Sodium aluminosilicate

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.

Where is Sodium aluminosilicate used?

• Food: anticaking agent in table salt, dried milk and spice blends to maintain flowability through processing lines
• Water treatment: coagulant and flocculant that removes suspended solids and improves clarification efficiency
• Pulp and paper: retention and drainage control during sheet formation
• Textile and leather: stabilizer in dyeing and finishing baths
• It prevents powder clumping and maintains free-flow characteristics in bulk materials.

Commercial specifications

• Particle size specifications vary by application
• Food-grade material meets purity requirements under EU food additive regulations and international safety protocols
