Properties: Trisodium citrate dihydrate is the tribasic salt of citric acid. Produced by complete neutralization of high purity sodium-sourced citric acid followed by crystallization. Found as white, granular crystals or white crystalline powder. Odorless substance with pleasant salty taste. Freely soluble in water and practically insoluble in ethanol, efflorescing in moist air. Trisodium citrate dihydrate is a non-toxic, low reactivity neutral salt. Chemically stable when stored normally under ambient conditions. Completely biodegradable and can be disposed of with regular waste and sewage according to local regulations.

Most Important Functions: Trisodium citrate dihydrate is widely used in foods, beverages and various technical applications, mainly as a buffering agent, sequestering and emulsifying agent, acidity regulator and in pharmaceuticals for preparing serum and injectable solutions. It also has anhydrous form, which finds more interesting application areas due to its properties.

Food and Beverages: pH control, acidity regulator with citric acid, complexes trace metal ions, complexes calcium ions in cheese, modifies or enhances taste, gives flexibility to cheese slices, gives uniform melting properties, slows down gelation action in pectin gels, stabilizes whipped cream, helps flavor development in cheese, provides color stabilization in meat, prevents phosphate buildup formation on meat surface.

Pharmaceuticals: Complexes calcium, pH buffer, maintains stability of active ingredient, reduces astringency, acts as anti-plaque and anticoagulant agent, acts as alkalizer for blood and urine.

Personal Care: pH buffer, enhances effect of methyl parabens.

Cleaners and Detergents: Replaces phosphates, reacts with other chemicals, rapidly biodegrades.

Industrial Applications: Provides bright layer in alkaline baths, acts as sequestering agent in metal plating, as component of dyeing plate emulsions in photochemicals, pH adjustment and metal complexes in photochemicals, acts as blowing agent and nucleating agent in polymer and plastic production, acts as pigment dispersant in pigment slurries, provides lower viscosity and improves stability in pigment slurries.
