Polyacrylic acid (PAA) is a high molecular weight polymer composed of acrylic monomers, which has various uses. Here are some of the main application areas:

  1. Sanitary products: PAA is widely used in disposable diapers due to its super absorbent properties, which can absorb water several times its weight.
  2. Personal care products: Derivatives of PAA are used as thickeners or stabilizers in products such as hand creams, toothpaste, shaving cream, latex thickeners, and hand cleaners.
  3. Water treatment: Polyacrylic acid is used as a flocculant in water treatment to help purify water quality.
  4. Pharmaceutical field: As a component of artificial tears, it is used to treat dry eye syndrome. The protonated form of PAA is responsible for mucosal adhesion at acidic pH, forming hydrogen bonds with the - COOH group of mucin through its - COOH group.
  5. Agriculture: PAA, as a soil amendment, helps improve soil structure.
  6. Industrial applications: PAA is used to improve viscosity and stability in industrial products such as coatings, inks, adhesives, etc.
  7. Environmental remediation: PAA is used in wastewater treatment to capture heavy metals and remove dyes.
  8. Drug delivery system: The pH sensitivity of PAA makes it very useful in drug delivery systems, especially in tumor therapy, utilizing the acidic environment of tumor cells.
  9. Cosmetics and skincare products: PAA is also used in cosmetics and skincare products due to its thickening and moisturizing properties.
  10. Ophthalmic drug delivery: PAA is used in ophthalmic drug delivery systems, such as as as a component of artificial tears or as a sustained-release carrier in ophthalmic drug delivery systems.
    These applications demonstrate the wide range of uses of PAA as a multifunctional material in different fields.To understand the parameters of polyacrylic acid, please refer to the following website:https://www.kairuiwater.com/paa.htm
