1. Product & Identification Information

2. Physical & Chemical Properties

3. Applications

Dequest 2060 / DTPMPA is widely used across industries due to its excellent scale inhibition and corrosion inhibition properties.

Main Application Areas:

• Water Treatment Systems: Scale and corrosion inhibitor in cooling towers, boiler water, geothermal water treatment, industrial and municipal cleaning waters. Performs effectively in alkaline environments without requiring pH adjustment.

• Detergents & Cleaning Products: Chelating agent and anti-scale agent. Especially used in automatic dishwasher detergents and industrial cleaners.

• Oil & Gas Industry: Scale and corrosion control in oilfield reinjection waters, waters containing high barium carbonate, and downhole equipment.

• Pulp & Textile Industry: Peroxide bleaching stabilizer, oxygen delignification stabilizer, and chelating agent in textile printing/dyeing processes.

• Other Industries:

  • Cosmetics and personal care products

  • Carrier for micronutrients in fertilizers

  • Concrete admixture

  • Electroplating and metal acid cleaning

  • Mining and ore processing

4. Superior Features & Advantages

• High Thermal Stability & Performance: DTPMPA provides superior scale and corrosion inhibition compared to other organophosphonates at high alkalinity and temperatures up to 210°C.

• Broad-Spectrum Scale Prevention: Effectively prevents formation of calcium carbonate (CaCO₃), calcium sulfate (CaSO₄), and especially the hard-to-dissolve barium sulfate (BaSO₄).

• Strong Chelating & Dispersing Effect: A powerful multidentate chelating agent that binds metal ions, preventing unwanted reactions and precipitation.

• Corrosion Inhibitor: Provides effective corrosion protection on metals such as steel, copper, and alloy steels.

• Reduces Need for Separate Dispersants: Even when used alone, it minimizes scale formation without requiring an additional dispersant.

• Environmentally Friendly Profile: Non‑toxic structure and biodegradable properties make this phosphonate generally considered environmentally compatible.

5. Usage Instructions & Dosage

Recommended concentrations vary depending on the application. General guidelines are as follows:

Note: The optimal dosage should be determined by laboratory tests based on water analysis and system operating conditions.

6. Safety & Handling Information

• Hazard Classification: The product is acidic. Avoid contact with skin and eyes.

• First Aid: In case of eye or skin contact, wash with plenty of water for at least 15 minutes. Seek medical attention.

• Personal Protective Equipment (PPE): Wear protective gloves, goggles, and appropriate work clothing during handling.

• Transport Class (RIDADR): UN

• Storage: Keep in original closed containers in a cool, dry, well-ventilated place away from direct sunlight. Protect from freezing.

• Shelf Life: 12 months from date of manufacture when stored under appropriate conditions.

• Packaging Options:

  • 200 L HDPE drum or 1000 L IBC tank

  • 25 kg, 30 kg, or 250 kg plastic drums

7. Regulatory Information

• EINECS (Europe): 244-751-4

• TSCA (USA): Listed

• AICS (Australia): Listed

• ECL (Korea): Listed

• PICCS (Philippines): Listed

• DSL (Canada): Listed

8. Product Variants (Sodium Salts)

Since the acid form of DTPMPA has limited solubility in water, it is commercially available mainly as sodium salts with different neutralization degrees. CAS 22042-96-2 indicated by the user refers to one of these salt forms.

9. Compatibility

Dequest 2060 / DTPMPA is compatible with the following chemicals:

• Polycarboxylates (e.g., acrylic acid copolymers)

• Other organophosphonates (e.g., ATMP, HEDP)

• Zinc salts

• Polyphosphates

Sectoral Compatibility Table & Recommended Usage Rates

DTPMPA is widely used across industries due to its strong chelating and scale inhibition properties. The table below details the key sectors and their typical dosages.

Important Note: The values above are general guidelines. The optimal dosage must be determined by laboratory tests (jar tests, etc.) based on water chemistry and system operating conditions.

Alternatives to DTPMPA

While DTPMPA offers excellent performance, other organophosphonates may be preferred for specific conditions.
