SODIUM CITRATE Chemical compatibility with O-rings, rubbers, & plastics

Sodium Citrate is a white, crystalline organic compound with the chemical formula C6H5Na3O7. It is widely used in various industrial, chemical, and food applications. In the food industry, Sodium Citrate is used as a preservative, flavoring agent, and emulsifier, providing a mild, tart taste and enhancing the stability of food products. It is also employed in the production of certain pharmaceuticals and cosmetics, where it acts as a buffering agent and stabilizer. In the chemical industry, Sodium Citrate is used as a reagent in the synthesis of various organic compounds and as a chelating agent in water treatment. Proper handling and storage of Sodium Citrate are essential to maintain its quality and prevent moisture absorption. It is generally considered safe for consumption and use, although proper safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are essential to prevent irritation and other health hazards.
