Description

2-Propenoic Acid, 2-Hydroxy-, Homopolymer, Sodium Salt is a high-purity, water-soluble polymer derived from acrylic acid. This compound is valued for its exceptional thickening, suspending, and stabilizing properties in aqueous systems. It is a critical raw material for formulators and manufacturers in industries such as personal care, pharmaceuticals, and water treatment, where precise rheology control and product stability are paramount.

Application

• Personal Care & Cosmetics: Acts as a primary thickener, stabilizer, and film-forming agent in shampoos, shower gels, lotions, creams, and hair styling products.
• Pharmaceuticals: Used as a binder, disintegrant, and viscosity-modifying agent in tablet formulations, topical gels, and controlled-release drug delivery systems.
• Water Treatment: Functions as a scale inhibitor and dispersant in industrial water circuits, boiler water, and reverse osmosis systems.
• Paints & Coatings: Serves as a rheology modifier and thickener in latex paints, adhesives, and other water-based coating formulations to improve application properties.
• Textile & Paper Industries: Employed as a sizing agent, thickener for printing pastes, and retention aid in paper manufacturing processes.
• Detergents & Cleaners: Enhances the viscosity and stabilizes the suspension of active ingredients in liquid soaps and hard surface cleaners.

Quality Control

Our production of Sodium Polyacrylate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure consistent purity, viscosity, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, pH, residual monomers, and heavy metal content are available upon request. We support compliance with relevant frameworks including ISO 9001 and cGMP where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial opening to prevent caking and degradation due to atmospheric moisture.
