Citric Acid Monohydrate

White crystalline powder with a sour taste.

Citric acid monohydrate is widely used as a flavoring and preservative in the food and beverage industry, as a chelating agent in cosmetics, and for pharmaceutical preparations. Its biodegradable nature makes it favored in environmentally friendly cleaning products.

Energy Sector

In the energy sector, particularly in oil field cementing, citric acid monohydrate is utilized to control the setting time of cement slurries. It acts as a retarder, allowing for deeper well penetration by delaying the cement setting process. This adjustment ensures the integrity of the cement sheath, preventing gas migration and enhancing zonal isolation. Its application is critical in maintaining wellbore stability and optimizing cementing operations in challenging environments.

Water Treatment

In water treatment processes, citric acid monohydrate plays a crucial role as a natural chelating agent and pH adjuster. It effectively binds with metal ions, facilitating their removal from the water, thereby softening hard water. This action helps in preventing scale formation and corrosion in pipes and boilers, extending the lifespan of water treatment infrastructure. Moreover, its biodegradability makes it an environmentally friendly choice for treating wastewater, ensuring that treated water can be safely released or reused with minimal environmental impact.


Citric acid monohydrate is utilized in agriculture to enhance soil properties and as a component in biodegradable pesticides. It adjusts the pH level of soil, improving nutrient availability and absorption by plants. This can lead to healthier crop growth and increased yield. Additionally, its acidic nature makes it effective as a natural pesticide and fungicide, helping to control a variety of pests and diseases without harming the environment. Its use in agriculture supports sustainable farming practices by reducing reliance on chemical pesticides and improving soil health.
