Description

Diethylenetriaminepentaacetic Acid Calcium Trisodium Salt is a highly effective chelating agent and sequestrant, known for its strong affinity for polyvalent metal ions. This property makes it a critical component for controlling metal-catalyzed degradation and ensuring product stability across various demanding industrial processes. It is essential for manufacturers in the personal care, detergent, pulp & paper, and water treatment industries who require reliable metal ion control to maintain product quality and performance.

Application

• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to inactivate water hardness ions (calcium, magnesium) and heavy metals, enhancing surfactant efficiency and preventing scale deposition.
• Personal Care & Cosmetics: Used as a chelating agent in shampoos, soaps, and creams to stabilize formulations by binding trace metals that can cause rancidity, discoloration, or degradation of active ingredients.
• Pulp & Paper Industry: Employed in bleaching processes to sequester metal ions like iron and manganese, which can catalyze the decomposition of bleaching agents and damage cellulose fibers.
• Industrial Water Treatment: Functions as a scale and corrosion inhibitor in cooling water systems, boilers, and reverse osmosis membranes by controlling scale-forming cations.
• Textile Processing: Improves the quality of dyeing and bleaching operations by chelating metal impurities in process water and on fabrics, resulting in brighter, more consistent colors.
• Agriculture: Incorporated into certain agrochemical formulations and micronutrient fertilizers to enhance the bioavailability and stability of essential metal nutrients.

Quality Control

Our Diethylenetriaminepentaacetic Acid Calcium Trisodium Salt is manufactured under a stringent 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, heavy metal content, and loss on drying 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). This product 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.
