If you are a procurement manager sourcing sodium sulphate for manufacturing, you have probably come across the query “what is sodium sulphate in food” during supplier research. Sodium sulphate (Na2SO4) in food refers to the food-grade variant designated as E514 by the European Union. It acts as a diluent for food colours, an acidity regulator, and a carrier for synthetic flavourings. While chemically identical to industrial-grade anhydrous sodium sulphate, food-grade material must comply with stringent purity and safety regulations, making it a completely different product from the industrial grades typically used in detergents, glass, and pulp production.
For industrial buyers, understanding this distinction is critical. Using the wrong grade can lead to product rejection, regulatory violations, and costly production issues. In this comprehensive guide, Hailei Fine Chemical clarifies what sodium sulphate in food actually is, contrasts it with industrial grades, and explains where high-purity anhydrous sodium sulphate fits into large-scale manufacturing.
When people ask “what is sodium sulphate in food”, they are usually referring to the additive E514(i) (sodium sulphate) or E514(ii) (sodium hydrogen sulphate). E514 is permitted in a narrow range of processed foods, often at very low concentrations. Typical applications include:
Food-grade sodium sulphate must meet standards such as the FCC (Food Chemicals Codex) or EU Regulation (EC) No 231/2012. Typical specifications for food-grade Na2SO4 include a minimum assay of 99.0 %, but far more importantly, they enforce very low limits on heavy metals: arsenic ≤ 3 mg/kg, lead ≤ 2 mg/kg, and mercury ≤ 1 mg/kg. Chlorides, iron, and selenium are also tightly controlled. These stringent purity requirements separate food-grade material from standard industrial anhydrous sodium sulphate, which may contain trace levels of these elements well above food-safe limits.
For industrial buyers, the most actionable question is not “what is sodium sulphate in food” but “how different is it from what I need?” The table below summarises the key contrasts.
| Parameter | Food-Grade (E514) | Industrial-Grade (Hailei 99 % min) |
|---|---|---|
| Typical Purity (Na2SO4) | ≥ 99.0 % on dried basis | ≥ 99.0 % (anhydrous) |
| Heavy Metals (as Pb) | ≤ 5 mg/kg | Not guaranteed; typically ≤ 10–20 mg/kg |
| Arsenic | ≤ 3 mg/kg | Not controlled to food level |
| Iron (Fe) | ≤ 10 mg/kg | ≤ 50 mg/kg (may vary) |
| Moisture | ≤ 1.0 % | ≤ 0.3 % (low moisture for storage) |
| Whiteness | Not specified | > 82 % (critical for detergents) |
| Certification | FCC, EC 231/2012, Halal, Kosher | GB/T 6009-2014, ISO 9001, REACH |
| Packaging | 25 kg food-grade paper bags with PE liner | 25/50 kg PP woven bags, 1000 kg jumbo bags |
Notice that even though both grades can share the same Na2SO4 assay, the real gap lies in the trace element profile and certification. Do not be misled by a 99 % purity claim alone—always ask for a certificate of analysis (COA) with heavy metal test results if your application has indirect food contact or regulatory exposure.
Another frequent confusion arises between sodium sulphate (Na2SO4) and sodium sulphite (Na2SO3). The search query “sodium sulphate and sodium sulphite” often comes from procurement professionals who need to identify the correct chemical for their process. Though the names sound similar, the compounds differ in oxidation state and reactivity:
If your mill is running a kraft pulping process, you may encounter sodium sulphate as a makeup chemical in the recovery boiler, where it is reduced to sodium sulphide.
Using sodium sulphite by mistake will not provide the same chemical balance and can create dangerous SO2 off-gassing. Always verify the CAS number: 7757-82-6 for sodium sulphate vs. 7757-83-7 for sodium sulphite. When ordering bulk chemicals from overseas suppliers, include both the chemical name and CAS number in your purchase order to avoid costly errors.
Searches like “best sodium lauryl sulphate free toothpaste” and “sds sodium dodecyl sulphate” often intersect with sodium sulphate queries because of the abbreviation “SLS” and the word “sulphate”. It is essential to separate these chemicals for your team.
The confusion stems from the word “sulphate” in both names and the fact that industrial sodium sulphate is used in detergent powders—but there it functions as an inert filler, not as the active surfactant. Your detergent formulation likely requires both sodium sulphate (filler, flow aid) and a surfactant such as linear alkylbenzene sulphonate (LABS) or sodium lauryl sulphate. Knowing the difference prevents mis-specification during raw material sourcing.
