How Is Boric Acid Made?

History

Borates (boron-containing minerals such as borax and boric acid) most commonly originate in dried salt lake beds of desert or dry regions. Boric acid has been used since ancient times to fireproof clothing. A century ago it was used as a food preservative until that application was outlawed. Depending on its form, boric acid can resemble table salt or baby powder.

Components

Boric acid, (also referred to boracic acid ororthoboric acid) is a natural substance (often present in soil and water) composed of oxygen, hydrogen and boron. It is produced from the combined response of borate minerals with sulfuric acid (highly corrosive acid made from sulfur dioxide that's commonly used in the chemical industry).

Boron

Boric acid and its chemical associations are pesticides that originate from the element boron. Boron is an essential nutrient for fish. If the boron concentration in water is inadequate, fish will fail to flourish. At the same time, high levels of boron are poisonous to fish. Boron is typically found in combination with boric acid or borates.
Boron is a non-metallic element that emerges both in a hard black crystal and in the form of a yellow or brown powder. Foods including grains, nuts, fruits and vegetables are rich in boron. Boron is frequently mixed with other similar components such as sodium to make salts and with oxygen to make boric acid.

Uses

Boric acid is made to be used in wide array of products including antiseptics, paints, pest control, medicated powder, lotions, eye washes, laundry additives, anti-aging products, enamels and flame retardant. Boric acid and borates stand apart from most pesticides because of their naturally occurring compounds.
