Abstract
A novel zinc compound, an alkali metal or ammonium zinc citrate, is prepared for use in mouthwash compositions to provide mouthwashes with less astringency without loss of anti-odor properties, improved water solubility of the zinc compound and improved chemical compatibility when ionic fluoride salts are employed in compositions along with the zinc compound.
