If you’ve ever scanned the ingredient list on a shampoo bottle, you’ve probably spotted sodium sulfate and wondered, what is sodium sulfate in shampoo and why is it so common in personal care products? While that question often arises from everyday consumers, industrial procurement professionals face a parallel challenge: distinguishing between similar-sounding chemicals like sodium sulfate and sodium sulfite. The latter, sodium sulfite (Na₂SO₃), may not belong in your hair care routine, but it is indispensable in boiler water treatment, pulp processing, and textile manufacturing. This guide demystifies the sulfate‑sulfite confusion, dives into sodium sulfite’s formula compound, explores bulk price dynamics, and shows why partnering with a reliable sodium sulfite manufacturer like Hailei Fine Chemical can elevate your supply chain resilience.
First, let’s answer the consumer‑side question directly. Sodium sulfate (Na₂SO₄) is an inorganic salt that functions primarily as a thickening agent and detergent booster in shampoos and liquid soaps. It increases viscosity, giving the product a rich, creamy feel, and helps surfactants lather more effectively. In small concentrations it is generally recognized as safe. Chemically, sodium sulfate is highly soluble in water, pH‑neutral, and non‑reactive during typical shampoo formulation.
From a sodium sulfate chemical properties standpoint, it appears as a white crystalline solid, anhydrous (thenardite) or decahydrate (Glauber’s salt), with a molecular weight of 142.04 g/mol for the anhydrous form. Its industrial‑scale production often stems from natural sources or as a by‑product of rayon and HCI manufacturing. But here’s the crucial off‑ramp: the sodium sulfate used in shampoos serves entirely different chemical functions than sodium sulfite, a reducing agent that powers heavy‑duty industrial processes. Confusing the two can lead to costly procurement mistakes.
While both compounds share the “sodium” cation, their anions—sulfate (SO₄²⁻) and sulfite (SO₃²⁻)—dictate radically different redox behaviors. Sodium sulfate is already fully oxidized and acts as an inert filler or builder. Sodium sulfite, on the other hand, is a strong reducing agent that readily consumes dissolved oxygen, making it invaluable as an oxygen scavenger in boiler systems. The distinction is non‑negotiable; substituting one for the other would cripple a boiler’s corrosion protection program or fail to control residual chlorine in textile bleaching.
Industrial buyers must also note purity requirements. Cosmetic‑grade sodium sulfate rarely exceeds 99% and may contain additives permitted for personal care. Technical‑grade sodium sulfite for boiler water treatment demands 96–98% purity (anhydrous) or the heptahydrate equivalent, with strict limits on heavy metals and insolubles. Hailei’s sodium sulfite meets these specifications consistently, giving power plant operators and pulp mill engineers the reliability they need.
At the heart of every procurement conversation lies the sodium sulfite formula compound. The anhydrous material is represented by Na₂SO₃, a white granular powder with a molecular weight of 126.04 g/mol. When crystallized from aqueous solution, it forms the heptahydrate Na₂SO₃·7H₂O, which is a colorless crystalline solid. Both forms dissolve readily in water, producing sulfite ions (SO₃²⁻) that actively scavenge oxygen through the reaction: 2SO₃²⁻ + O₂ → 2SO₄²⁻. This stoichiometry is the bedrock of its use in boiler feedwater treatment, where every 1 ppm of dissolved oxygen consumes roughly 7.9 ppm of anhydrous sodium sulfite.
Storage and handling also hinge on the compound’s properties. Anhydrous sodium sulfite is hygroscopic and gradually oxidizes to sulfate if exposed to moist air. Smart buyers specify sealed, moisture‑resistant packaging—typically 25 kg or 1000 kg big bags—and confirm that the sodium sulfite manufacturer includes oxygen‑barrier liners. Hailei Chemical packages sodium sulfite in multilayer PE‑lined kraft bags or FIBCs, ensuring the product’s reducing power remains intact throughout the logistics chain.
While consumers may ask “what is sodium sulfate in shampoo,” industrial engineers rely on sodium sulfite to solve critical operational challenges. Below are the key application verticals where Hailei’s sodium sulfite delivers measurable performance.
