Disodium octaborate is traded either as a liquid concentrate, or as the tetrahydrate Na 2 B 8 O 13 ·4H 2 O, 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]
One of the most common compounds used is disodium octaborate tetrahydrate Na 2 B 8 O 13 ·4H 2 O, commonly abbreviated DOT. Borate treated wood is of low toxicity to humans, and does not contain copper or other heavy metals.
Disodium octaborate tetrahydrate Na 2 B 8 O 13 ·4H 2 O (commonly abbreviated DOT) is used as a wood preservative or fungicide. Zinc borate is used as a flame retardant. Some borates with large anions and multiple cations, like K 2 Al 2 B 2 O 7 and Cs 3 Zn 6 B 9 O 21 have been considered for applications in nonlinear optics. [8]
Sodium borate is a generic name for any salt of sodium with an anion consisting of boron and oxygen, and possibly hydrogen, or any hydrate thereof. It can be seen as a hydrated sodium salt of the appropriate boroxy acid, although the latter may not be a stable compound.

The lethal dose is not necessarily the same for humans. On pesticide information websites it is listed as a non-lethal compound and of no hazardous concerns. [ citation needed ] Borax is absorbed poorly through intact skin, although fatalities have been recorded in persistent treatment of rashes and open wounds with boric acid-containing ...
A true tetrahydrate Na 2 H 4 B 2 O 8 ·4H 2 O, traditionally known as the "trihydrate", is also known but has no industrial significance. There is a CAS number for each of the three traditional "hydrates", the three "peroxyborate" versions of each (interpreted as a hydrogen peroxide adduct) and the poorly-defined "anhydrate" NaBO 3 , a total of ...
Disodium enneaborate is the traditional name for a salt of sodium, boron, oxygen, and hydrogen, with elemental formula Na 2 B 9 H 22 O 20 or Na 2 B 9 O 9 ·11H 2 O. It is the sodium borate with the highest boron/sodium ratio.
