Description

Phosphinic Acid, Octyl-, Monosodium Salt is an organophosphorus compound that serves as a highly effective and versatile specialty chemical. This product is valued for its unique properties as a stabilizer and chelating agent, offering solutions for material durability and process control. It is primarily utilized by manufacturers in the polymer, detergent, and water treatment industries seeking to enhance product performance and longevity.

Application

• Polymer Stabilizer: Acts as a secondary stabilizer and metal deactivator in polyolefins (e.g., PP, PE) to prevent thermal and oxidative degradation during processing and end-use.
• Detergent Builder: Functions as a sequestering agent in industrial and institutional cleaning formulations to control water hardness ions and improve surfactant efficiency.
• Water Treatment Chemical: Used in cooling water and boiler water systems as a scale and corrosion inhibitor, particularly for controlling calcium and other metal ions.
• Paper & Pulp Industry: Employed in bleaching processes and as a chelant to control metal ions that can catalyze decomposition of bleaching agents and cause discoloration.
• Textile Auxiliary: Serves as a stabilizer in peroxide bleaching baths for textiles, preventing catalytic decomposition of the peroxide by trace metals.
• Personal Care: Can be used in select personal care formulations as a chelating agent to enhance the stability and shelf-life of products.

Quality Control

Our Phosphinic Acid, Octyl-, Monosodium Salt is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, moisture content, and metal impurities are available upon request to support your quality assurance protocols.

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); keep the container tightly sealed to prevent absorption of atmospheric moisture which may affect product quality.
