E332 Antioxidant

E332 is rapidly absorbed when given by mouth, and is excreted in the urine. Since it is an alkaline salt, it is effective in reducing the pain and frequency of urination when these are caused by highly acidic urine. It is used for this purpose in dogs and cats, but is chiefly employed as a non-irritating diuretic.

E332 is an effective way to treat/manage gout and arrhythmia,[medical citation needed] if the patient is hypokalemic.

E332 is widely used to treat urinary calculi (kidney stones), and is often used by patients with cystinuria.[medical citation needed] A study of 500 patients with recurrent stones found that it reduced the frequency of stones from 2 per year to 0.5 per year.

E332  is also used as an alkalizing agent in the treatment of mild urinary tract infections, such as cystitis.

It is also used in many soft drinks as a buffering agent.

Frequently used in an aqueous solution with other potassium salts, it is a wet chemical fire suppressant that is particularly useful against kitchen fires. Its alkaline pH encourages saponification to insulate the fuel from oxidizing air, and the endothermic dehydration reaction absorbs heat energy to reduce temperatures
