1. Introduction

EDTA-4NA is a chemical compound derived from ethylenediamine, formaldehyde, and sodium cyanide. Its chemical formula is C10H12N2Na4O8. This compound is highly soluble in water due to the presence of tetrasodium salt, making it easy to integrate into various aqueous systems. The chelating properties of EDTA-4NA enable it to form stable complexes with metal ions, which find applications in different fields.

2. Understanding Chelation

Chelation is a chemical process in which a chelating agent binds to metal ions, forming a complex that prevents the metal ions from participating in chemical reactions or causing unwanted effects. EDTA-4NA has the unique ability to chelate a wide range of metal ions, including calcium, magnesium, iron, copper, and zinc. This property makes it an effective tool for controlling and manipulating metal ions in various applications.

3. The Properties of EDTA-4NA

EDTA-4NA possesses several important properties that contribute to its versatility as a chelating agent. It is highly water-soluble, allowing for easy incorporation into aqueous solutions. Additionally, EDTA-4NA is stable over a wide pH range, ensuring its effectiveness in both acidic and alkaline environments. These properties make it an ideal choice for diverse applications.

4. Applications in Various Industries

Food and Beverage Industry

In the food and beverage industry, EDTA-4NA is commonly used as a food preservative and an antioxidant. It helps to prevent oxidation and maintain the color, flavor, and nutritional value of food and beverage products. EDTA-4NA is also utilized to sequester metal ions that can cause rancidity or affect the stability of certain food formulations.

Cosmetics and Personal Care

EDTA-4NA finds application in the cosmetics and personal care industry as a stabilizer and preservative. It helps to enhance the stability and shelf life of cosmetic products, such as creams, lotions, and shampoos. By chelating metal ions, EDTA-4NA inhibits the degradation of active ingredients, ensuring product effectiveness over time.

Agriculture and Horticulture

EDTA-4NA plays a vital role in agriculture and horticulture. It is used as a micronutrient fertilizer additive to enhance the availability of essential metals, such as iron, zinc, and copper, to plants. EDTA-4NA facilitates the absorption of these metals, promoting plant growth and improving crop yield.

Industrial Processes

EDTA-4NA is extensively used in various industrial processes. It serves as a complexing agent in metal plating, metal cleaning, and metal surface treatment applications. The chelating properties of EDTA-4NA aid in the removal of unwanted metal ions and scale, resulting in cleaner and more efficient industrial operations.

5. Environmental Considerations

While EDTA-4NA offers numerous benefits, it is essential to consider its environmental impact. The stable complexes formed by EDTA-4NA with metal ions can potentially affect wastewater treatment processes. Therefore, responsible handling and disposal practices should be adopted to minimize any adverse environmental effects.

6. Safety Precautions and Handling

When working with EDTA-4NA, it is important to follow safety precautions. Ensure proper ventilation in the working area to avoid inhalation of fumes or dust particles. Always wear appropriate personal protective equipment (PPE), such as gloves and goggles, when handling this compound. Store EDTA-4NA in a cool, dry place, away from incompatible substances.


  1. Is EDTA-4NA safe for consumption in food and beverages?

    EDTA-4NA is not intended for direct consumption in food and beverages. It is primarily used as a food preservative and should be handled and used according to regulatory guidelines.

  2. Can EDTA-4NA be used as a standalone fertilizer in agriculture?

    EDTA-4NA is typically used as a micronutrient fertilizer additive. It helps to enhance the availability of essential metals to plants but is not used as a standalone fertilizer.

  3. Does EDTA-4NA have any adverse effects on human health?

    When used according to guidelines and industry standards, EDTA-4NA is considered safe for its intended applications. However, it is important to handle and use it responsibly, following proper safety precautions.

  4. Where can I find EDTA-4NA for industrial use?

    EDTA-4NA can be sourced from chemical suppliers or manufacturers specializing in chelating agents for industrial applications.

  5. Can EDTA-4NA be used in organic farming?

    The use of EDTA-4NA in organic farming is generally not permitted since it is a synthetic compound. Organic farming practices prioritize the use of natural and organic inputs.


EDTA-4NA, as a versatile chelating agent, offers a wide range of applications across various industries. Its ability to form stable complexes with metal ions makes it valuable in the food and beverage industry, cosmetics and personal care products, agriculture, and industrial processes. However, it is important to consider its environmental impact and handle it responsibly. By understanding the properties and applications of EDTA-4NA, industries can harness its potential while prioritizing safety and sustainability.
