Disodium octaborate is a borate of sodium, a chemical compound of sodium, boron, and oxygen — a salt with elemental formula Na2B8O13 or (Na+)2[B8O13]2−, also written as Na2O·4B2O3. It is a colorless crystalline solid, soluble in water.

Disodium octaborate is traded either as a liquid concentrate, or as the tetrahydrate Na2B8O13·4H2O, a white odorless powder. It is used as an insecticide,[3][4] and as a fungicide and algicide, and as a fire retardant.,[5][6] and as a boron micronutrient additive in fertilizers.[1] Trade names include Bora-Care, Borathor, Termite Prufe, Board Defense, Polybor,[6] Tim-bor,[7] and Can-Bor.
