Description

2,3-Dihydroxypropyl (Dihydrogen Phosphate), Trisodium Salt is a water-soluble, organophosphate salt with versatile chelating and sequestering properties. This compound is valued for its ability to bind metal ions, making it a critical component in formulations requiring stabilization and control of trace metals. It is primarily needed by manufacturers in the personal care, industrial cleaning, and water treatment industries for its efficacy as a stabilizer and complexing agent.

Application

• Personal Care & Cosmetics: Acts as a stabilizing and chelating agent in creams, lotions, and shampoos to enhance product shelf-life and performance.
• Industrial & Institutional (I&I) Cleaners: Used in detergent and cleaner formulations to sequester hardness ions (e.g., calcium, magnesium) and improve cleaning efficiency.
• Water Treatment: Employed as a scale inhibitor and dispersant in cooling water and boiler water systems.
• Textile Processing: Serves as a chelant in dyeing and finishing baths to prevent metal-ion interference and ensure color consistency.
• Agricultural Formulations: Can be used as a stabilizer or compatibility agent in certain pesticide and fertilizer solutions.
• Laboratory & Research: Utilized as a biochemical reagent or buffer component in various life science applications.

Quality Control

Our 2,3-Dihydroxypropyl (Dihydrogen Phosphate), Trisodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting these results 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 controlled 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 degradation.
