Soluble in water,alcohol. glycerin, others and esscntial oils, odorless,slightly sour and bitter after taste. Exposure does not change in the air, and can volatilize with water vapor.When heated to 101-105 °C, a molecule of water is lost then form metaboric acid; when heated for a long time at 104-160°C, it is converted into pyroboric acid,and anhydrous is formed at higher temperaturc.
