Potassium aluminum sulfate (𝐾𝐴𝑙(𝑆𝑂4)2⋅12𝐻2𝑂), commonly known as potash alum or fitkari, is a versatile white crystalline compound used primarily as a water coagulant, astringent/antiseptic in personal care (deodorants, aftershaves), leather tanning, and mordant in textiles. It works by shrinking tissues and inhibiting bacteria. Wikipedia +4Uses and Applications

• Personal Care: Used as a natural deodorant/antiperspirant to block odor-causing bacteria and as a styptic pencil to stop bleeding from small cuts.
• Water Treatment: Acts as a coagulant to remove impurities and suspended particles from water.
• Industrial/Commercial: Used in leather tanning, textile dyeing as a mordant, and historically in baking powder.
• Medical/Dentistry: Employed as an astringent to shrink tissues or reduce bleeding.
