Description
Natural tartaric acid is an organic acid that occurs naturally in grapes and other fruits. It is extracted from the sediments that form during the wine fermentation process, which is why it is also known as tartaric acid. It is a white, crystalline substance with an acidic taste and is used in the chemical industry.

Applications
Natural tartaric acid is applied in various ways, for instance:
1. Cosmetics
Tartaric acid is sometimes used in skin care products because of its exfoliating properties that it helps remove dead skin cells.
2. Chemical Industry
Tartaric acid is used as a starting material for the production of other chemicals, such as potassium tartrate and potassium bitartrate, which in turn are important in Agriculture and Industrial Applications.
