Product Applications
Citric Acid Monohydrate is a naturally occurring tricarboxylic acid commonly found in citrus fruits. It is widely utilized as a pharmaceutical excipient because of its antioxidant properties, helping preserve the stability of active ingredients and extend product shelf life. It also functions as a preservative and acidulant for pH regulation. In addition, citric acid acts as an anticoagulant by binding calcium ions in the blood. It is further used as an acidifying agent, food additive, and synergist to enhance the effectiveness of antioxidant formulations.
