Brief Overview
Trisodium citrate anhydrous is an inorganic compound with the chemical formula Na3C6H5O7. It is commonly referred to as sodium citrate. It has a saline taste and a mildly tart flavor, which is known as “sour salt.” It is the natural tribasic salt of citric acid, and its IUPAC name is trisodium;2-hydroxypropane-1,2,3-tricarboxylate. The anhydrous form of trisodium citrate occurs as white, granular crystals or as a white, crystalline powder. It is completely soluble in water and practically insoluble in ethanol (96 %). It is a non-toxic, neutral salt with low reactivity. It is chemically stable if stored at ambient temperatures. Trisodium citrate anhydrous is fully biodegradable and can be disposed of with regular waste or sewage.
Manufacturing Process
Trisodium citrate anhydrous is produced through the dehydration of trisodium citrate dihydrate. The dehydration process removes water molecules without affecting the original crystal matrix. This leads to the formation of crystals with a porous matrix, allowing it to act as the carrier of organic/inorganic substances for applications such as perfumes.
