Description and Uses
DL-Tartaric acid is used as a synergist for antioxidants, emulsifier, sequestrant and flavoring agent. It is also added with citric acid to prepare effervescent salts, thereby enhancing the taste of oral medications. It is also utilized in pigments, processing aids, ink, toner and colorant products. It acts as a chelating agent in metal and farming industries. Further, it is used as lubricant and grease. It is mixed with sodium bicarbonate and used as a leavening agent in food preparation. In the pharmaceutical industry, it is utilized in the preparation of tartar emetic, which is used in cough syrup as an expectorant.
