What is Aluminium Potassium Sulphate Used for
Water Treatment: Employed as a coagulant in water treatment, enhancing water quality by eliminating impurities, particles, and organics.
Antiperspirants: A vital component in natural or crystal antiperspirants, it temporarily obstructs sweat glands, diminishing sweat production.
Pickling and Preserving: Applied in pickling, it upholds fruit and vegetable quality by sustaining texture and preventing color alteration.
Tanning and Leather Treatment: Valued in tanning, it enhances hide and skin quality, durability, and aesthetics.
Fire Retardant: It doubles as a fire retardant, heightening materials’ fire resistance.
Medicinal Uses: Traditionally, it acts as an astringent, aiding minor injuries, burns, insect bites, and mouth sores.
FAQ of Aluminium Potassium Sulphate
Yes, it is generally recognized as safe when used appropriately. It has been used for centuries in water purification, food processing, and personal care products. However, it can cause skin irritation for some people, so test on a small area first.
When added to water, it dissolves and forms positively charged aluminum ions that neutralize negatively charged suspended particles. These particles then clump together (flocculate) and settle, making water clear.
Our product meets strict limits: chloride ≤0.0005%, arsenic ≤0.00005%, sodium ≤0.02%, and heavy metals ≤0.0005%. Certificate of Analysis confirms all specifications.
Yes, it is chemically stable when stored properly. However, it effloresces (loses water) in dry air and can absorb moisture in very humid conditions.

The solid should be stored in a cool, dry, and well-ventilated area, away from incompatible materials like steel, aluminum, and strong bases.
