Powder Sodium Mono Fluoro Phosphate
Powder Sodium Mono Fluoro Phosphate , also known as monosodium phosphate (MSP), is a white crystalline powder widely used as a food additive, buffering agent, and cleaning agent. It is a water-soluble salt of phosphoric acid and sodium, providing acidity control and emulsification in various industrial, food, and pharmaceutical applications. Its chemical stability and buffering capacity make it valuable in pH regulation and as a sequestrant.
