Citric acid is an important organic acid, also known as citric acid, colorless crystals, often containing a molecule of crystal water, odorless, with a strong sour taste, easily soluble in water. Its calcium salt is more soluble in cold water than in hot water, and this property is often used to identify and separate citric acid. Anhydrous citric acid can be obtained by controlling the appropriate temperature during crystallization. It has many uses in industry, food industry, cosmetic industry, etc.
Used in chemical industry and textile industry Citric acid can be used as chemical analysis reagent in chemical technology, used as experimental reagent, chromatographic analysis reagent and biochemical reagent; used as complexing agent, masking agent; used to prepare buffer solution. Using citric acid or citrate as a builder can improve the performance of washing products, can quickly precipitate metal ions, prevent pollutants from re-attaching to the fabric, maintain the necessary alkalinity for washing; disperse and suspend dirt and ash; It is an excellent chelating agent to improve the performance of surfactants; it can be used as a reagent for testing the acid resistance of architectural ceramic tiles.
For environmental protection Citric acid-sodium citrate buffer is used for flue gas desulfurization. China is rich in coal resources, which constitute the main part of energy. However, there has been a lack of effective flue gas desulfurization technology, resulting in serious atmospheric SO2 pollution. Research on effective desulfurization process is a top priority. Citric acid-sodium citrate buffer solution is a desulfurization absorbent with great development value due to its low vapor pressure, non-toxicity, stable chemical properties, and high absorption rate of SO2.

Used in cosmetics Citric acid is a kind of fruit acid. Its main function is to speed up keratin renewal. It is often used in lotions, creams, shampoos, whitening products, anti-aging products, and acne products. The renewal of keratin is helpful for the exfoliation of melanin in the skin, the reduction of pores, and the dissolution of blackheads.
