Cream of Tartar, also known as potassium bitartrate, is a white powdery substance that is a byproduct of winemaking. It is processed from the potassium acid salt of tartaric acid. Cream of Tartar can be used in baking or as a cleaning agent when mixed with an acidic substance, such as lemon juice or white vinegar. The Cream of Tartar USP/NF/FCC/Food Grade available at Lab Alley is appropriate for food, personal care, household, and chemistry uses due to its purity level and certification from the United States Pharmacopeia (USP).
