2) Water Saving.
(3) Improve the soil structure.
(4) Long Validity.
(5) High absorbing speed.
(6) High utilization rate of water fertilizer.
(7) The root can not get putrefied when absorbing enough water.
(8) Function stability. Even though in the extreme dry region, the root will not decompose.
Water-soluble polymers are used in many industries, especially polyacrylates. Some applications include thickeners, flocculants, dispersants, and drag-reducing agents. Polyacrylates are also used as environmentally friendly adhesives or coatings.
In addition, sodium polyacrylate is used in paper diapers and Maximum Absorbency Garments as the absorbent material. It is also used in ice packs to convert the water used as the cooling agent into a gel, in order to reduce spillage in case the ice pack leaks. Sodium polyacrylate has also been studied for utilization in many applications such as nanofiltration of water to absorb water and concentrate the liquid with microbes.
Also, it is used for eco-engineering as a water-retaining agent in rocky slopes for increasing moisture availability in the soil. This can improve the water retention availability of the soil and infiltration capacity in sandy soil. Below is a table containing categories and lists of some products and applications that utilize sodium polyacrylate:
Sequestering Agents
Sodium polyacrylate is commonly used in detergents as a chelating agent. A chelating agent is used in detergents because it has the ability to neutralize heavy metals that can be found in dirt, water, and other substances that could be in clothes. The addition of sodium polyacrylate makes detergent more effective when cleaning clothes.
Thickening Agents
Since sodium polyacrylate can absorb and retain water molecules, it is used often in diapers, hair gels, and soaps. Sodium polyacrylate is considered a thickening agent because it increases the viscosity of water-based compounds. In diapers, sodium polyacrylate absorbs water found in the urine in order to increase the capacity to store liquid and to reduce rashes.
Coatings
Sodium polyacrylate can also be utilized as a coating for electrical wires in order to reduce the amount of moisture around wires. Water and moisture near wires can cause issues with transmitting electrical signals. This could cause potential fire hazards. Due to the effective absorption and swelling capacity of sodium polyacrylate, it can absorb water and prevent it from surrounding or infiltrating wires.
Agriculture
In the agricultural industry, sodium polyacrylate is used to help plants retain moisture in the soil. It can act as a water reservoir for plants and is commonly used by florists to keep flowers fresh. Furthermore, the use of sodium polyacrylate for growing domestic fruit and vegetables has been approved by the U.S. Department of Agriculture.
Removal of Metal Ions from the Environment
Studies have shown that sodium polyacrylate and other super-absorbent polymers or SAPs can be used to absorb and recover metal ions. Heavy metals are very harmful pollutants and can have detrimental effects on aquatic environments and human beings because of high toxicity, bioaccumulation, and non-degradability. Activities like mining and petroleum refining can produce these heavy metals which necessitate a simple and environmentally sustainable process to absorb these harmful metals to prevent disastrous results. Sodium polyacrylate can absorb solutions quickly by swelling porous structure networks to reduce mass-transfer resistance. Also, sodium polyacrylate is a low-cost, non-toxic, and biocompatible option for water purification to recover metal ions.
Drug Delivery Applications
Sodium polyacrylate can be used for microencapsulation to deliver substances like probiotics. The delivery of probiotics to the digestive system can be difficult because the viability of probiotics decreases sharply throughout the gastrointestinal tract due to strong acid conditions. Although Alginate (Alg) is the most extensively used native microcapsule matrix, combining Alg with sodium polyacrylate yields better results based on research comparing different encapsulation methods. Sodium polyacrylate is an oral safe food additive approved by the Food and Drug Administration (FDA) and has repeated carboxylate groups along its molecular chain. As a result, the acid buffering effect of sodium polyacrylate could be better than small molecular acid. Also, the binding capacity of sodium polyacrylate with calcium ions could be higher than Alg because of the high concentration of carboxylate groups and the increasingly flexible nature of the polymer chain.
