Product Overview

Tartaric acid is an organic acid that exists as a crystalline solid and usually comes in two forms: L-tartaric acid and D-tartaric acid. Tartaric acid usually appears as colorless or translucent crystals or crystalline powder. The density of tartaric acid is about 1.7-1.8 g/cm3. 0.1 M solution of tartaric acid ph around 2.2. It is easily soluble in water and alcohol solvents, and the solubility increases with the increase in temperature. Tartaric acid is widely used in the food industry, pharmaceutical manufacturing, cosmetics and dye industries.

Tartaric acid exists in various forms based on its optical properties, including anhydrous DL-tartaric acid, monohydrate DL-tartaric acid, l tartaric acid, and d tartaric acid.

DL-tartaric acid is the most common form of tartaric acid. It is primarily used in the food industry and can serve as an acidulant and antioxidant. L-tartaric acid is used as an acidulant in certain food processing applications, in the pharmaceutical industry, and as a catalyst or pH regulator in the resin finishing of polyester fabrics. D-tartaric acid is typically used in the pharmaceutical industry to prepare specific drug salts.

The main application of Tartaric Acid

Tartaric acid in baked goods reacts with baking soda to provide the gas power for fermentation and optimal leavening. It is a common source of acid in cake, bread, biscuits, and muffin recipes.
As an acidulant, tartaric acid imparts a clean, sour taste to beverages such as soft drinks, juices, and flavored waters.
Tartaric acid in dairy processing precipitates milk proteins, thereby separating whey and casein by coagulation.
Tartaric acid in skincare lowers and balances pH in beauty creams, serums, and cleansers, enhancing their effectiveness and skin compatibility.
Tartaric acid in pharmaceuticals is used as an excipient to adjust solubility and improve chemical stability. Extended-release tablets contain tartaric acid to control drug dissolution.
Tartaric acid is used in fabric and leather dyeing to fix color by forming metal complexes.