The single largest application for sodium sulfite is the removal of dissolved oxygen from boiler feedwater. Even trace oxygen levels (as low as 5 ppb) can cause pitting corrosion in carbon steel tubes, leading to unplanned downtime and expensive repairs. Sodium sulfite reacts rapidly with oxygen at boiler operating temperatures (>90 °C), often catalyzed by trace metals, to form harmless sodium sulfate. This treatment is favored by many power plants because it is cost‑effective, easy to monitor via sulfite residual testing, and compatible with most boiler chemistries. Hailei supplies anhydrous sodium sulfite (purity ≥96%) tailored to high‑pressure boiler specifications, often accompanied by a Certificate of Analysis that certifies sulfite content, chloride limits, and heavy metal thresholds.
In the pulp and paper industry, sodium sulfite serves as a cooking liquor component in the neutral sulfite semi‑chemical (NSSC) process or as a brightening agent in mechanical pulping. It selectively sulfonates lignin while minimizing carbohydrate degradation, yielding high‑yield, high‑strength pulp used for corrugating medium and linerboard. A consistent particle size and rapid dissolution rate are critical for pulping uniformity. Hailei’s technical‑grade sodium sulfite is designed to meet the dissolution kinetics demanded by continuous pulp digesters, reducing unreacted chemical carry‑over and ensuring predictable pulp brightness.
After hydrogen peroxide bleaching, cotton and blended fabrics carry residual oxidizers that can cause yellowing and uneven dye uptake. Sodium sulfite acts as a gentle, easily controllable anti‑chlor or neutralizer, converting hypochlorite to chloride and decomposing excess peroxide. Mills using automated dispensing systems prefer sodium sulfite over sulfur dioxide gas because it can be dosed as a stable liquid solution. The low toxicity and absence of sulfurous gas drag‑out make it a safer, more sustainable choice for modern finishing plants. Hailei can supply sodium sulfite in both anhydrous and heptahydrate forms, allowing textile chemists to select the grade that best integrates with their process water temperature and solubility requirements.
Though niche, sodium sulfite remains a cornerstone in black‑and‑white photographic developers, where it protects developing agents from oxidation and prolongs solution life. In leather processing, sodium sulfite assists in loosening hair follicles during dehairing of hides, reducing the reliance on harsh sulfides. These specialized applications demand high‑purity, low‑iron sodium sulfite to avoid staining and unwanted chemical reactions. Hailei’s production process, which uses high‑purity soda ash and food‑grade sulfur dioxide scrubber technology, consistently achieves iron levels below 0.002%, meeting even the exacting photographic‑grade specifications.
When evaluating sodium sulfite bulk price, procurement managers look beyond the per‑ton figure. Raw material volatility (especially sulfur and soda ash), energy costs, and freight charges dominate pricing. In 2025, FOB China pricing for technical‑grade anhydrous sodium sulfite (96‑98%) typically ranges between $280 and $380 per metric ton, depending on order volume, packaging, and purity premium. Heptahydrate grades, being less concentrated, often trade at a lower cost per kilogram of active sulfite, but the higher shipping weight must be factored into total landed cost.
Other price drivers include:
Requesting a detailed quotation that breaks down these variables is essential. Hailei’s dedicated export team provides transparent, all‑inclusive offers, so buyers can accurately model their cost‑in‑use.
As a leading sodium sulfite manufacturer based in Weifang, China, Hailei Fine Chemical has supplied technical‑grade sulfites to global markets for over a decade.

Buyers consistently cite these advantages:
Integrate Hailei into your approved vendor list and gain a partner who treats your boiler water, pulp, or textile chemicals as critical inputs, not commodities.
Can sodium sulfite be used to neutralize chlorine in wastewater?
Yes, sodium sulfite rapidly reacts with free chlorine and hypochlorite, making it an effective dechlorination agent for process water or effluent streams prior to discharge. It is often preferred over sulfur dioxide gas for safety reasons.
What is the shelf life of anhydrous sodium sulfite?
