What Is Calcium Silicate?
Calcium silicate is a white flowing powder used as an anti-caking agent in baking powder, table salt, and spice blends. It has extremely high oil and water absorption capacity, maintaining free-flowing properties even under high humidity. JECFA considers it acceptable with no ADI specified. EFSA confirmed safety in 2018. It is also used in building materials (cement, insulation) at industrial grade, but food-grade calcium silicate is produced to specific purity standards. Approved in EU, USA, Japan, Canada, and Australia for anti-caking applications.
? Did You Know?
Calcium Silicate occurs naturally in Wollastonite mineral and Various calcium silicate minerals. Many people consume it daily without realizing it's also a listed food additive.
Beyond food, Calcium 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, Calcium 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
Calcium silicate occurs naturally as wollastonite and related minerals. Food-grade calcium silicate is typically synthetically produced for purity and consistency.
Manufacturing
Produced by reacting calcium oxide or calcium hydroxide with silicon dioxide (silica) at high temperatures, or by precipitation from solutions of calcium and silicate salts. Food-grade material is purified and milled to fine powder.
Applications Beyond Food
Absorbent, bulking agent in powders.
Tablet and capsule diluent, glidant.
Insulation, ceramics, cement, fireproofing materials.
Not typically used in household products.
