DescriptionECHEMI Editorial ReferenceSodium metasilicate is a type of silicic acid salt and is classified as an inorganic salt products, and its molecular formula is Na2SiO3•nH2O. It is a non-toxic, odorless and harmless white powder or crystalline particle. It is soluble in water, but not in alcohols or acids. Its aqueous solution is alkaline and is capable of hygroscopy and deliquescence when in contact with air. It has purifying, emulsifying, dispersing, moistening, permeating and PH buffering abilities. Sodium metasilicate is

Sodium silicate appears as a powdered or flaked solid substance. Strong irritant to skin, eyes, and mucous membranes. May be toxic by ingestion. Concentrated aqueous solutions used as a glue.|Sodium silicate is an inorganic sodium salt having silicate as the counterion. It contains a silicate ion.
White, granular powder. Soluble in water; p H of 1% solution 12.7. Noncombustible.
The metasilicates are highly water soluble, but insoluble in alcohol, acid, and salt solutions. Solutions of sodium metasilicate, when heated or acidified, are hydrolyzed to free sodium ions and silicic acid. In moist air, they are corrosive to metals, including zinc, aluminum, tin, and lead, forming hydrogen gas. They are all strong bases reacting violently with acid.CertificatesBasic Info-

Air and Water Reactions:Deliquescent. Water soluble [Handbook of Chemistry and Physics].
Reactive Group:Salts, Basic
Reactivity Profile:SODIUM SILICATE contains a variable amount of water of hydration. Rate of dissolution depends on the degree of hydration, the amount of water that is used as solvent (less soluble in large amounts of water) and the temperature (higher temperature means quicker solution). Aqueous solutions react as bases. Reacts violently with fluorine [Lewis.]
Autoignition Temperature:Not flammable (USCG, 1999)
Corrosivity:Sodium metasilicate is considered to be too corrosive to be widely used in consumer product laundering formulations.