When stored in original, unopened packaging in a cool, dry environment, anhydrous sodium sulfite has a recommended shelf life of 12 months. Significant caking or moisture absorption indicates degradation; periodic sulfite content testing is advised for stocks held near the expiry.
How does sodium sulfite bulk price compare to catalyzed sulfite?
Catalyzed sodium sulfite (pre‑blended with cobalt or other catalysts) commands a premium of 5‑15% over standard grades. For systems operating below 80 °C, the catalyzed version can improve oxygen removal kinetics, but the additional cost must be balanced against fuel savings and equipment protection.
Is sodium sulfite hazardous?
Sodium sulfite is classified as a mild irritant to skin and eyes. It releases sulfur dioxide gas when contacted with strong acids. Proper PPE (gloves, goggles) should be worn, and storage areas must be dry and well‑ventilated. It is not classified as a persistent environmental toxin, and Hailei’s product complies with all relevant GHS labeling requirements.

Securing a competitive sodium sulfite bulk price is a critical concern for power plants, pulp and paper mills, textiles finishers, and leather processors. As a high-consumption oxygen scavenger and process chemical, sodium sulfite (Na2SO3) directly impacts operational margins. This guide breaks down the pricing landscape, from raw material influences and purity specifications to logistics optimization and supplier evaluation, enabling you to negotiate better contracts and avoid costly supply disruptions.
Whether you are sourcing anhydrous or heptahydrate grades, understanding the interplay between global sulfur markets, bulk density, and manufacturer capabilities will help you build a resilient, cost-efficient supply chain. Hailei Chemical, as a dedicated sodium sulfite manufacturer, brings transparency to these factors to support your procurement decisions.
The sodium sulfite bulk price is far from static. It responds to upstream chemical costs, energy dynamics, and regional supply-demand balances. By monitoring these drivers, procurement teams can anticipate price movements and time bulk purchases strategically.
Sodium sulfite is industrially produced by reacting soda ash (sodium carbonate) with sulfur dioxide. Therefore, fluctuations in soda ash and SO2 markets directly feed into finished product pricing. Key cost components include:
Sodium sulfite production involves exothermic reactions and crystallization, but drying and evaporation steps are energy-intensive. Locations with competitive electricity, steam, or coal costs—such as Chinese industrial zones—can maintain lower operating expenses. A sodium sulfite manufacturer with integrated cogeneration or waste-heat recovery systems can offer more stable bulk pricing.
You will typically encounter two commercial forms, and their cost structures differ significantly:
Standard industrial grades run 96% purity, which suffices for most boiler water treatment and textile bleaching neutralization. Higher 98% grades, needed for fine chemical or photographic applications, undergo additional purification steps, pushing the sodium sulfite bulk price up by 5–15%. Always specify your exact application to avoid over-specification that inflates cost without functional benefit. Hailei Chemical produces both grades, allowing you to balance performance and budget.
Ocean freight rates, container availability, and port congestion can add USD 50–150 per tonne to the CIF price. When comparing quotes, always request FOB and CIF breakdowns. A reliable sodium sulfite manufacturer will help you optimize shipment sizes—full container load (FCL) of 20- or 40-foot containers, or break-bulk vessels for ultra-large orders—to minimize unit freight costs.
Partnering with a manufacturer that combines process expertise, quality consistency, and logistics flexibility is the cornerstone of controlling your sodium sulfite bulk price over time. Here’s what to look for.
China remains a dominant force in the sodium sulfite market due to vertical integration with soda ash supply and large-scale sulfur-burning capacity. Manufacturers in Shandong province, such as Hailei Chemical, benefit from proximity to raw materials, competitive engineering talent, and efficient port access. By sourcing directly from the factory, you eliminate intermediate trader markups, securing a transparent sodium sulfite bulk price tied directly to production economics.

Sodium sulfite bulk density is a technical parameter that often gets overlooked during price negotiations, yet it significantly influences freight utilization and storage footprint. Selecting the right physical form can lower your per-kilogram delivered cost.
