description Product Description
Aluminum ammonium sulfate is widely used in water treatment processes as a coagulant to remove impurities and suspended particles, ensuring cleaner and safer water. It is also employed in the paper industry to improve the strength and quality of paper products. In the textile industry, it serves as a mordant, helping dyes adhere to fabrics more effectively. Additionally, it finds application in fire extinguishers as a flame retardant and in baking powder as a leavening agent. Its astringent properties make it useful in certain medical and cosmetic formulations for skin care.
