Description

Tetrasodium Dicarboxymethyl Aspartate is a high-performance, biodegradable chelating agent and sequestrant derived from aspartic acid. This compound matters for industries seeking effective, environmentally friendly alternatives to traditional phosphates and EDTA, offering excellent metal ion control and stability. It is primarily needed by formulators in the cleaning, personal care, and water treatment sectors who require a powerful yet sustainable chelant for their products.

Application

• Primary chelant in heavy-duty liquid detergents and automatic dishwashing formulations to control water hardness ions.
• Stabilizer and sequestrant in industrial and institutional cleaning products to enhance surfactant performance and prevent scale.
• Key ingredient in personal care products such as shampoos and liquid soaps for improved foam stability and clarity.
• Scale and corrosion inhibitor in industrial water treatment and cooling tower applications.
• Peroxide stabilizer and metal deactivator in pulp & paper processing and textile bleaching.
• Additive in agricultural formulations to chelate micronutrients and improve product stability.

Quality Control

Our Tetrasodium Dicarboxymethyl Aspartate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, chelation value, and physical properties. 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial use to prevent caking and degradation from atmospheric moisture.
