DTPMP 50%ZEELCHEM™ 131 · Manufacturer & Supplier
DTPMP 50% (diethylenetriamine penta(methylene phosphonic acid)) is the industry-standard phosphonate for barium and strontium sulfate scale. ZEELCHEM™ 131 works as a threshold inhibitor at just 2–5 ppm, protects downhole tubing and RO membranes, and stabilizes hydrogen peroxide in pulp and textile bleaching.

How DTPMP 50% Works
Sulfate threshold inhibition
Blocks BaSO₄ and SrSO₄ crystal growth at 2–5 ppm. These deposits are virtually acid-insoluble once formed.
Multi-dentate chelation
Five phosphonate groups sequester Fe, Mn and Cu ions.
Peroxide stabilization
Removing catalytic metals stops H₂O₂ from decomposing in bleach baths.
Key Benefits
- Industry standard for barium and strontium sulfate scale
- Higher calcium tolerance than standard phosphonates, pH 6.5–10.0
- Stable in high-salinity brines
- Stronger H₂O₂ stabilization for higher bleaching brightness
- Removed in ETPs by adsorption onto sludge and coagulants

What is DTPMP 50% and what is it best for?
A pentaphosphonic acid chelating scale inhibitor, widely used as the standard for barium and strontium sulfate scale prevention.
What is the DTPMP dosage in oilfields and RO?
10–30 ppm active for oilfield downhole squeeze and produced water, and 2–6 ppm active for high-sulfate RO feedwater.
Why is DTPMP used in pulp and paper bleaching?
Its multi-dentate chelation stabilizes H₂O₂ at 1.0–2.5 kg/ton pulp, raising brightness and reducing chemical use.
What is the active concentration of ZEELCHEM™ 131?
48–52% active DTPMPA, specific gravity 1.38–1.44 g/cm³, with low phosphorous acid impurities.
How does DTPMP perform in high-hardness water?
It tolerates calcium better than standard phosphonates, preventing CaCO₃ and CaSO₄ precipitation from pH 6.5 to 10.0.
Why is barium sulfate scale so serious?
BaSO₄ is virtually insoluble in acid and cannot be removed mechanically once deposited in tubing or membranes, so prevention is essential.
What packaging is available?
65 kg carboys, 250 kg virgin HDPE drums, 1,250 kg IBC totes and bulk tankers.
What is the shelf life?
24 months in sealed HDPE containers, in a cool, ventilated warehouse at 5–40 °C.
What PPE is recommended?
Chemical goggles, a face shield, heavy-duty nitrile gloves and protective workwear.
Do you provide COA and MSDS with every batch?
Yes. Every ZEELCHEM™ 131 consignment ships with a batch Certificate of Analysis, and the TDS and 16-section GHS Safety Data Sheet are available on request.
