    Sodium Polyacrylate

    sodium prop-2-enoate

    Sodium Polyacrylate

    What is it?

    A polymer found frequently in daily life. Sodium polyacrylate is the absorbent material found in baby diapers, artificial decorative snow, and detergents. They polymer structure is made up of one molecule of oxygen, one molecule of sodium oxide, a carbon base, and three hydrogen molecules.

    More Information

    Sodium polyacrylate is commonly used as a sequestering agent, or chelating agent, in many detergents. It has the ability to bind hard-water elements, such as magnesium, calcium, iron and zinc, to make the detergents work more effectively. Chelating agents neutralize the presence of heavy metals that may be found in water, dirt and other substances that can be found in your laundry, making the detergent more effective in cleaning and neutralizing odors in your clothes.

    Sodium polyacrylate is primarily used as a thickening agent because of its unique ability to absorb and hold onto water molecules, making it ideal for use in diapers and hair gels. It is also used in industrial processes to dissolve soaps by absorbing water molecules. Thickening agents, like sodium polyacrylate, increase the viscosity of water-based compounds, which increases their stability. In diapers, sodium polyacrylate will absorb the water molecules found in urine, increasing the amount of liquid the diaper can hold while at the same time reducing the risk of diaper rash by promoting a dry environment.
