Useful:

• Chemical Classes: Metals -> Metalloid Compounds (Boron)
• Canonical SMILES: B1(OB2OB(OB(O1)O2)[O-])[O-].[Na+].[Na+]
• Inhalation Risk: Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly , especially if powdered.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system and kidneys. This may result in impaired functions.
• Effects of Long Term Exposure: Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the upper respiratory tract and testes. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
• Uses: Refined borax (Na2B4O7) is an additive in laundry products such as soaps and water-softening compounds. Also used for cosmetics, body powders, and the manufacture of paper and leather. Borax is an environmentally safe natural herbicide and insecticide. Sodium Tetraborate, is an important boron compound, which has a wide variety of applications. It is a component of many detergents, cosmetics, and enamel glazes. It is also used to make buffer solutions in biochemistry, as a fire retardant, as an anti-fungal compound for fiberglass, as a flux in metallurgy, neutron-capture shields for radioactive sources, a texturing agent in cooking, and as a precursor for other boron compounds.
