TANNIC ACID Chemical compatibility with O-rings, rubbers, & plastics

Tannic acid is a yellow to light brown amorphous powder with the chemical formula C76H52O46, derived from plant sources such as oak bark and gallnuts. It is used in various industrial, pharmaceutical, and food applications, primarily as a tanning agent, clarifying agent, and antioxidant. In the leather industry, tannic acid is employed to convert animal hides into leather, providing durability and resistance to decay. In the food and beverage industry, it is used to clarify wine and beer, remove proteins and other impurities, and act as a flavoring agent. Tannic acid is also used in the pharmaceutical industry for its astringent and anti-inflammatory properties, making it a valuable ingredient in certain medications and topical treatments. Proper handling and storage of tannic acid are essential to maintain its quality and prevent moisture absorption. Safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are crucial to prevent skin and eye irritation and other health hazards.
