What is Sodium Metasilicate CAS 6834-92-0 used for?

It is an alkaline inorganic builder used in powdered detergents, industrial cleaners, metal cleaning, water treatment, and silicate-based process formulations. It provides alkalinity, soil dispersion, and corrosion inhibition in cleaning systems.

What does Sodium Metasilicate do in detergent formulations?

It acts as a builder by raising alkalinity, improving soil removal, dispersing deposits, and helping protect metal surfaces through corrosion inhibition. These properties make it useful in heavy-duty powder and industrial cleaning products.

Is CAS 6834-92-0 the anhydrous form of Sodium Metasilicate?

Yes. CAS 6834-92-0 identifies anhydrous Sodium Metasilicate, which has a higher active Na2O and SiO2 content by weight than the hydrated forms. The pentahydrate is a separate hydrated grade and is often listed under CAS 10213-79-3.

How does Sodium Metasilicate behave in water?

It dissolves readily in water to form a strongly alkaline solution. This alkaline solution is effective for degreasing, buffering, and dispersing soils in cleaning and industrial process applications.

How should Sodium Metasilicate be stored?

Keep it in tightly sealed, moisture-resistant containers in a cool, dry area. The anhydrous product is hygroscopic and can absorb moisture and carbon dioxide from air, which may cause caking or reduce performance.
