Borax, also known as sodium borate or sodium tetraborate, is a naturally-occurring mineral that has been used for centuries as a cleaning agent, insecticide, and even a food preservative. It is mostly found in the evaporite deposits of dry lake beds in California, Tibet, and Turkey.
What Are The Ingredients Of Borax?
Borax is composed of boron, sodium, and oxygen- three elements that are essential for many biological and industrial processes. Its chemical formula is Na2B4O7•10H2O, which indicates that it contains ten molecules of water to each molecule of boron and sodium borate.
The ten molecules of water are called “water of crystallization” or “water of hydration,” and are an integral part of the chemical structure of borax. They give the mineral its crystalline form and also contribute to its unique properties, such as its solubility in water and ability to absorb moisture.
Boron is a chemical element with the symbol B and atomic number 5. It is a metalloid, which means it has some properties of both metals and nonmetals. Boron is commonly found in the earth’s crust, and is present in rocks, soils, water, and plants. It is also used in many industrial applications, such as the manufacture of glass, ceramics, and fertilizers.
In borax, boron is present in the form of borate ions, which are negatively charged molecules that consist of one boron atom and three oxygen atoms. Borate ions are essential for many biological functions, such as building strong bones and cell walls.
Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white metal that is highly reactive with water and air. Sodium is found in many minerals and is essential for life. It is involved in many processes in the body, such as regulating fluid balance, transmitting nerve impulses, and maintaining normal heart rhythm.
In borax, sodium is present in the form of sodium ions, which are positively charged molecules that consist of one sodium atom and one oxygen atom. Sodium ions are important for many industrial processes, such as soap making and metal refining.
Oxygen is a chemical element with the symbol O and atomic number 8. It is a colorless, odorless, and tasteless gas that is essential for life. Oxygen makes up about 21% of the earth’s atmosphere and is the third most abundant element in the universe, after hydrogen and helium.
In borax, oxygen is present in the form of water molecules and borate ions. Water is important for many biological and industrial processes, such as hydration, cleaning, and chemical reactions.
How Is Borax Made?
Borax is typically extracted from the mineral brine, which is a saltwater solution that contains high concentrations of boron. The brine is first pumped to the surface and then filtered to remove impurities. The boron is then extracted from the brine using ion exchange or solvent extraction methods.
The boron is then combined with sodium hydroxide to form sodium borate, which is the primary component of borax. The sodium borate solution is then evaporated to remove the excess water, which results in the formation of borax crystals.
Uses Of Borax
Borax has many practical applications, both in the home and in industry. Here are some of the most common uses of borax:
- Laundry Detergent: Borax can be used as a laundry booster to help whiten clothes and remove stains. It can also help to soften hard water and reduce odors.
- Cleaning Agent: Borax can be used as an all-purpose cleaner to clean and deodorize surfaces around the house. It can also be used to unclog drains and remove rust stains.
- Insecticide: Borax can be used as a natural insecticide to control pests such as ants, cockroaches, and termites.
- Pesticide: Borax can be used as a herbicide to kill unwanted weeds and plants in gardens and on lawns.
- Preservative: Borax can be used as a food preservative to help prevent spoilage and extend the shelf life of food products.
While borax is generally considered safe for use in household and commercial applications, there are some safety precautions that should be taken when handling or using it.
Borax can be irritating to the skin, eyes, and respiratory system. It should not be ingested or inhaled. Ingestion of large amounts of borax can cause gastrointestinal upset, while inhalation can cause respiratory irritation and coughing.
It is important to follow the manufacturer’s instructions when using borax, and to wear appropriate protective gear, such as gloves and eye protection. It is also important to keep borax out of reach of children and pets.

FAQs About Borax
- What is the difference between borax and baking soda? Borax and baking soda are both used as cleaning agents, but they have different properties and uses. Borax is a natural mineral that is also used as a laundry booster and insecticide. Baking soda, on the other hand, is a chemical compound that is primarily used as a leavening agent in baking, but can also be used as a cleaning agent and deodorizer.
- Can borax be used to kill bed bugs? Yes, borax can be used as a natural insecticide to control bed bugs. It should be sprinkled around bed frames, mattresses, and other areas where bed bugs are present.
- Is borax safe for pets? Borax can be toxic to pets if ingested or inhaled. It is important to keep borax out of reach of pets, and to seek veterinary attention if a pet ingests or inhales borax.
- Is borax safe for plants? Borax can be used as a natural herbicide to kill unwanted weeds and plants in gardens and on lawns. However, it should be used with caution and only in areas where it will not harm desirable plants.
- Can borax be used as a fire retardant? Borax can be used as a fire retardant in some applications, such as in building materials and textiles. It works by releasing water molecules when exposed to heat, which helps to slow down or prevent the spread of fire.
