Citric acid can be used as a chemical analysis reagent in chemical technology, as an experimental reagent, a chromatographic analysis reagent and a biochemical reagent; as a complexing agent, masking agent; used to prepare buffer solutions. 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.
Formaldehyde pollution of clothing is a very sensitive problem. Citric acid and modified citric acid can be made into a formaldehyde-free anti-wrinkle finishing agent for the anti-wrinkle finishing of pure cotton fabrics. Not only the anti-wrinkle effect is good, but also the cost is low.
