Sodium Saccharin Anhydrous
Sodium Saccharin Anhydrous is the water-free crystalline form of the sodium salt of saccharin. It is chemically identical to the dihydrate variant in its sweetening action, delivering 300 to 500 times the sweetness of sucrose, but it carries no water of crystallisation in the solid state.
The compound has the formula C₇H₄NNaO₃S and a molar mass of 205.16 g/mol, compared with 241.19 g/mol for the dihydrate. The roughly 15 percent reduction in molecular weight means that an anhydrous-basis dose delivers proportionally more sweetness equivalent per gram weighed out.
The anhydrous form is the preferred saccharin grade for dry-blend applications where moisture is undesirable. Dry beverage powders, instant tablet bases, effervescent formulations, and anhydrous tabletop sweetener sachets all benefit from the lower hygroscopic load and the higher dosing density per unit mass.
We source bulk Sodium Saccharin Anhydrous from top China manufacturers for our partners. The manufacturer is in Hebei. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
A single food and pharmaceutical grade covers sodium saccharin anhydrous, at 99 percent minimum assay on the dried basis.
The standard form is a fine to medium crystalline powder with low residual moisture, typically below 1 percent loss on drying. A micronized grade with mean particle size below 30 micrometers is produced for direct compression tabletting and high-speed dry-mix lines.
A granular grade with mean particle size of 100 to 300 micrometers improves flow on automated sachet-filling equipment and reduces dust during dry blending. The anhydrous form is the standard saccharin variant for any application where free water in the formulation would compromise shelf life or initiate caking of co-blended ingredients.
Pharmaceutical-grade anhydrous material complies with USP, Ph. Eur., BP, and JP monographs. The pharmacopoeial specifications add limits on toluenesulfonamides and other process-related impurities, and explicitly distinguish the anhydrous form for excipient use in dry dosage forms.
Applications
- Dry-blend tabletop sweeteners in sachet and tablet format
- Direct compression tablet formulations including chewable vitamins and effervescent supplements
- Instant powdered drink mixes where free moisture would shorten shelf life
- Dry beverage premixes for soft drinks, iced tea, and lemonade powders
- Powdered dessert and pudding mixes
- Dry gum bases and powdered confectionery centres
- Pharmaceutical tablet excipient blends for taste masking of bitter actives
- Effervescent vitamin, mineral, and analgesic tablets where moisture initiates premature reaction
- Anhydrous flavour concentrates and dry seasoning blends
- Dry premixes for animal feed and pet treats
- Toothpaste tablet and powdered dentifrice formulations
- Spray-dried sweetener systems where the anhydrous form simplifies moisture balance

How We Help Source Sodium Saccharin Anhydrous
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Sodium Saccharin Anhydrous out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Sodium Saccharin Anhydrous together with other ingredients such as Stevia, Erythritol and Maltitol into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Sodium saccharin anhydrous shares the regulatory framework of the dihydrate form. Both are the same chemical entity under food and pharmaceutical regulations, differing only in physical state.
In the European Union the substance carries the E number E954 under Regulation (EC) No 1333/2008, with use levels defined per food category in Annex II.
The U.S. Food and Drug Administration permits saccharin and its salts as a non-nutritive sweetener under 21 CFR 180.37. The National Toxicology Program removed saccharin from its Report on Carcinogens in 2000, and the Saccharin Notice Repeal Act of 2001 ended the previous warning-label requirement.
JECFA has evaluated saccharin and its salts and assigned acceptable status. Pharmacopoeial monographs for the anhydrous form appear in the United States Pharmacopeia (USP), the European Pharmacopoeia (Ph. Eur.), the British Pharmacopoeia (BP), and the Japanese Pharmacopoeia (JP). Halal and Kosher certifications are commonly available.
Manufacturing Process
Sodium saccharin anhydrous is produced through the same upstream synthesis as the dihydrate form, then dried under controlled conditions to drive off the water of crystallisation.
The Remsen-Fahlberg or Maumee process yields saccharin acid, which is neutralised with sodium hydroxide to form the sodium salt in aqueous solution. The dihydrate crystallises from this solution under standard cooling.
To obtain the anhydrous form, the dihydrate is dehydrated under vacuum or in a heated air stream at temperatures in the range of 110 to 140 degrees Celsius. The two water molecules are released and removed, leaving the anhydrous crystal structure intact.
The dried product is milled or granulated to the target particle-size distribution and screened. Packaging uses moisture-barrier liners to prevent rehydration during transport and storage, since the anhydrous form will slowly take up ambient moisture and revert toward the dihydrate at high relative humidity.
