Sodium Metasilicate Pentahydrate: A Versatile Solution for Detergent and Industrial Applications

Sodium Metasilicate Pentahydrate (Na2SiO3 · 5H2O) is one of the most widely used forms of sodium metasilicate. It appears as white crystalline granules and dissolves easily in water to form an alkaline solution.

Key Advantages

Property Benefit
Oil Emulsification & CleaningExcellent grease and oil removal performance
Water SofteningEffective calcium and magnesium ion binding
pH BufferingStrong buffering for stable alkaline conditions
Corrosion ProtectionProtection for aluminum, zinc, and non-ferrous metals
Dispersion & SuspensionImproved dispersion of solid particles

Main Applications

Detergent Industry

Widely used in phosphate-free detergent formulations as an environmentally friendly builder. Applied in laundry powder, liquid detergents, industrial cleaning formulations, and heavy-duty cleaners.

Metal Surface Treatment

Disperses solid contaminants and emulsifies oily residues while providing buffering and corrosion inhibition. Suitable for metal cleaners, degreasing agents, and surface preparation chemicals.

Ceramic & Construction

Acts as grinding aid, water reducer, and slurry dispersing agent. Also used in papermaking de-inking, acid-resistant construction materials, and drilling mud conditioning.

Anhydrous Sodium Metasilicate: High-Performance Solution for Concentrated Formulations

Anhydrous Sodium Metasilicate, also known as zero-water sodium metasilicate, is an advanced form developed for high-performance industrial applications. Unlike hydrated grades, it contains no crystal water.

Advantages

Advantage Description
Higher Active ContentSignificantly higher solid content enabling compact formulations and reduced transport cost per active ingredient
Bleaching CompatibilityExcellent stability with organic chlorine compounds, peroxide-based bleaching agents, and bleach activators
Strong DegreasingOil absorption up to ~70%, excellent for ultra-concentrated detergents, industrial degreasers, and metal treatment
