Ammonium polyphosphate is not typically considered a medical substance. It is more commonly used in two other applications:

• Flame retardant: Ammonium polyphosphate (APP) is a non-halogen flame retardant that is used in a variety of materials, including plastics, textiles, and wood. It works by decomposing and forming a char layer that helps to insulate the material and prevent the spread of fire.
• Fertilizer: In a specific instance, there is a liquid fertilizer product called Ammonium polyphosphate NP 11:37, which is a unique liquid nitrogen-phosphorus fertilizer produced in Russia. It is said to have high phosphorous and nitrogen content, good thermal stability, and low toxicity.
