What Is Dtpa-5Na Diethylenetriaminepentaacetic Acid Pentasodium Salt?

DTPA-5Na, the diethylenetriaminepentaacetic acid pentasodium salt, it is a high-performance chelating agent widely used in agriculture, industry, personal care, and water treatment. It is a water-soluble, strong metal ion binder that can sequester both divalent and trivalent metal ions effectively, including calcium, magnesium, iron, copper, lead, and others. Compared to EDTA, DTPA-5Na provides greater chelating strength, especially at higher pH levels, and is ideal for formulations requiring more stable metal complexes.

Our lifeworth is professional supplier and manufacturer for DTPA series products. We supply 40% 50% pentasodium diethylene triaminepentaacetic acid pentasodium salt DTPA-5Na solution, which is a yellow or light yellow transparent liquid in appearance and soluble in water. The total annual output is more than 30,000 Ton. Secondly, we also supply DTPA, with a total annual output of more than 10,000 tons. The products comply with international standards. Currently, the products have been exported to more than 60 countries around the world, including the United Kingdom, Canada, and France. The quality of the products is well recognized by customers.

Key Features and Benefits

Strong chelating capacity: Binds with a wide range of metal ions, including Fe³⁺, Cu²⁺, Zn²⁺, Mn²⁺, Pb²⁺, and Ca²⁺.

Effective at high pH: Unlike EDTA, DTPA-5Na maintains chelating performance even in alkaline conditions.

Improves product stability: Prevents metal-catalyzed oxidation, discoloration, and degradation.

Broad compatibility: Can be used in diverse applications such as agriculture, cosmetics, detergents, and more.

Low toxicity and environmentally friendly when used appropriately.

Applications

Agriculture and Micronutrient Fertilizers
DTPA-5Na is commonly used to manufacture chelated micronutrient fertilizers. It serves as the base for chelates like:

Fe-DTPA (Iron chelate)

Zn-DTPA (Zinc chelate)

Cu-DTPA (Copper chelate)

These products are used in foliar sprays, fertigation, and hydroponic systems to correct micronutrient deficiencies and improve crop growth, especially in neutral to alkaline soils.

Water Treatment
In industrial and municipal water systems, DTPA-5Na is used to:

Prevent scale formation and corrosion

Bind heavy metals in boiler and cooling systems

Improve detergent efficiency and reduce hardness

Personal Care and Cosmetics
DTPA-5Na is a common ingredient in:

Shampoos

Soaps

Lotions

Hair dyes

It stabilizes formulations by binding trace metal ions that could otherwise cause discoloration, rancidity, or reduced efficacy.

Cleaning Products and Detergents
In household and industrial cleaning agents, DTPA-5Na enhances cleaning performance by:

Softening hard water

Preventing soap scum

Improving the performance of surfactants

Pharmaceutical and Medical Uses
In clinical settings, DTPA and its salts are used for:

Heavy metal detoxification (e.g., lead and plutonium)

As a component of MRI contrast agents (e.g., Gd-DTPA)

Laboratory and Analytical Chemistry
DTPA-5Na is used in:

Metal titrations and analysis

Buffer solutions

Chelate formation studies
