Description

Pentasodium Dtpa CAS NO 140-01-2 is the pentasodium salt of diethylenetriaminepentaacetic acid, a powerful and versatile chelating agent. Its primary value lies in its exceptional ability to sequester a wide range of di- and trivalent metal ions, even under challenging conditions of high temperature and pH. This makes it a critical component for industries requiring superior scale inhibition, water treatment, and stabilization processes. Key sectors that rely on this product include industrial cleaning, pulp & paper processing, textile manufacturing, and personal care formulations.

Application

• Industrial Cleaning & Boiler Treatment: Acts as a superior sequestrant for calcium, magnesium, and iron ions to prevent scale formation in boilers, cooling towers, and industrial cleaning formulations.
• Pulp & Paper Bleaching: Stabilizes hydrogen peroxide and other bleaching agents by chelating transition metal ions (like Mn, Fe, Cu) that catalyze their decomposition, improving bleaching efficiency and pulp brightness.
• Textile Processing: Used in scouring, bleaching, and dyeing baths to complex with metal ions present in water or fabric, preventing unwanted color shifts and improving dye fastness and fabric quality.
• Personal Care Products: Functions as a chelating agent in shampoos, soaps, and lotions to enhance stability, preserve clarity, and improve the efficacy of preservatives by inactivating metal contaminants.
• Agricultural Chemistry: Incorporated into micronutrient fertilizers and agrochemicals to improve the bioavailability of essential metal ions like iron, zinc, and manganese for plant uptake.
• Water Treatment: Effective in controlling hardness and heavy metal ions in various water treatment applications, including industrial wastewater.
• Detergent Formulations: Enhances the performance of detergents and soaps by softening water and preventing the redeposition of soil and stains on fabrics.
• Photographic & Imaging: Used in developer and fixer solutions to control the concentration of metal ions that can affect image quality and process stability.

Quality Control

Our Pentasodium Dtpa is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, chelation value, and physical properties. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing key parameters such as assay, pH, and heavy metal content. Our production adheres to relevant industry standards, and we can support compliance documentation for various global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking and reduced efficacy.
