Sodium Metasilicate Pentahydrate is an important inorganic alkaline compound widely used in industrial cleaning, detergents, water treatment, metal cleaning, construction, textile processing, and various chemical formulations. Known for its strong cleaning, alkalinity, buffering, and builder properties, it is an effective ingredient for applications where grease, oil, dirt, and mineral deposits need to be removed efficiently.
Sodium Metasilicate Pentahydrate is the hydrated form of sodium metasilicate, generally represented by the chemical formula Na₂SiO₃·5H₂O. It is typically supplied as white crystals, granules, or powder and dissolves readily in water to produce an alkaline solution.
Because of its combination of alkalinity and silicate properties, Sodium Metasilicate Pentahydrate is frequently used as a detergent builder, industrial cleaner, corrosion inhibitor, dispersing agent, and pH regulator.
Sodium Metasilicate Pentahydrate is widely used in heavy-duty industrial cleaners. Its alkaline nature helps remove grease, oil, carbonaceous deposits, and general industrial soils from equipment and surfaces.
It can be used in cleaning formulations for machinery, workshops, industrial floors, processing equipment, and other hard surfaces.
It acts as an effective builder in detergent formulations. Sodium Metasilicate Pentahydrate can improve cleaning efficiency by helping control water hardness and supporting the removal of oily and particulate soils.
It is commonly incorporated into powder detergents, industrial cleaning powders, and specialized cleaning formulations.
Sodium Metasilicate Pentahydrate is used in alkaline metal-cleaning formulations for removing oils, grease, and contaminants from metal components before further processing, coating, or painting.
Its silicate component can also contribute to surface protection in appropriately formulated cleaning systems.
In marine maintenance, alkaline silicate-based formulations can be used for cleaning machinery, decks, workshops, engine-room surfaces, and equipment contaminated with oil and grease.
For marine applications, the formulation should be selected according to the metal type, coating, contamination level, and cleaning method.
Sodium metasilicate compounds can be used in selected water-treatment and industrial water-conditioning applications because of their alkalinity, buffering properties, and ability to interact with certain dissolved or suspended contaminants.
The exact dosage depends on water chemistry and the intended treatment process.
Sodium Metasilicate Pentahydrate can be used in textile processing and cleaning formulations where alkaline conditions are required. It can assist in removing oils, dirt, and processing residues from textile materials.
Silicate compounds have applications in construction-related chemical formulations, including selected cement and concrete additives. Their chemical properties can be useful in formulations requiring silicate functionality and alkaline conditions.
Sodium metasilicate may be incorporated into certain pulp and paper processing chemicals, particularly where alkaline cleaning, stabilization, or processing conditions are required.

Both products are sodium metasilicate, but their hydration state differs.
Sodium Metasilicate Pentahydrate contains five molecules of water of crystallization and is represented as Na₂SiO₃·5H₂O.
Anhydrous Sodium Metasilicate does not contain this crystallization water and therefore has a different molecular weight and active-content calculation.
For industrial formulations, the appropriate grade should be selected based on concentration requirements, handling characteristics, solubility, and formulation specifications.
Sodium Metasilicate Pentahydrate should be stored in a cool, dry, and well-ventilated area in tightly closed packaging. Because it is alkaline, appropriate protective equipment should be used during handling.
Avoid unnecessary contact with skin and eyes, and always consult the product's Safety Data Sheet (SDS) for detailed handling, storage, transportation, and first-aid requirements.
When sourcing Sodium Metasilicate Pentahydrate for industrial use, buyers should consider:
Product purity and grade
Consistent quality between batches
Packaging options
Technical specifications
Availability and supply capacity
Material Safety Data Sheet (SDS)
Certificate of Analysis (COA)
Application-specific technical support
Reliable logistics and delivery
A dependable supplier can help select the appropriate grade and packaging according to the customer's application and required quantity.
Sodium Metasilicate Pentahydrate is a versatile alkaline silicate widely used in industrial cleaning, detergent manufacturing, metal cleaning, marine maintenance, textile processing, water treatment, and other chemical applications. Its strong alkalinity, detergent-building capability, dispersing properties, and cleaning performance make it an important raw material for numerous industrial formulations.
For manufacturers, distributors, and industrial users looking for Sodium Metasilicate Pentahydrate, selecting a consistent-quality product from a reliable chemical supplier is essential for achieving stable formulation performance.
