Frequent Uses

Buffering Agent
Widely used as a buffering agent in pharmaceuticals and chemical formulations. It is particularly effective in maintaining a stable pH in solutions, making it ideal for use in biological and biochemical research, where precise pH control is essential.

Water Treatment
To help control the pH of water systems. It is commonly added to water in both industrial and municipal applications to prevent corrosion and scale formation, ensuring water remains within a desired pH range.

Detergents and Cleaning Products
To enhance the cleaning efficiency of detergents. It helps to soften water by binding to calcium and magnesium ions, allowing the detergent to work more effectively in cleaning fabrics, dishes, and other surfaces.

Laboratory Reagent
In the preparation of buffer solutions for biochemical and biological assays. It is also employed in the preparation of standard solutions for titrations and other analytical methods, where it provides a consistent pH environment.

Food Additive
Particularly in the production of processed foods. It acts as a stabiliser, emulsifier, and buffering agent, helping to maintain the desired texture, consistency, and shelf-life of foods such as cheese, baked goods, and beverages.

Cosmetic Formulations
Used to regulate the pH of formulations, ensuring that the products are skin-friendly and stable. It is commonly found in products such as shampoos, lotions, and creams.

Pharmaceutical Applications
As a stabiliser for active ingredients. It is also used in intravenous solutions, where it helps to balance the pH and prevent the degradation of sensitive compounds, ensuring the safety and effectiveness of the medication
