Sodium Hydroxide 25% Technical Grade: Versatility in Application

Sodium Hydroxide, commonly known as caustic soda or lye, in a 25% solution, is a widely used chemical in various industrial processes. The Technical Grade of this product signifies its suitability for general industrial use, where ultra-high purity is not a critical requirement.

Chemical and Physical Properties

At a 25% concentration, Sodium Hydroxide is a colorless liquid. It maintains the basic properties of NaOH, being a strong alkali with high reactivity, particularly when it comes to acids and organic substances.

Concentration and Efficacy

The 25% solution is less aggressive than higher concentrations, making it safer to handle while still effective for many industrial applications. It remains highly soluble in water and can absorb moisture from the air.

Application and Usage

This concentration is frequently used in applications where a lower pH adjustment is needed, and in processes that require a milder but still effective alkaline environment.

Industrial Applications

The versatility of Sodium Hydroxide 25% Technical Grade makes it valuable in a broad spectrum of industries.

Manufacturing and Cleaning

It’s utilized in the manufacturing of paper, textiles, and detergents. In cleaning agents, it serves as an effective degreaser and is used in drain cleaners due to its ability to dissolve fats and proteins.

Water Treatment

In water treatment facilities, it is used to adjust pH levels and remove heavy metals from water through precipitation.

Handling and Storage

Sodium Hydroxide, even at 25%, is a caustic substance and should be handled with care.

Safety Precautions

Appropriate personal protective equipment such as gloves, safety goggles, and protective clothing should be worn. Handling should be done in well-ventilated areas to avoid inhaling fumes.

Storage Guidelines

Store in a cool, dry place, away from acids, organic materials, and metal powders. Containers should be tightly closed to prevent the absorption of moisture from the air and contamination.


Sodium Hydroxide 25% Technical Grade is an essential chemical in a variety of industrial and manufacturing processes. Its moderate concentration allows for effective use while minimizing risks associated with handling and storage, making it a practical choice in many settings.
