Description

Disodium 2,2'-[2-Hydroxypropane-1,3-Diylbis(Oxy)]Diethyl Dihydrogen Diphosphate is a specialized organophosphate compound with a unique molecular structure designed for effective chelation and stabilization. This chemical matters for its ability to bind metal ions, preventing unwanted precipitation and degradation in complex formulations, thereby enhancing product performance and shelf-life. It is primarily needed by manufacturers in the personal care, industrial cleaning, and water treatment industries seeking advanced sequestering agents.

Application

• Personal Care & Cosmetics: Acts as a highly effective chelating agent in shampoos, conditioners, and skin creams to stabilize formulations by sequestering metal ions (e.g., Ca²⁺, Mg²⁺) that can cause rancidity and discoloration.
• Industrial & Institutional (I&I) Cleaners: Used in liquid soaps, hard surface cleaners, and detergent formulations to improve cleaning efficiency by inactivating water hardness ions and preventing scale formation.
• Water Treatment: Employed as a scale and corrosion inhibitor in cooling water systems and boiler water treatment to control mineral deposition.
• Textile Processing: Serves as a stabilizing agent in bleaching and dyeing baths to protect fibers and ensure consistent color results by complexing interfering metal ions.
• Pulp & Paper Industry: Utilized in bleaching processes to chelate transition metals that catalyze the decomposition of bleaching agents like hydrogen peroxide, improving process efficiency.
• Agricultural Formulations: Incorporated into certain pesticide and fertilizer solutions to enhance stability and compatibility by sequestering metal contaminants.

Quality Control

Our Disodium 2,2'-[2-Hydroxypropane-1,3-Diylbis(Oxy)]Diethyl Dihydrogen Diphosphate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity and performance. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with each shipment to guarantee compliance with your specifications.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial use to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
