Sodium selenate
Other names: Sodium selenate
Harm score: 2 (Derivatives of natural substances)
Sodium selenate, also known as Sodium selenate, is a chemical that is widely used in industry. It is a crystalline white substance that is highly soluble in water. Sodium selenate is non-flammable but can decompose into toxic selenite dioxide when exposed to temperatures above 650°C. It is stable under normal conditions but may react with reducing agents. It is important that it be stored in a dry environment because it is hygroscopic, meaning that it readily absorbs moisture from the air.
Although Sodium selenate is often considered toxic and dangerous if consumed in excess, it is found in very small concentrations in a number of food and cosmetic products, and is permitted in them by the European Union. For example, it is added to shampoos as an antifungal ingredient, or to animal feed to enhance their healthy nutrition. Sodium selenate is also used as an insecticide and fungicide in agriculture or as a solvent in some industrial processes. In addition, this substance can be used in some photographic and metallurgical processes. Nevertheless, it must be used with caution and all recommendations for its proper storage and use must be followed to avoid possible health problems.