While researching “what is sodium sulphate in food”, some readers also stumble upon “sodium hydrogen sulfate uses”. Sodium hydrogen sulfate (NaHSO4), also called sodium bisulfate, is the acidic half-neutralised form of sulphuric acid. It should not be confused with the neutral sodium sulphate (Na2SO4). Key applications of sodium hydrogen sulfate include:
Sodium hydrogen sulfate is hygroscopic and releases sulphuric acid when dissolved in water, making it corrosive. In contrast, sodium sulphate solutions are neutral (pH 6–8) and non-corrosive under normal conditions. For manufacturers looking to handle dry, free-flowing, neutral salts in large volumes, anhydrous sodium sulphate is far simpler to store and convey than the acidic sodium bisulfate.
Moving beyond food-grade questions, most Hailei customers require industrial-grade sodium sulphate for high-volume manufacturing. Our product, available at industrial-grade anhydrous sodium sulphate, is a white, free-flowing powder or granular material with the following typical specifications:
These properties make it suitable for the following sectors:
Anhydrous sodium sulphate is the most common filler in laundry powders, comprising 20–60 % of the formulation. It provides bulk, improves powder flow, and aids dissolution without affecting detergency. The high whiteness and low iron content of Hailei’s sodium sulphate ensure no discolouration in light-coloured detergent granules. Our product is shipped in 1000 kg jumbo bags for efficient pneumatic conveying into spray drying towers. Bulk sodium sulphate for detergent manufacturing is available year-round with stable quality.
In container glass and flat glass production, sodium sulphate serves as a fining agent and flux. It helps remove bubbles from the melt and lowers the melting temperature of silica. Typically, 0.5–2 % by batch weight is added. The low moisture content of our anhydrous material reduces energy consumption during charging and avoids steam bursts in the furnace.
Textile mills use sodium sulphate to promote level dyeing with direct and reactive dyes. The neutral salt helps drive the dye from the solution onto the fibre, improving colour yield. A consistent particle size and high purity ensure uniform dissolution in dye baths, preventing spotting on finished fabric. We supply textile-grade sodium sulphate with strict limits on water-insoluble matter.
In the kraft process, sodium sulphate is added as make-up chemical to the black liquor recovery boiler, where it is reduced to sodium sulphide. This maintains the sulphidity of the cooking liquor. Pulp mills typically require Na2SO4 in large quantities—shipments of 20–27 metric tonnes per container are standard. Hailei Fine Chemical offers consistent sizing and minimal inert impurities to support high-efficiency chemical recovery.
Anhydrous sodium sulphate is used as a raw material for producing sodium sulphide, sodium silicate, and other sulphur-containing chemicals. Its stable composition and low chloride level make it a reliable intermediate for downstream synthesis.
Bulk chemical procurement involves more than just comparing price per metric tonne. To ensure you get the appropriate grade—whether food, pharmaceutical, or industrial—follow this checklist:
Returning to the original question—”what is sodium sulphate in food”—the real lesson for industrial buyers is that not all sodium sulphate is created equal. Using food-grade E514 in detergent powder would be economically unjustified, adding 30–50 % to raw material costs without any performance gain. Conversely, mistakenly using industrial-grade sodium sulphate in a process that eventually touches food could trigger failed audits, product recalls, and severe regulatory penalties.

Many procurement professionals and chemical engineers researching what is sodium sulphate in food are surprised to learn that the same compound powers multiple industries outside of the food sector. This query often arises because industrial buyers encounter confusing product specifications, cross-contaminated search results, or mistaken chemical identities when sourcing anhydrous sodium sulphate for large-scale manufacturing. At Weifang Hailei Fine Chemical Co., Ltd., we help you navigate this complexity with clarity. This article demystifies sodium sulphate across food and industrial domains, unpacks common chemical confusions like sodium sulphite and sodium lauryl sulphate, and guides you toward the right high-purity material for detergents, glass, textiles, and pulp production.
When someone asks what is sodium sulphate in food, they are typically referring to the food additive designated as E514. Sodium sulphate (Na₂SO₄) is approved by the Codex Alimentarius and regional food safety authorities as a processing aid and minor additive. In food-grade form, it serves as a diluent for powdered drink mixes, a firming agent in confectionery, an acidity regulator in certain processed foods, and as a carrier for flavorings. However, its applications are extremely limited compared to its industrial use. Food-grade sodium sulphate must meet strict purity criteria—typically over 99.0% purity with extremely low heavy metal and arsenic contaminants—far exceeding the specifications required for most technical grades.
