Potassium Alum, FCC


Potassium Alum (KAl(SO₄)₂·12H₂O), also known as Potash Alum or Potassium Aluminum Sulfate, is a versatile compound with a wide range of applications. This FCC-grade compound is essential in water purification, leather tanning, dyeing, and fireproofing textiles. It is also used as a key ingredient in baking powder. In cosmetics, Potassium Alum serves as a natural deodorant, an aftershave treatment, and a styptic to stop minor bleeding from shaving. Potassium Alum crystallizes in regular octahedral shapes with flattened corners, making it a popular choice for crystal growth experiments. Its reliability, versatility, and unique properties make it a vital material for industrial, scientific, and cosmetic uses.
