? Did You Know?

Sodium Aluminium Silicate occurs naturally in Zeolite minerals and Albite and other feldspars. Many people consume it daily without realizing it's also a listed food additive.

Beyond food, Sodium Aluminium Silicate is also used in cosmetics, medicine, industrial applications, household products. Its versatility makes it one of the most multi-purpose chemical compounds in everyday life.

In the EU, Sodium Aluminium Silicate has a "quantum satis" authorization — Latin for "as much as needed." This means there's no specific maximum limit; manufacturers use only what's technologically necessary.

Natural Occurrence

While sodium aluminium silicate occurs in nature as zeolites and feldspars, food-grade material is synthetically produced for purity and consistent properties.

Zeolite mineralsAlbite and other feldspars

Manufacturing

Method: chemical synthesis

Produced by reacting sodium silicate with aluminum sulfate or aluminum hydroxide, followed by washing, drying, and milling. The synthetic process controls particle size and purity.

Applications Beyond Food

Cosmetics

Absorbent, bulking agent, opacifier.

Medical

Rare use as excipient.

Industrial

Zeolite catalysts, water softening, detergents, molecular sieves.

Household

Water softening, some cleaning products.
