Anhydrous citric acid is a natural component and an intermediate product of physiological metabolism in animals and plants, and is also one of the most widely used organic acids in food, medicine, chemical industry and other fields. It is colorless transparent or chemicalbook translucent crystals, or granular, microgranular powder, odorless, although strongly sour, but pleasant, slightly astringent. It gradually weathers in warm air and slightly deliquescence in humid air.

Anhydrous citric acid is known as the first edible acidulant, and China's GB2760-1996 is stipulated as a permitted food acidity regulator. In the food industry, it is widely used as acidulant, solubilizer, buffer, antioxidant, deodorant, chelating agent, etc., and its specific uses are numerous.
Citric acid-based metal purification formulation, can effectively remove ferrous metal and non-ferrous metal surface oxide formation, as a weak organic acid, it can cause slight damage to the metal surface layer, but as a metal ion Chemicalbook chelating agent to accelerate the migration of metal oxides, in many steel impregnating systems, in order to eliminate metal oxide stress cracks and minimize the erosion and brittleness of high-strength steel, citric acid rust removal is used to replace inorganic strong acids.
