The Ammonium Alum used in ManSpray is a mineral salt that is food grade and kosher. Ammonium Alum is often confused with Aluminum Chloride, Aluminum Chlorohydrate, Aluminum Zirconium or Potassium Alum all which are considered controversial.We, at ManSpray, carefully chose the variety that is a naturally occurring mineral salt, that is food grade, and has gone through the kosher certification. It is a completely different chemical structure than the minerals that are causing health concerns.That being said, please do not drink your ManSpray.
