Potassium Carbonate Anhydrous
Excipient (pharmacologically inactive substance)
What is it?
Potassium carbonate anhydrous, K2CO3 anyydrous, appears as a white powder or as colorless solid crystal that is void of water and has a salty taste. Also known as potash or pearl ash, it may be used in pharmaceutical laboratories as a drying agent. It also used in fire extinguishers, to make soap, to make glass, and to soften water.
All carbonate salts are on the FDA generally regarded as safe list. There is no evidence in the available information on calcium carbonate, potassium carbonate, potassium bicarbonate, sodium carbonate, sodium bicarbonate, or sodium sesquicarbonate that demonstrates or suggests reasonable grounds to suspect a hazard to the public when used at normal levels that are now current or that might reasonably be expected in the future.
