Are all crystal deodorants alike?
No. There are two types of crystal deodorant stones available in the market, those made from potassium alum stone, like Verdan crystal deodorant products, and those made from chemically synthesized alum. Potassium Alum is a naturally occurring mineral found in isolated quarries throughout the world. Synthetic alum is chemically manufactured in a factory using Aluminium hydroxide (ATH).
