Aluminium Sulphate (Non Ferric) (Al₂(SO₄)₃)
Aluminium Sulphate (Non Ferric) Non-Ferric Alum is a high-purity, low-iron form of Aluminium Sulphate, typically appearing as a white or near-white crystalline solid. It is favored for applications where clarity, whiteness, or color precision is critical—such as drinking water purification, white paper production, cosmetics, and high-end textiles. Unlike Ferric Alum, it does not impart a yellow or brown tint, making it ideal for color-sensitive processes. Supplied in powder, granule, or slab form, it offers excellent solubility and fast reactivity.

Preferred for potable water due to its low iron content, which ensures color-free and clear treated water. Improves paper sizing and ink absorbency. Prevents pitch deposits and enhances filler retention. Used as a mordant to enhance dye bonding to natural fibers. Ideal where bright and pure dye shades are required without iron interference. Helps in deliming hides and softening leather during tanning without darkening the leather. Used in deodorants, aftershaves, and topical antiseptics. Also found in veterinary products and tablets as astringents and clarifiers. Applied in chemical analysis and sample preparation, especially where iron contamination must be avoided.
