Chemical Description


  • Boric Acid, also known as hydrogen borate, is a weak, monobasic Lewis acid of boron. It is often used in the form of white granules that dissolve in water. This compound is known for its antiseptic, insecticidal, and flame retardant properties.
  • In industrial applications, Boric Acid is used as a flame retardant, where it reduces the flammability of materials by inhibiting the release of combustible gases. It's also employed in the manufacture of glass and fiberglass, enhancing the strength and chemical resistance of the final products.
  • Pharmaceutically, Boric Acid serves as an antiseptic agent. It's used in various products, such as eye wash solutions, antiseptic creams, and powders, to prevent the growth of bacteria and fungi.
  • In agriculture, Boric Acid is utilized as a nutrient in plant growth, particularly for crops requiring boron. It's also a component in pesticides, helping to control insects, fungi, and weeds.
  • For pest control, Boric Acid is a popular ingredient in baits for cockroaches, termites, and other pests. Its effectiveness lies in its toxicity to insects while being relatively safe for humans and pets when used appropriately.
  • In the food industry, Boric Acid can act as a preservative, though its use is restricted in many countries due to safety concerns. It helps to inhibit the growth of bacteria and fungi, extending the shelf life of certain foods.
  • Boric Acid finds its use in the production of ceramics and enamels, where it improves the texture, glaze, and durability of the final products.
  • Due to its properties, Boric Acid is also valuable in nuclear power plants as a neutron poison, controlling the rate of fission in nuclear reactors.
  • Despite its wide range of applications, it's important to handle Boric Acid with care, as excessive exposure can lead to health issues. Its low toxicity to humans makes it a preferred choice in various applications, balancing efficacy with safety.
