Overview
Sodium aluminosilicate ( CAS 1344-00-9 ), also known by its food additive designation E554 , is a synthetic inorganic salt derived from alumina and silica sources. It functions primarily as an anticaking agent in food and industrial applications.
This chemical prevents powder clumping and maintains free-flow characteristics in bulk materials. In food manufacturing, it is used in powdered products such as table salt, dried milk, and spice blends to maintain flowability through processing lines.
Water treatment operations use this compound as a coagulant and flocculant to remove suspended solids and improve clarification efficiency. In pulp and paper production, it contributes to retention and drainage control during sheet formation.
Textile and leather processing operations incorporate it as a stabilizer in dyeing and finishing baths. This helps to manage rheology and prevent precipitation during complex industrial manufacturing cycles.
The material is supplied as a fine white powder, with particle size specifications varying by application. Food-grade material is available to meet purity requirements under EU food additive regulations and international safety protocols.
Technical grades are also available for industrial uses in water treatment and paper manufacturing. These grades ensure consistent performance in heavy-duty applications where high-volume processing is required for operational success.
