potassium bitartrate
butanedioic acid, 2,3-dihydroxy-, (R-(R*,R*))-, monopotassium salt (9CI)
 
Notes:
abnormal concretion or calcified deposit that forms around the teeth or dental prostheses. Obt. from sediment in wine manuf. Used in food processing as a nutrient, pH control agent and leavening agent Potassium bitartrate can be used with white vinegar to make a paste-like cleaning agent. It is a vital ingredient in Play-Doh and gingerbread house icing. This mixture is sometimes mistakenly made with vinegar and sodium bicarbonate (baking soda), which actually react to neutralise each other, creating carbon dioxide and a sodium acetate solution.; Potassium bitartrate, also known as potassium hydrogen tartrate, has formula KC4H5O6. It is a byproduct of winemaking. In cooking it is known as cream of tartar. It is the potassium acid salt of tartaric acid, a carboxylic acid.