It is critical to understand that food-grade sodium sulphate is not interchangeable with industrial-grade sodium sulphate. The latter, which we supply to manufacturers worldwide, is optimized for performance in detergents, glass melting, textile dyeing, and kraft pulping, but is not safe for human consumption. If a buyer searches “what is sodium sulphate in food,” they should first clarify their end-use requirement. Are you a food processor needing a certified E514 supplier? Or an industrial buyer inadvertently caught in food-related keyword results? This distinction can save costly procurement errors.
While food-grade sodium sulphate has a niche role, industrial-grade anhydrous sodium sulphate (purity ≥99%) is a true workhorse in global B2B supply chains. At Hailei Chemical, our anhydrous sodium sulphate is a versatile, cost-effective filler and processing aid. Its primary applications include:
Our product is available in multiple packaging options—25 kg PP woven bags, 50 kg bags, or 1000 kg big bags—and can be supplied to your precise granulation or anti-caking requirements. For industrial buyers searching information on what is sodium sulphate in food, this is the inflection point: recognize that the same chemical identity serves entirely different purposes depending on purity grade and intended use.
A frequent source of confusion in chemical purchase specifications is the mix-up between sodium sulphate (Na₂SO₄) and sodium sulphite (Na₂SO₃). Although their names sound strikingly similar—often confounded in procurement requisitions—these two compounds possess distinct chemical behaviors and application profiles.
Sodium sulphite is a reducing agent widely used as an oxygen scavenger in boiler water treatment, a preservative in food (E221), and a dechlorinating agent in water treatment. It is also a key component in photographic developers and textile bleaching. In contrast, sodium sulphate is an inert, neutral salt that acts predominantly as a filler, diluent, or processing aid, not as a reactive chemical.
For sourcing decisions, note the following:
When requesting a quotation or SDS, always reference the precise CAS number and desired purity to avoid costly mix-ups. If your application involves bleaching, preservation, or oxygen removal, you likely need a sulphite, not a sulphate. Our team at Hailei Chemical can guide you if you’re uncertain—we offer a wide range of industrial chemicals to match the right product to your process.
The search landscape reveals abundant queries where sodium sulphate is mistaken for other sodium compounds with similar-sounding names. As a B2B buyer, you might encounter terms like “best sodium lauryl sulphate free toothpaste,” “SDS sodium dodecyl sulphate,” or “sodium hydrogen sulfate uses” while researching industrial inputs. Let’s clarify these once and for all.
Consumer searches for best sodium lauryl sulphate free toothpaste refer to sodium lauryl sulphate (SLS), a synthetic surfactant that creates foam in toothpaste and shampoos. SLS (C₁₂H₂₅SO₄Na) is chemically an organosulfate, not an inorganic salt like our sodium sulphate. The “sulfate” in SLS denotes a sulfate ester of lauryl alcohol, whereas sodium sulphate is simply Na₂SO₄. Buyers seeking SLS for detergent formulations should not confuse these two—SLS is a much higher-cost specialty surfactant, while sodium sulphate is a bulk filler. If you’re in the personal care supply chain, remember that SLS is not a substitute for sodium sulphate, nor vice versa. Our industrial sodium sulphate finds no use in toothpaste; its role remains firmly in laundry powders, glass melts, and paper mills.
The acronym SDS sodium dodecyl sulphate often appears in biotech and laboratory contexts. Here, SDS (also known as sodium lauryl sulphate) is used in gel electrophoresis and protein denaturation. This high-purity reagent-grade chemical should never be confused with the Safety Data Sheet (SDS) for sodium sulphate—a document every industrial chemical supplier provides for regulatory compliance. When dealing with our range of industrial chemicals, you’ll always receive a comprehensive SDS that details safe handling, storage, and transport. It’s a critical document, but it’s not the same thing as the chemical SDS.
Sodium hydrogen sulfate (NaHSO₄), also called sodium bisulfate, is an acidic salt used primarily as a pH reducer for swimming pools, in metal finishing, and as a cleaning agent for ceramic tiles. Its uses are far from the neutral filler role of sodium sulphate. Key differences:
Procurement teams ordering “sulfate” compounds should always cross-check the full chemical name and CAS number. A single vague purchase order can result in receiving the wrong chemical, leading to process disruptions and safety hazards.
