Physical properties
Boric acid exists in the form of colorless crystals or as a white powder and is soluble in water. It occurs naturally in the condensate from volcanic steam vents (suffioni). Commercially, it is made by treating borate minerals (e.g. kernite, Na2B4O7.4H2O) with sulphuric acid followed by recrystallization.

Uses
Boric acid is used in the manufacture of glass (borosilicate glass), glazes and enamels, leather, paper, adhesives, and explosives. It is widely used (particularly in the USA) in detergents, and because of the ability of fused boric acid to dissolve other metal oxides it is used as a flux in brazing and welding. Because of its mild antiseptic properties it is used in the pharmaceutical industry and as a food preservative.boric acid is an effective preservative against yeast. It is used in concentrations of 0.01 to 1.0 percent and has fair to good antiseptic properties. It may also be used as a buffer and denaturant. Boric acid is prepared from sulfuric acid and natural borax. It can cause skin rashes and irritation if used in high concentrations. The use of boric acid in cosmetic preparations is no longer very popular.

Indications
Boric Acid is a weakly acidic hydrate of boric oxide with mild antiseptic, antifungal, and antiviral properties. The exact mechanism of action of boric acid is unknown; generally cytotoxic to all cells. It is used in the treatment of yeast infections and cold sores.Boric acid, 600 mg in a gelatin capsule, used intravaginally daily for 14 days, has been reported effective even in resistant Candida infections.
