Sodium phosphate is a colorless to white crystalline powder that is commonly used as a food additive and in the production of detergents and fertilizers. It is a source of phosphorus and sodium ions and is often used in processed foods to improve texture and flavor, as well as to act as a preservative. It is also used in medical settings to help regulate electrolyte levels in the body and as a laxative. Sodium phosphate can have potential negative health effects when consumed in large amounts, so it is important to use it in moderation and according to recommended guidelines.
