Poly(acrylic acid), sodium salt, 20% soln. in water [MW ~ 225,000]

Poly(acrylic acid), sodium salt (PAA-Na) is a water-soluble polymer with carboxylate functionality, supplied as a 20% aqueous solution. PAA-Na is commonly used as a dispersant for mineral suspensions, a thickener for formulations, and a stabilizer in emulsions. Its sodium salt form offers improved solubility and pH stability, making it suitable for a wide range of aqueous formulations. It exhibits excellent water absorption, rheology modification, and dispersion properties, making it essential in industries such as:
Water Treatment: As a scale inhibitor and dispersant to prevent fouling in pipelines and boilers.
Detergents: As a polymer additive to improve soil dispersion and anti-redeposition properties.
Pharmaceuticals: As a viscosity modifier in gels and ointments.
Cosmetics: In personal care products as a thickener and stabilizer for emulsions.
