What Are The Regulations Governing The Use Of Sodium Tungstate In Industry?
Sodium tungstate is regulated by various government agencies in different countries depending on its intended use. In the United States, for example, sodium tungstate is regulated by the Environmental Protection Agency (EPA) under the Toxic Substances Control Act (TSCA). The TSCA requires manufacturers and importers to submit pre-manufacture notifications to the EPA before producing or importing sodium tungstate, unless it is already listed on the TSCA Chemical Substance Inventory.
In Europe, sodium tungstate is regulated by the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation, which requires companies to register substances with the European Chemicals Agency (ECHA) before they can be marketed or used in the European Union. Sodium tungstate is also subject to various national regulations, such as the German Chemicals Act and the French Order of 19 May 2004.
The use of sodium tungstate is typically restricted to certain industrial applications, such as in the production of tungsten metal, ceramics, and catalysts. It may also be used as a mordant in the textile industry and as a corrosion inhibitor in some industrial processes. The specific regulations governing its use will depend on the intended application and the jurisdiction in which it is being used.
