Description

Disodium Octylphosphonate is an organophosphorus compound widely utilized as a high-performance chelating agent and scale inhibitor. Its primary value lies in its exceptional ability to sequester di- and trivalent metal ions, preventing precipitation and scaling in complex aqueous systems. This product is essential for industrial water treatment, detergent formulations, and as a key intermediate in specialty chemical synthesis for the textile and personal care industries.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems by chelating calcium, magnesium, and iron ions.
• Detergent & Cleaning Formulations: Serves as a superior builder and sequestrant in liquid and powder detergents, enhancing cleaning efficiency by inactivating water hardness ions.
• Textile Processing: Used as a peroxide stabilizer and metal ion control agent in bleaching and dyeing baths to ensure consistent color and fabric quality.
• Personal Care Products: Functions as a chelating agent in shampoos, soaps, and cosmetic formulations to improve stability and shelf life.
• Pulp & Paper Manufacturing: Applied in bleaching processes to deactivate transition metal catalysts that degrade cellulose, improving pulp brightness.
• Oilfield Chemicals: Utilized in scale squeeze treatments and as a component in drilling fluids to control mineral scale deposition in wells and pipelines.
• Industrial Cleaners: A key ingredient in acid-based and alkaline cleaners for metal surface treatment and equipment cleaning.
• Chemical Synthesis: Employed as a versatile phosphonate intermediate for producing more complex phosphonic acid derivatives and functional materials.

Quality Control

Our Disodium Octylphosphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, pH, and heavy metal content are provided to guarantee supply consistency and reliability for your critical processes.

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 opening to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
