Regulatory Information
Silicic acid (H2SiO3), disodium salt, pentahydrate is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Silicic acid (H2SiO3), disodium salt, pentahydrate are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)
Sodium metasilicate, pentahydrate: Does not have an individual approval but may be used under an appropriate group standard
Hazards Summary
Corrosive to moistened rabbit skin; Sodium metasilicate was not sensitizing in a local lymph node assay study of mice; Similar uses and adverse effects are expected from the hydrous and anhydrous forms (Sodium metasilicate pentahydrate, Sodium metasilicate nonahydrate, Sodium metasilicate, Sodium silicate, and Potassium silicate). One case of occupational contact urticaria reported from sodium silicate; [OECD SIDS: Soluble Silicates - 2004] Causes burns; Inhalation may cause corrosive injuries to upper respiratory tract and lungs; Harmful by ingestion; [Sigma-Aldrich MSDS] See Sodium metasilicate.

Uses
Permitted for use as an inert ingredient in non-food pesticide products; [EPA] Alkali metal silicates are used as starting materials for products like silicas and zeolites, in detergents and cleaners, and pulp and paper production; Also used to a lesser extent in soil stabilization and sealing, adhesives and binders (construction materials, paperboard and cardboard, ceramic binders, refractories, welding rods, and foundry molds and cores), surface coatings (titanium dioxide production, paints for masonry and glass, and spray coatings for tunnel construction and mining), water/wastewater treatment, enhanced oil recovery, and textile processing (bleach and dye stabilizing); [OECD SIDS: Soluble Silicates - 2004] Generally regarded as safe (GRAS) by the FDA for use in fruit and vegetable washes, sanitizers for food-contact surfaces, and other indirect food contact uses; [NTP]