If your plant handles anhydrous material but your supplier offers a cheaper heptahydrate EXW price, the landed cost might actually favor anhydrous once ocean freight, inland trucking, and storage are factored in. Always calculate the price per kilogram of active Na2SO3 delivered rather than comparing invoice prices. At Hailei, we provide detailed technical datasheets that include bulk density and recommended container loading plans so you can model your total cost of ownership accurately.
The chemical supply chain often clusters related products. Sodium sulfate suppliers frequently handle sodium sulfite as part of their portfolio, offering consolidated purchasing advantages. While the two chemicals serve distinct functions—sodium sulfate (Na2SO4) is a byproduct of rayon and detergent manufacturing, used in glass and textile dyeing—they share logistical and commercial expertise.
Many buyers ask, “What is sodium sulfate formula?” It’s Na2SO4, and although it is chemically different from Na2SO3, sourcing both from a single sodium sulfite manufacturer that also trades in sulfate brings several benefits:
When evaluating sodium sulfate suppliers for your sulfite needs, verify that they operate dedicated sulfite production lines—not just blending or repackaging. Hailei Chemical is a direct manufacturer of sodium sulfite, ensuring full traceability and consistent quality, while also offering complementary chemicals to streamline your sourcing process.
Beyond comparing EXW quotes, adopt a total-value mindset to drive down your effective sodium sulfite bulk price:
For standard 96% anhydrous grade, factory lead time is usually 10–15 working days after receipt of LC or deposit, plus transit time. Heptahydrate may have shorter production cycles. During peak demand months (autumn boiler maintenance seasons), lead times can extend, so forward planning is advised.
Store in a cool, dry, well-ventilated area away from acids and oxidizers. Anhydrous sodium sulfite gradually oxidizes to sodium sulfate if exposed to moist air, reducing its oxygen-scavenging efficiency. Maintain sealed original packaging and use first-in, first-out inventory rotation. Shelf life is typically 12 months from production date under correct conditions.
Yes, many suppliers including Hailei Chemical offer quarterly or semi-annual fixed pricing, provided the volume is within agreed ranges. Longer fixed-price periods may include a raw material escalation clause to protect both parties. Contact us to discuss a pricing mechanism that fits your budget cycle.
Standard export documents: commercial invoice, packing list, bill of lading, certificate of analysis (COA), certificate of origin (Form E or Form F as applicable), and MSDS. We can also provide third-party inspection certificates (SGS, Intertek) upon request to ensure the shipment meets all agreed specifications.
Securing a stable, competitive sodium sulfite bulk price requires more than a quick spot quote—it demands a supply partner who understands your process, your logistics, and your market. Hailei Chemical combines large-scale manufacturing with technical support and flexible commercial terms to help you achieve your cost and performance targets.

When procurement managers and chemical engineers search “what is sodium sulfate in shampoo,” they often encounter a mix of consumer-focused information about hair care ingredients. Yet, for industrial buyers, this query opens a door to a critical distinction: sodium sulfate (Na2SO4), the shampoo thickener, and sodium sulfite (Na2SO3), an essential oxygen scavenger and reducing agent, are two entirely different compounds—each with unique chemistry, applications, and supply chains. At Weifang Hailei Fine Chemical Co., Ltd., we specialize in high-purity sodium sulfite for demanding industrial processes, not the cosmetic grade sulfate found in personal care. Understanding the difference can prevent costly purchasing errors and ensure you source the right chemical for your boiler water treatment, pulp processing, or textile bleaching line.
The question itself reflects a common confusion. Sodium sulfate (Na2SO4), often sold as Glauber’s salt or sulfate of soda, is widely used in shampoo formulations. Its primary role is as a thickener and viscosity modifier: it reduces the electrostatic repulsion between surfactant micelles, allowing shampoos to achieve that rich, gel-like consistency consumers expect. It also acts as a processing aid, making liquid detergents easier to handle. However, sodium sulfate is chemically inert in most personal care contexts—it doesn’t lather, clean, or condition hair. Instead, it’s a functional additive, derived either from natural mineral sources or as a byproduct of chemical manufacturing like rayon production. For industrial buyers, sodium sulfate typically appears in powder or granular form with purity grades of 92–99% depending on the end use, from detergents to glassmaking.
