Tripotassium citrate occurs as transparent crystals or a white, granular powder. It is an odorless substance with a cooling, salty taste. It is slightly deliquescent when exposed to moist air, freely soluble in water, and almost insoluble in ethanol (96%). In contrast to other potassium salts, it is less bitter and thus can be used at higher concentration levels.
Tripotassium citrate is a non-toxic, slightly alkaline salt with low reactivity. It is chemically stable if stored at ambient temperatures. In its monohydrate form, it is very hygroscopic and must be protected from exposure to humidity. Care must be taken not to expose tripotassium citrate monohydrate to high pressure during transport and storage, as this may result in caking.
