Sodium tetraborate decahydrate, better known as borax, is a versatile raw material that has been used in the cleaning industry for many years. Thanks to its chemical properties, this substance is ideally suited for professional cleaning formulations as well as industrial applications.

In this article, you will learn how borax works, what advantages it offers, and why it is a staple in modern cleaning solutions.

What is Sodium Tetraborate (Borax)?

Sodium tetraborate decahydrate is an inorganic compound with the formula:

Na₂B₄O₇·10H₂O

It is a white, crystalline powder that is readily soluble in water. In solution, borax exhibits a slightly alkaline reaction, which is crucial for its cleaning action.

The substance is obtained from natural borate deposits and is then purified and crystallized to ensure consistent quality for industrial applications.

Chemical Properties and Cleaning Action

The effectiveness of borax is based on several properties that make it a valuable component of cleaning agents.

Alkaline Effect

Borax increases the pH of cleaning solutions, thereby supporting:

• the removal of fats and oils
• the breakdown of organic soils
• general cleaning efficiency

Complex Formation (Chelation Effect)

A key advantage is its ability to bind metal ions such as calcium and magnesium. This results in:

• hard water is "softened"
• limescale deposits are reduced
• cleaning performance remains constant

Buffering Effect

Borax stabilizes the pH of the solution and ensures:

• consistent cleaning performance
• better process control
• increased stability of formulations

Use in Cleaning Agents

Borax is used in many cleaning products – both in industrial and commercial settings.

Typical Applications:

• detergents and textile cleaning
• all-purpose cleaners
• industrial degreasers
• water treatment systems

Due to its properties, borax enhances the effectiveness of other ingredients, especially surfactants.

Benefits of sodium tetraborate

Versatile cleaning

Borax is effective against:

• grease and oil contamination
• organic residues
• mineral deposits

Efficiency in hard water

By binding calcium and magnesium, cleaning performance remains stable even under unfavorable water conditions.

Cost-effectiveness

Borax is a cost-effective raw material with high efficacy, making it particularly attractive for industrial applications.

Broad range of applications

In addition to cleaning agents, borax is also used in:

• glass and ceramics industry
• metal processing
• chemical production

Safety and handling (EU)

In the European Union, borax is subject to certain classifications and should only be used properly.

Important notes:

• may impair fertility (H360FD)
• avoid contact with eyes and skin
• use appropriate protective equipment

Storage

• store dry and tightly sealed
• protect from moisture
• store out of reach of unauthorized persons

Significance for industrial applications

Due to its combination of alkaline action, complex formation, and stability, borax is an important component of modern cleaning formulations.

It enables:

• more efficient processes
• better cleaning results
• stable product quality

Conclusion

Sodium tetraborate (borax) is a proven and versatile raw material in the cleaning industry. Its chemical properties make it an effective component of professional cleaning solutions.

When used correctly and in compliance with EU regulations, borax is a reliable and cost-effective solution for numerous industrial applications.
