Disodium octaborate tetrahydrate
Disodium octaborate tetrahydrate, an alkaline salt, is produced in two forms. One is a clear, liquid concentrate, which can be mistaken for corn syrup if repackaged and not properly labeled or it is packaged as a white, odorless, powdered chemical substance that is not flammable, combustible, or explosive and has low acute oral and dermal toxicity. This salt, which is commonly confused with boric acid, is used as an insecticide and is commonly sold in liquid or powder form. It is also effective against fungi and algae. It has an infinite shelf life and is not affected by temperature. "Bora-Care" is the liquid form suitable for use in a sprayer. The powdered brands are "Tim-Bor," "Borathor," "Termite Prufe" or "Board Defense" as sold in the United States. This chemical is also a flame-retardant. In the liquid form, it is commonly diluted and sprayed on wood surfaces to kill termites, powder post beetles, carpenter ants, fungi and algae. It is also available as pellets for embedding in structural wood. This alkaline salt is not to be confused with boric acid (an acidic chemical) or the laundry detergent additive used for stains.