To appreciate the distinction, let’s briefly review sodium sulfate chemical properties. Na2SO4 has a molar mass of 142.04 g/mol, a neutral pH (5–7 in aqueous solution), and high thermal stability (melting point 884°C). It is moderately soluble in water (about 28 g/100 mL at 25°C), and its solubility curve exhibits a maximum near 33°C—important when specifying hydrate forms. Available as anhydrous and decahydrate (Glauber’s salt), it is used in textiles for leveling dyes, in kraft pulp cooking, and as a filler in powdered detergents. None of these applications involve oxygen scavenging or strong reducing power, which is where sodium sulfite enters the picture.
Whenever a buyer mixes up sodium sulfate and sodium sulfite, the consequences can be severe. The sodium sulfite formula compound is Na2SO3, a white crystalline solid that acts as a potent oxygen scavenger and mild reducing agent. In contrast to sulfate’s SO4²⁻ anion, sulfite’s SO3²⁻ anion possesses a lone pair and can readily oxidize to sulfate, making it ideal for removing dissolved oxygen from boiler feedwater, preventing corrosion in power plants. At Hailei, we manufacture both anhydrous sodium sulfite (96–98% purity) and the heptahydrate form (Na2SO3·7H2O), each tailored to specific process temperatures and dosing systems. The anhydrous material is favored for high-temperature boiler treatments due to its stability, while the heptahydrate is easier to handle in ambient conditions and dissolves rapidly.
Sodium sulfite’s chemical properties are distinctly different: it has a molar mass of 126.04 g/mol, a melting point of 33.4°C for the heptahydrate (which decomposes upon further heating), and a pH of 9–10 in solution, indicating an alkaline reaction. This alkalinity is beneficial in boiler water treatment to maintain passivation layers on steel surfaces. The reducing power is quantified by its sulfite content (as SO3²⁻) and the rate of oxygen uptake—critical performance metrics for our industrial clients.
Imagine ordering “sodium sulfate” for your power plant’s deaerator line. At best, the inert salt would do nothing, leaving dissolved oxygen to corrode boiler tubes and cause costly shutdowns. At worst, a casual supplier might send a low-grade sulfate mislabeled as sulfite, leading to catastrophic system failures. We see this confusion often in international procurement, especially where English is not the first language. The similarity in names masks a fundamental difference in function: sodium sulfate is a filler, sodium sulfite is a scavenger. By clarifying “what is sodium sulfate in shampoo” and why it’s irrelevant to your plant, you protect operations and budgets.
In high-pressure boilers, dissolved oxygen must be kept below 7 ppb to avoid pitting corrosion. Catalyzed sodium sulfite reacts rapidly with oxygen to form sodium sulfate (the same product that ends up in shampoo, ironically), but in this context, it’s a controlled reaction that safeguards millions of dollars in infrastructure. Hailei’s sodium sulfite is designed for low-impurity, high-reactivity performance, capable of achieving residual sulfite levels of 20–40 ppm in boiler water—meeting standards like ASME Consensus on Water Chemistry. We provide customized granular sizes to suit volumetric or slurry feed systems, ensuring our sodium sulfite integrates seamlessly into your plant’s chemical treatment program.
In the sulfite pulping process, sodium sulfite (often combined with sodium sulfide or caustic) helps break down lignin in wood chips, while preserving cellulose fibers. Unlike sodium sulfate, which is an inert boiling point raiser in kraft recovery, sulfite actively participates in delignification at 130–170°C. For paper mills, purity matters: metals like iron and copper must be below 15 ppm to avoid discoloration. Our 97%+ pure sodium sulfite ensures consistent brightness and fiber strength, helping mills reduce bleaching chemical consumption downstream.
After bleaching cotton or synthetic textiles with hydrogen peroxide, residual oxidizer must be neutralized immediately to prevent fabric tendering. Sodium sulfite is the preferred anti-chlor and peroxide scavenger because it works quickly in cold water and leaves no harmful byproducts. Cosmetic-grade sodium sulfate has no role here; only a reducing sulfite can halt oxidation. Our heptahydrate form is particularly convenient for textile finishing plants due to its rapid dissolution and easy dosing into wash baths.
