Chemical Name: Sodium Cyclamate
Common Name: Artificial sweetener, additive E952
Physical Appearance: White, odorless crystalline powder
Major Uses: Food and beverage sweetening, some pharmaceuticals, tabletop sugar substitutes
CAS Number: 139-05-9
Main Risks: Inhalation of dust causes throat irritation, coughing, and sneezing. Large accidental ingestion leads to stomach upset or nausea for sensitive individuals. Prolonged high-dose exposure brings up debate around bladder tumors in animal studies, sparking regulatory bans and restrictions in some countries.
Warning Symbols: Many jurisdictions mark it as not classified as hazardous under GHS, but limited toxicological data mean safe handling matters.
Substance: Sodium Cyclamate, single ingredient
Chemical Formula: C6H12NNaO3S
Purity: Commercial-grade usually exceeds 98%
Impurities: Low levels of related cyclamate compounds or sulfamic acid possible, but reputable supply keeps these under regulated limits.
Inhalation: Move to fresh air, rinse mouth, and keep at rest for relief. Seek medical advice with continued irritation.
Eye Contact: Rinse carefully with plenty of clean water for several minutes. Remove contact lenses if present. Persistent redness needs a doctor’s visit.
Skin Contact: Wash off with soap and water.
Ingestion: Rinse mouth, drink some water. Large amounts call for medical attention, but minor accidental tastes are handled by the body.
Suitable Extinguishing Media: Water spray, dry chemical powder, carbon dioxide can tackle fires involving this powder.
Special Hazards: Burns clean, but decomposes at high heat with risk of releasing sulfur oxides and nitrogen oxides.
Protective Equipment: Firefighters use self-contained breathing apparatus to dodge fume inhalation.
Spill Response: Sweep up powder carefully, avoid dust clouds, and shovel into a suitable dry container.
Protective Steps: Gloves and a dust mask help avoid irritation or inhaling powders.
Environmental Issues: Sweep up right away to avoid unnecessary contact with wildlife or water runoff.
Handling Precautions: Work gets safer with dust control measures and good airflow.
Safe Storage: Keep the container tightly sealed, stored in a cool, dry place away from strong acids and oxidizing agents.
Cross-contamination: Food facilities focus on thoroughly cleaning equipment after cyclamate production.
Ventilation: Use local exhaust or adequate ventilation when powder handling gets heavy.
Protective Gear: Wearing goggles, dust masks, and gloves in bulk operations prevents accidental exposure.
Exposure Limits: Legal limits vary, but routine use in the US is not allowed for food, restricting most work uses to specialty industrial settings.
Appearance: White crystalline or granular powder
Odor: Odorless, does not taint products it sweetens
Solubility: Freely soluble in water
Melting Point: Decomposes above 260°C
Stability: Stable at room temperature in sealed containers out of sunlight
Chemical Stability: The compound stays stable under normal storage conditions.
Reactivity: Reacts with strong acids to release cyclamic acid, which is less stable. Combustion or high heat releases irritating gases.
Avoid: Strong oxidizing agents and strong acids keep it out of trouble.
Acute Toxicity: Low for humans in typical use. Animal studies at high doses link to bladder cancer, fueling bans in the US and bans or limits elsewhere.
Chronic Exposure: Long-term heavy exposure should be avoided, especially in workplaces handling tonnage.
Allergic Effects: Rare, but skin contact brings mild irritation for some.
Aquatic Life: Low toxicity, but release into waterways in large amounts is unwise and should always be avoided.
Persistence: Not known to readily degrade in the environment.
Bioaccumulation: Not expected to accumulate in living organisms based on available studies.
Waste Disposal: Dispose of in line with local and national guidelines for chemical waste. Mixing cyclamate in bulk with landfills or natural waterways causes unnecessary risk.
Packaging: Ensure empty bags, drums, or bottles are well-rinsed before landfill or recycling.
Incineration: Where allowed, clean destruction in a facility designed for chemical disposal prevents breakdown products from entering the regular waste stream.
UN Classification: Not classified as dangerous for transport under normal regulations, but carriers must prevent leaks with robust packaging.
Labeling: Mark as an artificial sweetener, prevent punctures or moisture exposure in transit.
Stability During Shipping: Powder stays stable if kept dry and cool; humidity clumping is a bigger nuisance than hazard.
Food Additive Status: Banned as a sweetener in the US since 1969, but allowed in the European Union, China, and other regions with strict maximum amounts.
Occupational Rules: Handlers follow local chemical safety guidelines and industry standards for artificial sweeteners.
Consumer Products: Regulations vary wildly—always check the label claims against the law if handling products with imported cyclamates.
Worker Rights: Employees deserve access to up-to-date safety training and personal protection in any facility using or processing sodium cyclamate.
