General information

Tripotassium citrate monohydrate is the common tribasic potassium salt of citric acid, also known as potassium citrate. It is produced by complete neutralisation of citric acid with a high purity potassium source and subsequent crystallisation.

Tripotassium citrate is used in foods, beverages, and technical applications as buffering, sequestering or emulsifying agent. It usually replaces trisodium citrate whenever a low sodium content is desired. In pharmaceuticals it is used as potassium source and as active ingredient to treat urinary duct stones. When added to oral care products, tripotassium citrate is the active ingredient to reduce the sensitivity of the teeth.

Tripotassium citrate occurs as transparent crystals or a white, granular powder. It is an odourless 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 contrary 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.

Being a leading producer of tripotassium citrate, Jungbunzlauer is able to provide a very promising natural alternative flame retardant for solid wood. The food-approved substance is safe and easy in handling. Furthermore, tripotassium Citrate is one of the few fully biodegradable and non-toxic flame retardants.
