Product Overview

What is Disodium Octaborate Pentahydrate?

Disodium Octaborate Pentahydrate, commonly shortened to DOT, is a refined sodium borate made by reacting borax with boric acid. It is a white, odourless, free-flowing powder or granule carrying about 67% B₂O₃ — roughly 20.9% elemental boron — which is the highest boron content of the widely traded commercial borates.

Its defining property is solubility. DOT dissolves far more readily and in far higher concentration than borax decahydrate, which lets formulators make strong boron solutions for foliar sprays, fertigation and timber diffusion treatment without heating.

Agriculture and wood protection are the main uses. In agriculture DOT corrects boron deficiency in crops; in timber it diffuses into wood to protect against fungal decay and insect attack. Chelora Chemicals UAE supplies agricultural and technical DOT grades across the UAE and wider GCC.

FAQ

Frequently Asked Questions — DOT UAE

What is Disodium Octaborate Pentahydrate used for?

DOT is used as a boron micronutrient in foliar sprays, fertigation and fertiliser blends, as a timber preservative against fungal decay and insects, as a fire retardant in cellulose insulation, and in borate-based pest control formulations.

What is the CAS number of DOT?

The CAS number for Disodium Octaborate Pentahydrate is 12280-03-4, with the formula Na₂B₈O₁₃·4H₂O. It is traded under HS code 2840.20.

How does DOT compare with borax decahydrate?

DOT carries roughly 20.9% boron against about 11.3% for borax decahydrate, and it dissolves far faster and to a much higher concentration in cold water. That makes it the preferred choice for spray tanks, fertigation lines and timber diffusion treatment.

Why is DOT used to protect timber?

Because it dissolves into a concentrated, low-viscosity solution, DOT diffuses deep into wet or green timber rather than sitting on the surface. Once in place it resists decay fungi, termites and wood-boring beetles without colouring or corroding the wood.

Who supplies Disodium Octaborate Pentahydrate in the UAE?

Chelora Chemicals UAE is a dedicated DOT supplier serving all seven UAE emirates. We stock agricultural and technical grades in powder and granular form, serving fertiliser blenders, timber treatment plants and formulators across Dubai, Abu Dhabi, Sharjah, Ajman, Ras Al Khaimah, Fujairah and Umm Al Quwain.

Do you deliver DOT to Dubai, Abu Dhabi and Sharjah?

Yes. Chelora Chemicals UAE delivers DOT to all seven UAE emirates — Dubai (including Jebel Ali FZ, Al Quoz and DIP), Abu Dhabi (Musaffah, ICAD, KIZAD), Sharjah (SAIF Zone, Hamriyah FZ), Ajman, Ras Al Khaimah, Fujairah and Umm Al Quwain — as well as to Saudi Arabia, Qatar, Kuwait, Bahrain, Oman and other GCC countries.

Is DOT hazardous?

DOT is classified in the EU as toxic for reproduction (Category 1B, H360FD) and appears on the REACH Candidate List. It is not flammable or oxidising and is not regulated for transport, but dust should be controlled and suitable PPE worn. Always consult the batch-specific SDS.

What packaging is available for DOT?

Chelora Chemicals UAE supplies DOT in 25 kg lined bags (standard use), 1 MT jumbo bags (blenders and treatment plants), palletised container loads (export parcels) and truck delivery from our UAE warehouse.

Can DOT be exported from the UAE?
