Sodium Chlorite Supplier in Malaysia
- Also known as
- NaClO2
- Chlorous Acid Sodium Salt
Sodium chlorite supplier for water-treatment, pulp, textile and industrial process buyers in Malaysia. Sodium chlorite (NaClO2) is the chlorite salt bought mainly as the precursor for on-site chlorine dioxide generation. It is not sodium chlorate, not sodium hypochlorite and not chlorine dioxide itself.
Traded forms are aqueous solution, usually named at about 25% or 31% w/w, and solid flake or powder at around 80% assay. Solution grades suit continuous generator feed and metered dosing, while solid grades suit plants that prepare their own solution on site. Strength and assay are confirmed against the specification you send.
Municipal and industrial water plants use sodium chlorite where chlorine dioxide is generated for oxidation, taste and odour work or biofilm control. Pulp, paper and textile mills use it in bleaching circuits, and food, beverage and oilfield operations specify it for process and sanitation water where ClO2 chemistry is named.
Send the required form, solution strength or solid assay, application, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation. Supply is subject to applicable requirements.

Sodium Chlorite grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Sodium chlorite solution 25% | pale yellowish aqueous solution | typically about 25% w/w | The concentration industrial buyers name most often for chlorine dioxide generator feed, metered dosing lines and process oxidation duties that specify a chlorite solution. | Confirm the required pack format with the quotation. |
| Sodium chlorite solution 31% | clear to pale yellowish aqueous solution | typically about 31% w/w | Higher solution strength for sites that prefer fewer deliveries and less storage volume for the same chlorine dioxide output. | Confirm the required pack format with the quotation. |
| Sodium chlorite flake | white to pale yellow flake | commonly around 80% | Solid grade for plants that make up their own solution on site rather than storing bulk liquid, and for buyers shipping over longer distances. | Confirm the required pack format with the quotation. |
| Sodium chlorite powder | white to pale yellow powder | commonly around 80% | Finer solid form for blending, faster dissolution and smaller batch preparation in bleaching and process work. | Confirm the required pack format with the quotation. |

Sodium Chlorite applications
Safety and handling
- Classification
- oxidising
Store sealed in a cool, dry, well-ventilated place away from acids, organic matter, reducing agents, combustibles and incompatible chemicals. Contact with acid liberates chlorine dioxide, so keep transfer equipment clean and dedicated. Handle as a strong oxidiser with suitable personal protection and follow the safety data for the quoted grade. Supply is subject to applicable requirements.
Common questions about sodium chlorite
Is sodium chlorite the same as sodium chlorate or sodium hypochlorite?
No. Sodium chlorite is NaClO2, sodium chlorate is NaClO3 and sodium hypochlorite is an aqueous NaOCl bleach solution. The three are separate products with different chemistry, handling and pricing, and the names are easy to mistype. Write sodium chlorite in full on the enquiry so the correct material is quoted.
Which sodium chlorite strength should I request, 25% or 31%?
Both are common industrial solution strengths. The 25% solution is the one most generator suppliers and process specifications name, while 31% moves more active chlorite per delivered tonne for sites that want less storage volume. Send the generator or dosing specification and we can quote against the strength it expects.
What is sodium chlorite used for in water treatment?
It is the usual feedstock for on-site chlorine dioxide generation, where the chlorite solution is reacted in a generator and the resulting ClO2 is dosed into the water or process stream. Buyers should state generator type, consumption rate and preferred solution strength when requesting a quote.
Should I order solution or solid sodium chlorite?
Solution grades suit continuous generator feed and metered dosing with no make-up step. Flake and powder grades suit sites that prepare their own solution, have limited liquid storage or ship over longer distances. Describe the handling method and dosing setup with the enquiry.
What specification details should I include with an enquiry?
Useful details are the target assay or solution strength, any limit on chlorate or sodium chloride content, the application, the quantity and the delivery location. If your plant works to a fixed specification sheet, attach it so the quotation can be matched against it.
What affects the price of sodium chlorite in Malaysia?
Form, solution strength or solid assay, order quantity, packing and delivery location are the main variables. Prices are quoted on enquiry with a stated validity period rather than published, because chlorine chemistry pricing moves with the market.
