Applications
Buyers rarely start from a product name. They start from a process and a regulation. These are the fields we supply most often, and what each one actually needs.
Activated by acid, sodium chlorite generates high-purity chlorine dioxide. High disinfection efficiency with minimal disinfection by-products is why waterworks use it rather than chlorine.
Our sodium chlorite is on the official US inventory of drinking water treatment chemicals.
Minimal fibre damage with mild, long-lasting bleaching — its main advantage over chlorine bleaches in dyeing. In pulp bleaching it substitutes for chlorine-containing bleaches.
This is where the environmental upgrade argument for a mill usually starts.
Chlorine dioxide diffuses and penetrates well, reaching crevices and dead spaces inside equipment, and is low in corrosiveness to medical devices. Chlorite-loaded nanofibres release ClO₂ below pH 7.
Tell us the device or formulation — the impurity spec matters more than the assay here.
Sterilisation and fresh-keeping. Used on produce, in processing water and in aquaculture handling.
This field must comply strictly with food-grade standards. Confirm the destination country's rules with us before ordering.
Acts as a strong oxidant, converting insoluble nitric oxide into soluble higher-valence nitrogen oxides such as NO₂, which the desulfurisation system then removes.
Usually a continuous-volume contract rather than spot purchasing.
Chloroethylene carbonate is used as an electrolyte additive in lithium-ion cells, improving cycle performance and service life. High-purity grade doubles as a flame-retardant additive.
A different product line — see chloroethylene carbonate.
Other fields
Environmental deodorisation and air purification, where it oxidises hydrogen sulfide and ammonia; leather processing, where it removes impurities and grease to improve whiteness; and as an oxidant in pharmaceutical, pesticide and fine-chemical synthesis, plus precision surface treatment of metals.
How to specify
Answer these four in your first message and we can come back with a grade, the applicable certificates and a price — instead of a reply that asks you the same four questions.
Drinking water, textile, pulp, food or flue gas. The application decides the grade, and the grade decides the price and the paperwork. Nothing can be quoted before this.
NSF covers North America, REACH covers the EU. Neither transfers to the other. Tell us the destination before asking for certificates.
Solid is 50 kg drums; liquid ships in PVC drums and IBC totes. Concentration is made to your specification — freight cost often decides this more than process does.
A trial drum, a container, or a scheduled annual contract are three different conversations about price and lead time.
Before you ask
Answered with the certificate reference or the standard number wherever one exists. Where a figure depends on your batch or your market, we say so instead of publishing a number that will not match what ships.
Mainly as the precursor for chlorine dioxide. Activated by acid it generates high-purity chlorine dioxide for drinking water and municipal treatment, where it produces far fewer disinfection by-products than chlorine. It is also used for textile and pulp bleaching, medical and device disinfection, food processing and aquaculture, and as an oxidant in flue gas denitrification.
They are different compounds with different chemistry. Sodium chlorite is NaClO₂ (CAS 7758-19-2); sodium hypochlorite is NaClO, the active ingredient in household bleach. Sodium chlorite is used chiefly to generate chlorine dioxide, which penetrates better, works across a wider pH range and leaves fewer chlorinated by-products. They are not interchangeable — check which one your process specifies before ordering.
Our sodium chlorite is listed on the official United States inventory of drinking water treatment chemicals under NSF International, and is registered under EU REACH for the European market. NSF covers North America and REACH covers the EU — neither transfers to the other, so tell us the destination market before asking for certificates.
HG/T 3250-2023, the Chinese industry standard for industrial sodium chlorite. Gaoyuan organised and compiled that 2023 revision, after taking part in drafting the 2010 edition. If a supplier still quotes HG/T 3250-2010, they are citing a superseded edition.
UN 1908, as a solution. It must not be transported together with acids or reducing substances, and dry powder extinguishers are prohibited — use water spray or sand. We supply the SDS on request; tell us the destination and mode of transport so the documentation matches your route.
Solid ships in iron drums with a plastic inner liner at 50 kg net per drum. Liquid ships in IBC totes at 1,250 kg net, 200 L polyethylene drums at 250 kg net, or 20 L polyethylene drums at 25 kg net. Customised packaging and concentration are available on request.
ISO 9001 (ref. 10423Q01965R1M), ISO 14001 (ref. 10423E01271R1M) and ISO 45001 (ref. 10423S01149R0M), all issued by Shandong Seatone International Certification Co., Ltd. under CNAS accreditation. The certificate scans are published on our quality page so the references can be checked with the certification body directly.
We issue a certificate of analysis against the batch you are quoted, rather than publishing a single headline figure that may not match what ships. Tell us the grade and end use and we will send the COA and SDS for the relevant batch. The application decides the grade, and the grade decides both the specification and the paperwork.
Yes. Chloroethylene carbonate (CAS 3967-54-2, C₃H₃ClO₃) is made on a dedicated line commissioned in 2022, with 40,000 t/y capacity. It is used as a lithium-ion electrolyte additive to improve cycle performance and service life, and the high-purity grade also serves as a flame-retardant additive.
