  Uses	Citric acid is a relatively strong acidic organic acid. It is the largest organic acid produced by biochemical methods in the world. Citric acid and salts are one of the pillar products of the fermentation industry. They are mainly used in the food industry, such as sour agents and solubilizers. , Buffers, antioxidants, deodorants, flavor enhancers, gelling agents, toners, etc. are used as experimental reagents, chromatographic analysis reagents and biochemical reagents, and also used in the preparation of buffers. In the detergent industry, it It is an ideal substitute for phosphate. Boiler chemical cleaning pickling agent, boiler chemical cleaning rinsing agent, also used to prepare medicine cooling agent, detergent, etc.
  Hazard category	General chemicals
  Fire-fighting measures	This thing is not combust
  Emergency treatment	This substance is non-toxic
  Packaging, storage, transportation	Packed in a lined woven bag or kraft paper bag 25 kg/bag. The citric acid monohydrate loses crystal water in dry air or when heated to about 40 degrees. It is slightly deliquescence in humid air. Dilute citric acid aqueous solution can Ferment when standing. Therefore, the solid monohydrate or anhydrous should be stored in an airtight container in a cool and dry place.
