Potassium Bitartrate

Potassium bitartrate is the monopotassium (acid) salt of tartaric acid (CAS 868-14-4; C4H5KO6, MW 188.18), the material traditionally known as cream of tartar and recovered from the potassium tartrate that deposits during winemaking. It delivers about 21% elemental potassium, among the lower-load potassium forms alongside the orotate and aspartate and above the gluconate, reflecting the large tartrate anion. Only sparingly soluble in cold water, it is a white crystalline powder also used as food additive E336. We manufacture it in powders, tablets and capsules.
