What is water balls sodium polyacrylate and chemistry


Sodium polyacrylate, also known as waterlock, is a sodium salt of polyacrylic acid with the chemical formula [-CH2-CH(CO2Na)-]n and broad application in consumer products. This superabsorbent polymer has the ability to absorb as much as 200 to 300 times its mass in water. Sodium polyacrylate is an anionic polyelectrolyte with negatively charged carboxylic groups in the main chain. While sodium neutralized polyacrylic acids are the most common form used in industry, there are also other salts available including potassium, lithium and ammonium.

The origins of superabsorbent polymer chemistry trace back to the early 1960s when the U.S. Department of Agriculture developed the first super absorbent polymer materials.

Applications

Sodium polyacrylate Is Sodium Polyacrylate Safe SOCO

Sodium polyacrylate and other derivatives of polyacrylic acid have a wide variety of commercial and industrial uses. These include:

  • Sequestering agents in detergent products, such as dish detergent and laundry detergent. By binding hard water elements such as calcium and magnesium, the surfactants in detergents work more efficiently.
  • Thickening agent for products such as hair styling gel
  • Coatings
  • Artificial snow for motion picture and stage productions
  • Disposable diapers, including the Maximum Absorbency Garment used by NASA astronauts
  • Potting soil for containerized plants
  • Refreezable gel packs
  • Bath time recreational gel (such as Gellibaff or Squishybaff)
  • Personal lubricant
  • Copolymer versions are used in agriculture and other specialty absorbent applications.
