Frequently Asked Questions

AI
No. You must specifically look for 'food grade' labels if you intend to use alum for pickling or baking. Cosmetic-grade alum may contain additives or lack the purity standards required for consumption.
Potassium alum is generally preferred for skincare and food applications due to its natural properties, while ammonium alum is more common in industrial settings or specific textile processes.
