Used in the pharmaceutical industry accounts for about 10%, mainly used as anticoagulant, antiacid, orthodontic, cosmetics and so on. Used in chemical industry accounting for about 15%, used as buffer, complexing agent, metal cleaning agent, mordant, gelling agent, toner, etc.
In the electronic, textile, petroleum, leather, construction, photography, plastics, casting and ceramics and other industrial fields are very broad.
Citric acid is mainly used as sour agent, solvent enhancer, buffer, antioxidant, deodorant, flavor enhancer, gelling agent, toner and so on. In addition, citric acid also inhibits bacteria, protects color, improves flavor, promotes sucrose transformation and so on.