For B2B buyers in the detergent, glass, textile, and pulp industries, the primary concern isn’t what is sodium sulphate in food—it’s the availability of consistent, high-purity anhydrous material at a competitive price. That’s where Weifang Hailei Fine Chemical Co., Ltd. excels. With years of export experience, we deliver sodium sulphate that meets the most stringent industrial specifications:
We understand that logistics and documentation are paramount in overseas trade. Every shipment includes a certificate of analysis, country-of-origin certification, and, if required, pre-shipment inspection by a recognized third party. Our logistic partners ensure cost-effective sea freight from Qingdao or Shanghai.
To crystallize the differences that often perplex buyers searching “what is sodium sulphate in food,” here is a practical comparison table for quick reference:
| Parameter | Food Grade (E514) | Industrial Grade (Typical) |
|---|---|---|
| Purity (min) | 99.0–99.5% | ≥99.0% (often 99% for our product) |
| Heavy metals (as Pb) | ≤2 mg/kg | ≤10 mg/kg (varies) |
| Arsenic (As) | ≤1 mg/kg | ≤2 mg/kg |
| Intended use | Limited food processing aids | Detergent filler, glass, pulp, textiles |
| Regulatory standard | FCC, JECFA, EU 231/2012 | GB/T 6009 (China), industrial specs |
| Typical packaging | Small bags, paper sacks | 25 kg/50 kg/1000 kg bulk bags |
Industrial buyers must never accept food-grade material for their processes unless specifically required; the price premium and unnecessary purity specs inflate costs without any performance benefit. Conversely, industrial-grade must never enter the food chain. Clear documentation from your supplier is essential.
Sodium sulphate (Na₂SO₄) is a neutral filler and processing salt, while sodium sulphite (Na₂SO₃) is a reducing agent used for oxygen scavenging, preservation, and bleaching. They have different CAS numbers, chemical behaviors, and application scopes. Always check the label and SDS.
No. Cosmetic formulations containing “sulfate” typically use sodium lauryl sulphate (SLS) or sodium laureth sulphate (SLES) as foaming agents. Sodium sulphate is not a surfactant and is not used in toothpaste or shampoos. If you are searching for SLS-free toothpaste, you are dealing with an entirely different chemical space.
A Safety Data Sheet (SDS) for sodium sulphate provides information on hazard identification (it is generally non-hazardous), first-aid measures, firefighting measures, handling and storage, exposure controls, and physical/chemical properties. Our SDS includes all 16 sections compliant with GHS. Do not confuse the document “SDS” with the chemical SDS (sodium dodecyl sulphate).
Sodium hydrogen sulfate (sodium bisulfate) is used to lower pH in swimming pools, as a cleaning agent, and in metal finishing. It is acidic and significantly different from sodium sulphate. Industrial buyers should ensure they order the correct “sulfate” salt for their process.
The question what is sodium sulphate in food opens a window into the broader landscape of this versatile inorganic salt—a landscape where the same chemical identity serves divergent roles based on grade and application.

Industrial buyers must never accept food-grade material for their processes unless specifically required; the price premium and unnecessary purity specs inflate costs without any performance benefit. Conversely, industrial-grade must never enter the food chain. Clear documentation from your supplier is essential.
Sodium sulphate (Na₂SO₄) is a neutral filler and processing salt, while sodium sulphite (Na₂SO₃) is a reducing agent used for oxygen scavenging, preservation, and bleaching. They have different CAS numbers, chemical behaviors, and application scopes. Always check the label and SDS.
No. Cosmetic formulations containing “sulfate” typically use sodium lauryl sulphate (SLS) or sodium laureth sulphate (SLES) as foaming agents. Sodium sulphate is not a surfactant and is not used in toothpaste or shampoos. If you are searching for SLS-free toothpaste, you are dealing with an entirely different chemical space.
A Safety Data Sheet (SDS) for sodium sulphate provides information on hazard identification (it is generally non-hazardous), first-aid measures, firefighting measures, handling and storage, exposure controls, and physical/chemical properties. Our SDS includes all 16 sections compliant with GHS. Do not confuse the document “SDS” with the chemical SDS (sodium dodecyl sulphate).
Sodium hydrogen sulfate (sodium bisulfate) is used to lower pH in swimming pools, as a cleaning agent, and in metal finishing. It is acidic and significantly different from sodium sulphate. Industrial buyers should ensure they order the correct “sulfate” salt for their process.
