Trisodium Citrate Dihydrate (CAS 6132-04-3) is the tribasic sodium salt of citric acid, supplied as a white crystalline powder that buffers acidity and sequesters calcium ions in food, pharmaceutical, and personal care applications. Our Food Grade crystalline powder offers high solubility and a pleasant, slightly salty taste for flavor enhancement.
In the medical field, it is a critical anticoagulant used in blood collection tubes and hemodialysis processes. Its ability to chelate calcium ions makes it an effective stabilizer in pharmaceutical formulations and personal care products.
As a highly biodegradable and eco-friendly chemical, it serves as an alternative to phosphates in detergent applications. It provides excellent thermal stability and remains free-flowing under proper storage conditions.
