Boric acid, also known as boracic acid or orthoboric acid, is a naturally occurring compound containing the elements boron, oxygen, and hydrogen. Boric acid crystals are white, odorless, and nearly tasteless. It looks like fine table salt in the granular form or like baby powder in the powdered form.

Boric acid is one of the most commonly produced borates and is widely used throughout the world in the pharmaceutical and cosmetic industries, as a nutritional supplement, flame retardant, in the manufacture of glass and fiberglass, and in the production of wood preservatives to control pests and fungus
