Description
A white crystalline powder that occurs in nature as the mineral sassolite. Commercially, boric acid is primarily synthesized from Borax. It is used to weatherproof wood and fireproof fabrics. It is also used to produce glass, enamels, and porcelain. Boric acid is used as an Insecticide for cockroaches, Silverfish, and black carpet beetles usually in a mixture with silica dust called B + S. It has been used as an antibacterial eyewash, a buffer in photo processing solutions, and a mordant for printing and dyeing.
