CrimeaPRESS reports:
Let’s start by deciphering this complex abbreviation. EDTA is ethylenediaminetetraacetic acid, but its tetrasodium salt form is more commonly used in production. It works as a chelating agent, or simply put, it helps to “bind” metals and prevent them from negatively affecting products or processes. If you work in the cosmetics, food or pharmaceutical industries, you’ve probably seen it on the list of ingredients. But why is it needed there? This is what we will talk about.
Where is EDTA (4Na) salt used?
1. Cosmetics industry
Tetrasodium salt EDTA — a real find for cosmetics manufacturers. Its task is to prevent the destruction of the product due to the presence of metals in the composition. For example, water used in cosmetics may contain small amounts of iron, magnesium or calcium ions. These metals can cause the components to oxidize, which will spoil the product — it will change color, smell or even texture.
Here’s why EDTA is so important:
- It binds metal ions, preventing them from oxidizing the formula.
- Increases product stability.
- Extends shelf life.

2. Food industry
Here EDTA also plays an important role, but now its task is to prevent products from spoiling. In the food industry, it is often added to canned food, sauces, mayonnaise and margarine. It prevents oxidation, which can lead to unpleasant odors or changes in taste.
- Extends shelf life products.
- Preserves their taste and aroma.
- Protects against rancidity of fats and oils.
3. Pharmaceuticals
In the pharmaceutical industry, tetrasodium salt EDTA is used to stabilize drugs, prevent the decomposition of active substances and improve their bioavailability. That is, it helps the medicine maintain its effectiveness throughout its shelf life.
4. Cleaning products and household chemicals
In purifiers, EDTA helps soften water, making detergents more effective. It binds calcium and magnesium ions, which give water hardness, which allows soap and other detergents to foam better and be more effective. This is important for products that must cope with hard water.
Sample list of products containing tetrasodium EDTA:
- Liquid detergents
- Fabric softeners
- Dishwashing detergents
- Cleaning sprays for the home
Advantages of using tetrasodium salt EDTA in production
1. Increasing product stability
One of the main advantages of EDTA is its ability to improve product stability. It is important to understand that manufacturers need to ensure product quality for a long time. EDTA helps prevent degradation of active ingredients and maintain texture, flavor and color throughout shelf life. This is especially true for cosmetics and pharmaceuticals.
2. Increased shelf life
EDTA also extends the shelf life of products, which is very important for the cosmetics and food industries. Many foods can oxidize quickly when exposed to metals, resulting in deterioration in quality. The use of EDTA solves this problem.
3. Protection from hard water
In household chemicals, tetrasodium salt EDTA helps detergents be more effective, especially in hard water conditions. This reduces the consumption of detergents and increases their effectiveness.
How to properly use tetrasodium EDTA?
Although EDTA is very beneficial, it is important to dose it correctly. In most cases, it is added in minimal quantities, from 0.05% to 0.2% of the total volume of the product. Do not overdo it, as too much may affect the texture of the product or its effect on the skin. You should always follow dosage recommendations from raw material manufacturers.
Important points when using EDTA:
- Follow the dosage.
- Include EDTA in formulas only after consultation with technologists.
- Monitor product changes after adding EDTA (especially during the testing phase).

How to store tetrasodium salt EDTA?
Like any chemical ingredient, EDTA requires proper storage. It is best to keep it in a cool, dry place, away from direct sunlight. It is also important to avoid moisture as this may affect its effectiveness.
Basic storage rules:
- Store in a tightly closed container.
- Avoid contact with moisture.
- Store at temperatures between 10 and 25°C.
Conclusion
Tetrasodium salt EDTA is not just a complex chemical compound, but a real assistant in the production of a wide variety of products. It protects formulas from degradation, extends shelf life and makes products of higher quality. Whether you’re in the cosmetics, food, or pharmaceutical industries, EDTA may be the solution you’ve been looking for to improve your products.
