The product is colorless translucent crystals or white particles, or white crystalline powder, usually containing a molecular crystal water, odorless, taste very acid, soluble in water, alcohol and ether. Its calcium salt is more easily dissolved in cold water than hot water, which is often used to identify and isolate citric acid. Control the suitable temperature can be obtained with anhydrous citric acid when crystallization. The aqueous solution has acidity. Slightly to be weathered in dry air, deliquescence in moist air.  175℃ above the decomposition of it will release water and carbon dioxide.

AP­PLI­CA­TION


 

Food & Beverage Industry

 

Anhydrous citric acid is used in solid beverages. Salts of citric acid such as calcium citrate and ferric citrate, are fortifiers that need to add calcium ions and iron ions in some foods. Esters of citric acid such as triethyl citrate, can be used as nontoxic plasticizers to make plastic films for food packaging, and are sour agents and preservatives in beverage and food industries.

 

 

Chemical Industry

 

Citric acid can be used as reagent for chemical analysis, experimental reagent, chromatographic reagent and biochemical reagent in chemical technology; Used as complexing agent and masking agent; Used to prepare buffer solution. Using citric acid or citrate as builder can improve the performance of washing products, precipitate metal ions quickly, prevent pollutants from reattaching to fabrics, and maintain the necessary alkalinity for washing; Disperse and suspend dirt and ash; Improving the performance of surfactant is an excellent chelating agent; It can be used as a reagent for testing the acid resistance of building ceramic tiles.


 

 

Cosmetics

 

Citric acid is a kind of fruit acid, and its main function is to accelerate cutin renewal. It is often used in lotion, cream, shampoo, whitening products, anti-aging products, acne products, etc. The renewal of cutin contributes to the exfoliation of melanin in skin, the narrowing of pores and the dissolution of blackheads. For example, Biotherm Biosensitive Softening Foaming Cleansing Water makes the skin soft and comfortable, and the skin color is fresh and pure.
