Aluminum calcium silicate

Aluminum calcium silicate (CAS 1327-39-5), also designated E556 in food regulation, is a synthetic aluminosilicate mineral used commercially as an anticaking agent and flow conditioner.

It prevents clumping and moisture absorption in powdered materials across food, pharmaceutical, and industrial applications. In food manufacturing, E556 is incorporated into table salt and seasonings.

These dry mixes maintain free-flowing characteristics through processing and shelf life. Pharmaceutical formulators use it as an excipient in tablet and powder blends where consistent flowability is required.

It is also utilized where compressibility is necessary for manufacturing. In oil and gas operations, it functions as a component in drilling fluid formulations and cement slurries for wellbore applications.

The material contributes to fluid loss control and structural integrity. Water treatment and mining operations employ it for coagulation and flocculation support, aiding in the removal of suspended solids.

Aluminum calcium silicate is supplied as a fine white powder in both food-grade and technical-grade specifications. Food and pharmaceutical supply conforms to relevant compendial requirements.

These standards include FCC and Ph. Eur. monographs where applicable. Technical-grade material is available for industrial use in bulk quantities suited to drilling and water treatment.

The product is also ideal for mineral processing operations. This versatile mineral ensures efficiency and quality across a wide range of global manufacturing and processing sectors.
