What it is / When to use

Concentrated soluble boron for foliar and fertigation programs

SoluBor is a highly concentrated, fully water-soluble foliar boron raw material — disodium octaborate tetrahydrate (Na2B8O13·4H2O, CAS 12280-03-4) — supplying typically B2O3 67% and B 21% as a fine white powder at pH 6–8. RunziChem exports it for foliar boron correction and blend fortification.

  • What it is Disodium octaborate tetrahydrate (DOT), Na2B8O13·4H2O, CAS 12280-03-4, white free-flowing powder.
  • When to use Use it for concentrated foliar boron sprays, fertigation, and boron fortification of blended fertilizers, where fast, complete dissolution matters more than the lower cost of borax or boric acid.
  • Honesty note specifications are industry-typical values for evaluation; final values are confirmed per batch COA.

Applications

Where SoluBor (DOT) fits

Confirm crop, rate, compatibility, and local label requirements before application.

Concentrated boron source

Delivers a high boron load with typical B2O3 67% and B 21% in a single soluble powder.

Foliar spray

Fully soluble at near-neutral pH 6–8, so it mixes cleanly for concentrated foliar boron correction.

Fertigation & blends

Dissolves quickly for drip fertigation and boron fortification of blended water-soluble fertilizers.

Fast dissolution

Higher solubility than borax or boric acid reduces tank residue and nozzle clogging.

Compare with borax / boric acid

For lower-cost soil, blending, or granular routes compare Borax and Boric Acid; choose SoluBor when full solubility is required.

Batch documents

TDS, COA, and SDS support procurement and formulation review.

Buyer FAQ

SoluBor (DOT) questions

How does SoluBor (DOT) compare with borax and boric acid?
SoluBor is disodium octaborate tetrahydrate (Na2B8O13·4H2O), a highly concentrated boron source carrying typically B2O3 67% and B 21%, and it is far more water-soluble than borax (B 11–15%) or boric acid (B 17%). Choose SoluBor when you need a fully soluble product for concentrated foliar sprays and fertigation; choose borax or boric acid for lower-cost soil, blending, or granular routes.
Why is SoluBor preferred for foliar boron programs?
SoluBor dissolves quickly and completely to a near-neutral pH of about 6–8, so it mixes cleanly in spray tanks without clogging nozzles. With B 21% it delivers a high boron load per litre, which makes it efficient for correcting boron deficiency on crops such as oilseed rape, cotton, fruit, and vegetables. Confirm rate, timing, and tank-mix compatibility before application.
What packaging and documents does RunziChem provide for SoluBor?
RunziChem exports SoluBor in 25 kg / 50 kg bags, jumbo bags (1,250 kg), and custom packaging on request. TDS, the current batch COA, and SDS are available on request so buyers can verify the boron content and specification before order confirmation.
Are the boron values for SoluBor guaranteed?
No. The figures shown for SoluBor, such as B2O3 67% and B 21%, are industry-typical values for buyer screening. The current batch certificate of analysis (COA) confirms the final boron content, moisture, and appearance for the specific lot you receive.
