Sodium Cyclamate

Sodium Cyclamate is a non-nutritive sweetener belonging to the cyclic sulfamate family. It is the sodium salt of cyclohexanesulfamic acid and delivers a sweetness intensity of roughly 30 to 50 times that of sucrose, the lowest potency among the widely used intense sweeteners.

The compound has the formula C₆H₁₂NNaO₃S and a molar mass of 201.22 g/mol. It is a white, odourless crystalline powder, freely soluble in water and slightly soluble in ethanol.

The sweetness profile is slow-onset with a clean, sucrose-like taste and a lingering finish. Because the potency is modest by intense-sweetener standards, sodium cyclamate is almost always used in synergistic blends with saccharin (typically 10 parts cyclamate to 1 part saccharin), where it masks the metallic edge of saccharin and rounds out the overall sweetness.

We source bulk Sodium Cyclamate from top China manufacturers for our partners, working with several of them. The manufacturers are mostly in Jiangsu, Hebei and Tianjin. For this ingredient the minimum order is 1,000 kg and a 20-foot container takes 20 MT, and 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

There are two grades of sodium cyclamate: food and pharmaceutical. Both assay at 98 percent minimum on the dried basis, the pharmaceutical grade to the tighter pharmacopoeial specification.

The standard physical form is a crystalline powder. Several particle-size distributions are produced for different end uses. A coarser grade is preferred for tabletop tablets and direct addition to syrups, while a finer milled grade is used in dry beverage mixes and pharmaceutical tablet manufacture.

Pharmaceutical-grade material complies with the European Pharmacopoeia (Ph. Eur.) and the British Pharmacopoeia (BP) monographs. The specification includes tight limits on residual cyclohexylamine, the principal impurity of regulatory concern.

Applications

Tabletop sweeteners in tablet, liquid, and granular formats, commonly blended with sodium saccharin
Diet carbonated soft drinks, flavoured waters, and powdered drink mixes (in markets where approved)
Sugar-free fruit nectars, juices, and reduced-calorie beverages
Low-calorie dairy products: yogurt drinks, flavoured milks, and chocolate milk
Sugar-free jams, jellies, fruit preserves, and marmalades
Canned fruits in light syrup and reduced-sugar fruit cocktails

How We Help Source Sodium Cyclamate

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 Cyclamate 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 Cyclamate 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 cyclamate has one of the most complex regulatory histories of any food additive.

The United States Food and Drug Administration approved cyclamate in 1958 and added it to the GRAS list. Following a 1969 study reporting bladder tumors in rats fed a 10:1 cyclamate-saccharin mixture, the FDA banned cyclamate for use in food on October 18, 1969. The ban remains in force today, although Abbott Laboratories and the Calorie Control Council have repeatedly petitioned for reinstatement based on subsequent toxicology data, with petitions filed in 1973 and again in 1982. The FDA has not formally denied the most recent petition but has not approved reinstatement either.

In the European Union Regulation (EC) No 1333/2008 approves sodium cyclamate under E number E952 and defines the use levels per food category. Health Canada permits cyclamate as a tabletop sweetener and in pharmaceutical preparations. China permits cyclamate as a sweetener. More than 50 other countries permit its use in foods and beverages.

Pharmacopoeial monographs for sodium cyclamate appear in the European Pharmacopoeia (Ph. Eur.) and the British Pharmacopoeia (BP). Halal and Kosher certifications are commonly available because the manufacturing process uses no animal-derived inputs.

Manufacturing Process

Sodium Cyclamate Manufacturing Process

Loading process diagram…

The industrial synthesis of sodium cyclamate is straightforward and has changed little since the 1950s.

Cyclohexylamine is sulfonated with sulphur trioxide, chlorosulfonic acid, or sulfamic acid in a suitable solvent system. The reaction yields cyclohexanesulfamic acid, the free acid form of the sweetener.

The crude acid is neutralised with sodium hydroxide or sodium carbonate to form the sodium salt. The salt is recovered by crystallisation from water or aqueous ethanol, treated with activated carbon for decolorisation, and recrystallised to specification purity.

The dried crystals are milled to the target particle size and screened. Process control focuses on minimising residual cyclohexylamine, which is the principal regulated impurity and a degradation product of cyclamate metabolism in some individuals.
