M.W.: 202.14 (Average value)
CAS No.: 1344-00-9
Packaging: 1kg/bag/carton; 5kg/bag/carton; 20kg/bag/drum
Appearance:
White or almost white, fine, light, amorphous powder.
Quality Standard: EP11.0
Features:
Aluminium Sodium Silicate is a complex aluminosilicate with a framework structure composed of interconnected Si-O and Al-O tetrahedrons. The structure is similar to that of amorphous SiO₂, with sodium ions and water molecules often present within the pores of the aluminosilicate network. This framework is characterized by its ability to form stable networks with varying degrees of polymerization.
Applications:
Dosage Form | Application | Usage Amount |
Tablets, Capsules | Anti-caking agent, filler | 0-2% |
Granules | Carrier, controlled-release material | 0-2% |
Suspensions, Emulsions | Stabilizer, emulsifier | 0.5-2% |
Advantages:
■ Low Toxicity and Safety.
Aluminium Sodium Silicate is widely recognized as safe for pharmaceutical use, with low aluminum content and minimal absorption in the human body.
Approved for use in both food and pharmaceuticals as an anti-caking agent or carrier.
■ Versatility
Functions as an anti-caking agent, adsorbent, emulsifier, and stabilizer, meeting diverse formulation needs.
■Chemical Stability.
Exhibits good chemical stability in acidic, neutral, and weakly alkaline environments.
Incompatibilities
■ Reaction with Acids: Aluminium Sodium Silicate may gelatinize and release a small amount of heat when in contact with acids.
■ Incompatible Materials: Avoid contact with strong acidic substances.
Storage
In an airtight container.
