Trisodium Citrate Dihydrate is widely used in the pharmaceutical industry as a multifunctional excipient. One of its primary roles is pH regulation in liquid formulations such as infusions, injections, and ophthalmic solutions. As part of citrate buffer systems, it helps maintain a stable pH, which is crucial for the stability of active ingredients and for ensuring patient comfort. In addition, it acts as a chelating agent by binding multivalent metal ions like calcium and iron, thereby preventing unwanted precipitation or interactions with other formulation components. Another important application is its use as an anticoagulant in blood preservation. By binding calcium ions, trisodium citrate inhibits blood clotting and enables the safe storage of blood products over extended periods.
In the food and beverage industry, Trisodium Citrate Dihydrate (E331 (iii)) is valued as a versatile, multifunctional additive. It is commonly used as an acidity regulator in soft drinks, jams, dairy products, and desserts to help manufacturers control and stabilize the pH of their products. It is commonly used in processed cheese production where Trisodium Citrate acts as an emulsifying salt, ensuring a smooth, uniform blend of fat and water for consistent texture and meltability. Trisodium Citrate also enhances flavors, improving the overall sensory experience of the final product. Moreover, in sport beverages it serves as an electrolyte contributing to mineral balance and hydration. Its high solubility and food-grade quality meet the strict standards required for use in modern food manufacturing.
Trisodium Citrate 2-Hydrate (Lohtragon® B09) for construction chemicals effectively delays setting times in cement and gypsum systems. This allows for longer processing windows, better control during application, and improved surface finishes — without sacrificing final strength.
In metal finishing,Lohtragon® B09 enhances plating quality by improving conductivity, stabilizing pH, and reducing precipitation. This results in uniform coatings, longer bath life, and less energy use.
As a water softener and pH regulator, Trisodium Citrate Dihydrate improves detergent performance in home care products. It boosts cleaning efficiency and formulation stability.
Lohtragon® B09 supports complex chemical reactions by regulating metal ion activity and maintaining stable pH levels. It improves process control, yields, and catalyst performance.
