Tetrasodium EDTA

This is a white solid.

It mixes very well with water. It is used in hair and skin care. You might find it in soap. It can help clean old metal. It can remove rust from surfaces. It also helps clean engine parts. People have used it since 1954. It is a very useful tool for making things. It helps keep products working well.

Tetrasodium EDTA is a white solid.

It mixes very well with water. This substance is a salt. It is made from a chemical called ethylenediaminetetraacetic acid. People have used it since 1954. It acts as a chelating agent. This means it can grab onto other things.

Many products use this tool. You can find it in skin and hair care. It is also used in cosmetics. It helps clean many types of metal. It can remove rust and scale. This works on copper and brass. It also works on ferrous metal.

Some engine cleaners use it too. These cleaners use a 6% mix. In those mixes, it is the main part. It can also help clean engine coolant systems. A 1% mix in water has a pH of 11.3. This tells us how much it acts like a base. This substance is also called Dissolvine E-39. It is a salt of edetic acid.

Tetrasodium EDTA is a useful white solid.

It is a type of salt. This salt comes from a chemical called ethylenediaminetetraacetic acid. It dissolves very easily in water. Scientists call it a chelating agent. This means it can grab onto other things. It is a very important tool for many different jobs.

This substance works in a special way. It is made by a process called neutralization. This happens when ethylenediaminetetraacetic acid meets sodium hydroxide. This process creates the salt we call tetrasodium EDTA. Some samples are hydrated, which means they hold water. These are written as Na4EDTA.4H2O. If you mix a 1% solution in water, the pH is about 11.3. This number shows it acts like a base. When it is in neutral water, it partially turns into H2EDTA2-.

People have known about this substance since at least 1954. It is also known by the name Dissolvine E-39. It is a salt of edetic acid. Many companies use it in their work. One firm is Procter and Gamble. They hold 5% of the patents at the USPTO for this substance. This shows how much people use it.

This white solid helps clean many things. It is used in cosmetics and skin care. You might find it in hair care products too. It can also remove rust from metals. It cleans scale from copper and brass. It even works on ferrous metal surfaces. Some engine coolant system flushes use a 6% mix. In those cleaners, it is the main active ingredient.

Think about how a magnet works. A magnet grabs onto metal pieces. A chelating agent like tetrasodium EDTA does something similar. It grabs onto other parts in a liquid. This helps keep products stable or cleans surfaces. It is used as a preservative in many items. It is also known as an E-number additive. This makes it a common part of our world.

Tetrasodium EDTA is a specific type of chemical salt. It is used widely as a source of a chelating agent called EDTA4-. A chelating agent is a substance that can grab and hold onto other molecules. This salt appears as a white solid in its pure form. It is highly soluble, which means it dissolves very easily in water.

Because it is so useful in many industries, it is a common component in various products. It is also known by the name Dissolvine E-39. Scientists also classify it as a salt of edetic acid.

The creation of this salt involves a process called neutralization. This occurs when ethylenediaminetetraacetic acid reacts with four equivalents of sodium hydroxide. Sodium hydroxide is a strong base. This reaction transforms the acid into the salt we call tetrasodium EDTA. Commercial samples are often found in a hydrated state. This means the salt contains water molecules, such as Na4EDTA.4H2O. Interestingly, the anhydrous and hydrated forms produce solutions with the same properties. This remains true as long as the solutions maintain the same pH level.

When you look at how this substance behaves in water, the chemistry is quite specific. A 1% aqueous solution has a pH of approximately 11.3. This high number indicates that the solution is quite basic. If you dissolve the salt in neutral water, a chemical change occurs. The substance partially converts into H2EDTA2-. This change in structure is part of how the salt interacts with its environment. Understanding these shifts helps scientists use the substance correctly in different mixtures.

History shows that this substance has been known to researchers since at least 1954. Since then, it has become a major part of many industrial processes. One notable example of its importance is found in patent records. The firm Procter and Gamble is a major player in this field. They are the assignee on 5% of all patents at the USPTO that contain this substance. This high percentage shows how much specialized knowledge exists regarding its use.

Tetrasodium EDTA has many practical uses in everyday products. It is used most notably in the cosmetics industry. You can find it in various hair and skin care products. Beyond personal care, it serves a heavy-duty industrial purpose. It helps create products used to remove rust and corrosion. It can also remove scale from several types of metal. This includes copper, brass, and other surfaces. It is even effective on ferrous metal surfaces.

In some mechanical applications, the concentration of the substance is very specific. For example, it is used in engine coolant system flushes. In some of these flushes, tetrasodium EDTA is the main active ingredient. To achieve the right cleaning power, these products use a concentration of 6%. This allows the chelating agent to work effectively within the cooling system. By grabbing onto mineral buildup, it helps keep the engine parts clean.

Because of its many roles, tetrasodium EDTA is categorized in several ways. It is classified as an acetic acid derivative and a tertiary amine. It also serves as a preservative to help products stay stable. In the food and additive industry, it is known as an E-number additive. It can even be categorized as an antidote in certain scientific contexts. This wide range of categories shows how many different systems rely on its unique ability to bind with other substances.
