What is Disodium Octaborate

disodium-octaborate-tetrahydrate-powder

Disodium octaborate is also known as aquabor/boron sodium oxide or sodium octaborate with formula of Na2B8O13.4H2O. Disodium octaborate is a white and odorless powder which contains the basic elements of boron and oxygen. The most common application is for pest control products. In nature, disodium octaborate occurs as alkaline borate.

Manufacturing Process

disodium-octaborate-production-process

Disodium octaborate is produced using one-step boric acid method, which uses boric-acid, sodium-containing chemical product, water, and an impurity removal agent. All these materials are placed in a reactor, stirred, and heated at 60-120 degree celcius under a heat preservation condition for 0.5-2 hour. After the reaction, the product is filtered to obtain the product. The filtrate is dried at 90-200 degree celcius and the product after the drying is the disodium octaborate with low impurity content. The impurity is removed using hydrogen peroxide, concentrated aqueous ammonia, ammonium carbonate, ammonium bicarbonate, and activated carbon.

The Uses of Disodium Octaborate Tetrahydrate

Disodium octaborate tetrahydrate is Disodium Octaborate Tetrahydrate (or DOT) is a white, odorless, powdered substance containing the basic elements of boron and oxygen. Disodium Octaborate Tetrahydrate is not flammable and presents little or no hazard (to humans).

Pest Control

Disodium Octaborate Tetrahydrate is one of a family of borate compounds (containing boron and oxygen), which are considered absolutely toxic to insects. Borate compounds like Disodium Octaborate Tetrahydrate utilize a stop-feed mode of action, means that the active ingredient DOT disrupts the enzyme and digestive systems of the insect. In treatment of wood decaying insects like termites or carpenter ants, DOT prevents these pests from being able to digest the wood that they depend on for survival. Disodium octaborate is also effective against fungi and algae (fungicide), molluscs and mildew.

Toxicity Summary

The inorganic borates display low acute toxicity. They are either not irritant or mild skin and eye irritants. They are not skin sensitisers, nor are they mutagenic or carcinogenic. The most sensitive endpoints of toxicity are considered to be effects on the reproductive organs, fertility in males, and developmental effects. The doses that cause these effects are far higher than any levels to which the human population could be exposed