Sodium sulfite, often used in combination with lime and sodium sulfide, assists in hair removal from hides by breaking down keratin proteins. Its reducing environment also prevents bacterial growth during the liming process. This application demands a consistent coarse granular product to minimize dust while ensuring chemical activity—Hailei’s QCD mills precisely control particle size for this niche market.
As a mild reducing agent, sodium sulfite protects developing agents (like hydroquinone) from aerial oxidation and enhances the activity of developers in black-and-white photography. While this market is smaller, it demands the highest purity and low chloride content. We supply 98% minimum purity material to specialty chemical formulators worldwide.
When evaluating sodium sulfite bulk price, buyers must look beyond the FOB quote. Key cost factors include:
Current indicative pricing for sodium sulfite anhydrous 97% in bulk (20 MT FCL) ranges from $450 to $550 per metric ton, depending on market conditions and freight. For the heptahydrate, subtract roughly 10–15% due to water weight. We encourage buyers to request a tailored quote through our get a quote page, providing annual volume and target specifications for the most competitive price.
Choosing a sodium sulfite manufacturer is about much more than price. As a B2B buyer, you need a partner that guarantees:
Unlike distributors selling off-spec “sodium sulfate” as a cheaper substitute, Hailei manufactures sodium sulfite with strict ion-exchange membrane technology to remove heavy metals, ensuring your process stays safe and efficient.
Sodium sulfite is hygroscopic and must be kept dry to avoid premature oxidation or caking. We palletize and shrink-wrap each bag, and offer 40-bag air-ride truck loading for domestic deliveries. For ocean shipments, we add desiccant bags inside containers to combat humidity during long transit times. Understanding that the “sodium sulfate in shampoo” query often comes from buyers new to industrial chemicals, we provide straightforward storage guidelines: cool, dry warehouse (<30°C), avoid exposure to acids (which release toxic SO2), and monitor sulfite inventory using simple iodometric titration kits.
While sodium sulfate in shampoo is considered safe and mild, sodium sulfite must be handled with appropriate PPE (gloves, dust mask, goggles). It can cause irritation and, when ingested, release sulfur dioxide gas in the stomach. Our Safety Data Sheets align with GHS Rev.9, and we train clients on proper ventilation during batch dissolution. Spill procedures involve sweeping and disposal as non-hazardous waste in many jurisdictions—again, a clear contrast to the benign image of shampoo ingredients.
Knowing “what is sodium sulfate in shampoo” is just the start. Buyers often ask us: “Can I use sodium sulfite instead of sulfate?” The answer is a firm no—they are not interchangeable. Sulfite’s reducing power would wreak havoc in a detergent formulation, potentially generating irritating SO2 fumes in acidic conditions. Conversely, sulfate in a boiler would provide zero oxygen removal. Always confirm CAS numbers: sodium sulfate is 7757-82-6, while sodium sulfite is 7757-83-7. At Hailei, we label every bag clearly with both the common name and CAS to prevent mix-ups at the receiving dock.
We know that the journey from a search like “what is sodium sulfate in shampoo” to a high-volume industrial purchase is dotted with technical evaluations. That’s why we educate our clients, not just sell chemicals. As a leading sodium sulfite manufacturer, we maintain stock in key global hubs, offer sample for evaluation, and support trial runs to demonstrate our product’s performance in your specific application. Our team includes chemical engineers who speak your process language—whether it’s boiler cycles of concentration, kappa number in pulp, or textile bath ORP values.

When procurement managers and chemical engineers search “what is sodium sulfate in shampoo,” they often encounter a mix of consumer-focused information about hair care ingredients. Yet, for industrial buyers, this query opens a door to a critical distinction: sodium sulfate (Na2SO4), the shampoo thickener, and sodium sulfite (Na2SO3), an essential oxygen scavenger and reducing agent, are two entirely different compounds—each with unique chemistry, applications, and supply chains. At Weifang Hailei Fine Chemical Co., Ltd., we specialize in high-purity sodium sulfite for demanding industrial processes, not the cosmetic grade sulfate found in personal care. Understanding the difference can prevent costly purchasing errors and ensure you source the right chemical for your boiler water treatment, pulp processing, or textile bleaching line.
