Description

Calcium Trisodium Diethylenetriaminepentaacetate Hydrate is a high-purity, water-soluble chelating agent of the polyaminocarboxylate family. This compound is valued for its exceptional ability to sequester di- and trivalent metal ions, forming highly stable complexes even under challenging conditions. It is essential for industries requiring precise control over metal ion activity, such as pharmaceuticals, personal care, and industrial cleaning formulations.

Application

• Pharmaceutical Manufacturing: Used as a stabilizing agent in injectable solutions, eye drops, and other formulations to chelate trace metal impurities that can catalyze degradation.
• Personal Care & Cosmetics: Acts as a chelator in shampoos, creams, and lotions to enhance product stability by inactivating metal ions from water or raw materials.
• Industrial Cleaning & Detergents: Incorporated into hard surface cleaners and detergent builders to improve cleaning efficiency by controlling water hardness ions.
• Agricultural Chemicals: Serves as a micronutrient carrier and stabilizer in fertilizer and pesticide formulations to prevent precipitation.
• Pulp & Paper Processing: Used in bleaching processes to deactivate transition metal ions that can degrade cellulose fibers.
• Textile Treatment: Applied in dyeing and finishing baths to sequester metal ions that can cause shade variation or fabric damage.
• Water Treatment: Functions as a scale inhibitor and dispersant in boiler and cooling water systems.
• Analytical Chemistry: Employed as a standard or masking agent in complexometric titrations and other analytical methods.

Quality Control

Our Calcium Trisodium DTPA Hydrate is manufactured under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metals, and loss on drying are provided with every shipment. We can supply material compliant with relevant standards for pharmaceutical (USP/EP), food (FCC), and industrial applications.

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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
