In the realm of industrial chemicals, consistency and purity are non-negotiable. Whether you are formulating industrial detergents, treating boiler water, or using it as a chemical intermediate, the quality of your raw materials directly dictates the efficiency of your end product.
Disodium Phosphate (DSP) , particularly the Dodecahydrate form (Na2HPO4·12H2O), is a cornerstone chemical in many industrial sectors. As a professional supplier adhering to the HG/T 2965-2009 standard, we provide high-purity DSP that guarantees performance.

Disodium Phosphate (DSP), also known as Disodium Hydrogen Phosphate, is a highly soluble inorganic compound. Our industrial-grade product appears as white, odorless crystals. As a weak base (pH of 9.0±0.2 for a 10g/L solution), it acts as an excellent buffering agent and water softener.
Unlike other phosphates, the industrial grade focuses on cost-effectiveness for heavy-duty applications while strictly controlling harmful impurities like Arsenic (As) and Fluoride (F) to ensure operator safety.
Our DSP is manufactured under strict quality control to meet the Chinese National Standard HG/T 2965-2009. Below is the verified specification sheet for your technical evaluation:
| Parameter (Item) | Industrial Grade Standard (HG/T 2965-2009) | Our Guarantee |
|---|---|---|
| Main Content (as Na2HPO4·12H2O) | ≥ 97.0% | 97.0% - 98.5% |
| pH Value (10g/L solution) | 9.0 ± 0.2 | 9.0 |
| Sulfate (as SO4) | ≤ 0.7% | Compliant |
| Chloride (as Cl) | ≤ 0.05% | Compliant |
| Arsenic (as As) | ≤ 0.005% | Compliant |
| Fluoride (as F) | ≤ 0.05% | Compliant |
| Iron (as Fe) | ≤ 0.05% | Compliant |
| Water Insoluble | ≤ 0.05% | Compliant |
Note: The "Main Content" is calculated based on the dodecahydrate (Na2HPO4·12H2O) form.
Hard water causes scale buildup in pipelines and boilers, leading to energy loss. Our Industrial Grade DSP acts as a sequestrant. It precipitates calcium and magnesium ions, preventing them from forming scale. It is widely used in cooling towers, boiler feed water, and wastewater treatment facilities.
In the detergent industry, DSP serves as a powerful builder. It provides alkalinity, emulsifies oils, and suspends dirt particles, ensuring your cleaning products perform in hard water conditions without leaving residue on fabrics.
The alkaline buffer property (pH 9.0) makes it essential in the textile industry for dyeing and printing processes. It helps in the dissolution of dyes and ensures even color distribution.
We understand that B2B buyers need reliability. Every batch of our Industrial Grade Disodium Phosphate undergoes rigorous testing for:
Low Heavy Metals: Ensuring the Arsenic (As) content is strictly below 0.005%.
Low Chlorides: Preventing corrosion in high-temperature industrial equipment.
We provide Certificates of Analysis (COA) and Material Safety Data Sheets (MSDS) with every shipment.
We support flexible logistics solutions for our global partners:
Packaging: 25kg PP/PE bags, 50kg bags, or 1000kg Jumbo bags (customizable).
Storage: Store in a cool, dry, well-ventilated area. Keep away from acids and strong oxidizers.
Whether you need a reliable phosphate source for water softening or a buffering agent for industrial cleaning, our Industrial Grade Disodium Phosphate (DSP) is the optimal solution. With strict adherence to HG/T 2965-2009 and competitive pricing, we are your trusted partner in China.