The question itself reflects a common confusion. Sodium sulfate (Na2SO4), often sold as Glauber’s salt or sulfate of soda, is widely used in shampoo formulations. Its primary role is as a thickener and viscosity modifier: it reduces the electrostatic repulsion between surfactant micelles, allowing shampoos to achieve that rich, gel-like consistency consumers expect. It also acts as a processing aid, making liquid detergents easier to handle. However, sodium sulfate is chemically inert in most personal care contexts—it doesn’t lather, clean, or condition hair. Instead, it’s a functional additive, derived either from natural mineral sources or as a byproduct of chemical manufacturing like rayon production. For industrial buyers, sodium sulfate typically appears in powder or granular form with purity grades of 92–99% depending on the end use, from detergents to glassmaking.
To appreciate the distinction, let’s briefly review sodium sulfate chemical properties. Na2SO4 has a molar mass of 142.04 g/mol, a neutral pH (5–7 in aqueous solution), and high thermal stability (melting point 884°C). It is moderately soluble in water (about 28 g/100 mL at 25°C), and its solubility curve exhibits a maximum near 33°C—important when specifying hydrate forms. Available as anhydrous and decahydrate (Glauber’s salt), it is used in textiles for leveling dyes, in kraft pulp cooking, and as a filler in powdered detergents. None of these applications involve oxygen scavenging or strong reducing power, which is where sodium sulfite enters the picture.
Whenever a buyer mixes up sodium sulfate and sodium sulfite, the consequences can be severe. The sodium sulfite formula compound is Na2SO3, a white crystalline solid that acts as a potent oxygen scavenger and mild reducing agent. In contrast to sulfate’s SO4²⁻ anion, sulfite’s SO3²⁻ anion possesses a lone pair and can readily oxidize to sulfate, making it ideal for removing dissolved oxygen from boiler feedwater, preventing corrosion in power plants. At Hailei, we manufacture both anhydrous sodium sulfite (96–98% purity) and the heptahydrate form (Na2SO3·7H2O), each tailored to specific process temperatures and dosing systems. The anhydrous material is favored for high-temperature boiler treatments due to its stability, while the heptahydrate is easier to handle in ambient conditions and dissolves rapidly.
Sodium sulfite’s chemical properties are distinctly different: it has a molar mass of 126.04 g/mol, a melting point of 33.4°C for the heptahydrate (which decomposes upon further heating), and a pH of 9–10 in solution, indicating an alkaline reaction. This alkalinity is beneficial in boiler water treatment to maintain passivation layers on steel surfaces. The reducing power is quantified by its sulfite content (as SO3²⁻) and the rate of oxygen uptake—critical performance metrics for our industrial clients.
Imagine ordering “sodium sulfate” for your power plant’s deaerator line. At best, the inert salt would do nothing, leaving dissolved oxygen to corrode boiler tubes and cause costly shutdowns. At worst, a casual supplier might send a low-grade sulfate mislabeled as sulfite, leading to catastrophic system failures. We see this confusion often in international procurement, especially where English is not the first language. The similarity in names masks a fundamental difference in function: sodium sulfate is a filler, sodium sulfite is a scavenger. By clarifying “what is sodium sulfate in shampoo” and why it’s irrelevant to your plant, you protect operations and budgets.
In high-pressure boilers, dissolved oxygen must be kept below 7 ppb to avoid pitting corrosion. Catalyzed sodium sulfite reacts rapidly with oxygen to form sodium sulfate (the same product that ends up in shampoo, ironically), but in this context, it’s a controlled reaction that safeguards millions of dollars in infrastructure. Hailei’s sodium sulfite is designed for low-impurity, high-reactivity performance, capable of achieving residual sulfite levels of 20–40 ppm in boiler water—meeting standards like ASME Consensus on Water Chemistry. We provide customized granular sizes to suit volumetric or slurry feed systems, ensuring our sodium sulfite integrates seamlessly into your plant’s chemical treatment program.
