Description

Tetrasodium 2-(Dicarboxylatomethoxy)Propanedioate is a high-purity, water-soluble chelating agent and sequestrant. This compound is valued for its exceptional ability to bind and deactivate polyvalent metal ions, preventing unwanted precipitation and catalytic degradation. It is essential for industries requiring robust metal ion control and stabilization in aqueous systems, such as detergents, personal care, and industrial cleaning formulations.

Application

• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to enhance surfactant performance and prevent scale formation in hard water.
• Personal Care Products: Used in shampoos, liquid soaps, and creams as a stabilizer and chelating agent to protect product integrity.
• Industrial Water Treatment: Serves as a scale and corrosion inhibitor in cooling and boiler water systems.
• Textile Processing: Functions as a chelant in bleaching, dyeing, and finishing baths to improve process efficiency and fabric quality.
• Pulp & Paper Manufacturing: Enhances bleaching processes and controls metal ions that can degrade pulp or cause discoloration.
• Agricultural Chemicals: Used as a stabilizer and compatibility agent in certain pesticide and fertilizer formulations.

Quality Control

Our Tetrasodium 2-(Dicarboxylatomethoxy)Propanedioate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) documenting assay, heavy metal limits, and other critical parameters is available for each shipment 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). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption and caking.