In the sulfite pulping process, sodium sulfite (often combined with sodium sulfide or caustic) helps break down lignin in wood chips, while preserving cellulose fibers. Unlike sodium sulfate, which is an inert boiling point raiser in kraft recovery, sulfite actively participates in delignification at 130–170°C. For paper mills, purity matters: metals like iron and copper must be below 15 ppm to avoid discoloration. Our 97%+ pure sodium sulfite ensures consistent brightness and fiber strength, helping mills reduce bleaching chemical consumption downstream.
After bleaching cotton or synthetic textiles with hydrogen peroxide, residual oxidizer must be neutralized immediately to prevent fabric tendering. Sodium sulfite is the preferred anti-chlor and peroxide scavenger because it works quickly in cold water and leaves no harmful byproducts. Cosmetic-grade sodium sulfate has no role here; only a reducing sulfite can halt oxidation. Our heptahydrate form is particularly convenient for textile finishing plants due to its rapid dissolution and easy dosing into wash baths.
Sodium sulfite, often used in combination with lime and sodium sulfide, assists in hair removal from hides by breaking down keratin proteins. Its reducing environment also prevents bacterial growth during the liming process. This application demands a consistent coarse granular product to minimize dust while ensuring chemical activity—Hailei’s QCD mills precisely control particle size for this niche market.
As a mild reducing agent, sodium sulfite protects developing agents (like hydroquinone) from aerial oxidation and enhances the activity of developers in black-and-white photography. While this market is smaller, it demands the highest purity and low chloride content. We supply 98% minimum purity material to specialty chemical formulators worldwide.
When evaluating sodium sulfite bulk price, buyers must look beyond the FOB quote. Key cost factors include:
Current indicative pricing for sodium sulfite anhydrous 97% in bulk (20 MT FCL) ranges from $450 to $550 per metric ton, depending on market conditions and freight. For the heptahydrate, subtract roughly 10–15% due to water weight. We encourage buyers to request a tailored quote through our get a quote page, providing annual volume and target specifications for the most competitive price.
Choosing a sodium sulfite manufacturer is about much more than price. As a B2B buyer, you need a partner that guarantees:
Unlike distributors selling off-spec “sodium sulfate” as a cheaper substitute, Hailei manufactures sodium sulfite with strict ion-exchange membrane technology to remove heavy metals, ensuring your process stays safe and efficient.
Sodium sulfite is hygroscopic and must be kept dry to avoid premature oxidation or caking. We palletize and shrink-wrap each bag, and offer 40-bag air-ride truck loading for domestic deliveries. For ocean shipments, we add desiccant bags inside containers to combat humidity during long transit times. Understanding that the “sodium sulfate in shampoo” query often comes from buyers new to industrial chemicals, we provide straightforward storage guidelines: cool, dry warehouse (<30°C), avoid exposure to acids (which release toxic SO2), and monitor sulfite inventory using simple iodometric titration kits.
While sodium sulfate in shampoo is considered safe and mild, sodium sulfite must be handled with appropriate PPE (gloves, dust mask, goggles). It can cause irritation and, when ingested, release sulfur dioxide gas in the stomach. Our Safety Data Sheets align with GHS Rev.9, and we train clients on proper ventilation during batch dissolution. Spill procedures involve sweeping and disposal as non-hazardous waste in many jurisdictions—again, a clear contrast to the benign image of shampoo ingredients.
Knowing “what is sodium sulfate in shampoo” is just the start. Buyers often ask us: “Can I use sodium sulfite instead of sulfate?” The answer is a firm no—they are not interchangeable. Sulfite’s reducing power would wreak havoc in a detergent formulation, potentially generating irritating SO2 fumes in acidic conditions. Conversely, sulfate in a boiler would provide zero oxygen removal. Always confirm CAS numbers: sodium sulfate is 7757-82-6, while sodium sulfite is 7757-83-7. At Hailei, we label every bag clearly with both the common name and CAS to prevent mix-ups at the receiving dock.
