Supplier Details: Manufacturer or distributor’s address, phone, emergency contact information
Emergency Phone: Reference to local poison centers or CHEMTREC for immediate assistance
Hazard Classification: Not classified as hazardous according to GHS
Main Hazards: Minor irritation possible in eyes, nose, and throat with excessive dust
Signal Word: Not required
GHS Pictograms: No pictogram assigned
Precautionary Statements: Avoid creating or breathing dust; use adequate ventilation
Other Hazards: No significant flammability, reactivity, or acute toxicity with normal handling
Chemical Identity: Acesulfame Potassium
CAS Number: 55589-62-3
Purity: More than 99% by weight
Impurities: Minimal, may contain trace elements from manufacture not exceeding permitted limits for food grade status
Ingredients: Ingredient is the active sweetening compound itself, with no hazardous contaminants noted
Inhalation: Move person to fresh air if dust inhaled; seek medical attention for allergies or persistent symptoms
Skin Contact: Wash thoroughly with soap and water; seek medical help if irritation persists
Eye Contact: Rinse immediately with plenty of water for several minutes; remove contact lenses; get further help if irritation continues
Ingestion: Rinse mouth out, drink water to dilute in stomach, consult doctor for large or symptomatic exposure
Medical Notes: Supportive care based on symptoms is generally sufficient, as the compound exhibits low acute toxicity in most cases
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide
Specific Hazards: May emit sulfur oxides, nitrogen oxides, or potassium compounds during combustion
Protective Equipment: Firefighters should wear respiratory protection and full gear due to smoke and fume hazards
Other Advice: Avoid breathing combustion products; use standard firefighting methods for organic powder fires
Personal Precautions: Keep unprotected individuals away, control dust formation, provide adequate ventilation
Environmental Precautions: Prevent runoff into drains, sewers, or surface water
Cleanup Methods: Collect spilled powder by sweeping or vacuuming into suitable containers; wash area with water to remove residues
Disposal: Handle as non-hazardous solid waste, following local requirements
Protective Gear: Use gloves, dust mask, and goggles if risk of inhalation or eye contact exists during cleanup
Handling: Minimize dust production, handle in well-ventilated spaces, avoid inhaling powders
Storage Conditions: Store in dry, cool locations, tightly closed in original packaging or suitable sealable container
Storage Incompatibilities: Keep away from strong oxidizers, acids
Other Precautions: Store away from humidity and moisture, label containers clearly
Engineering Controls: Local exhaust or adequate ventilation to control airborne dust
Respiratory Protection: Dust mask or particulate respirator for high dust environments
Skin Protection: Gloves if long or repeated exposure foreseen
Eye Protection: Use safety goggles when handling powders
Hygiene Measures: Wash hands and face after handling; keep food and drink away from work area
Exposure Limits: Not established for acesulfame potassium; follow general dust exposure guidelines (ACGIH TLV for dusts: 10 mg/m³ total dust, 3 mg/m³ respirable dust)
Physical State: Crystalline powder
Color: White
Odor: Odorless or faintly sweet
Molecular Weight: 201.24 g/mol
Melting Point: Decomposes at 225°C
Solubility: Freely soluble in water; slightly soluble in ethanol
pH (1% Solution): Approximately neutral (6-7)
Boiling Point: Not applicable (decomposes before boiling)
Vapor Pressure: Negligible
Flash Point: Not applicable
Density: Near 1.81 g/cm³
Partition Coefficient (log Kow): -2.0 (very water soluble)
Chemical Stability: Stable under normal temperatures and atmospheric conditions
Conditions to Avoid: High heat, open flames, direct sunlight, excessive moisture
Incompatible Materials: Strong oxidizing agents, acids
Hazardous Decomposition: Sulfur oxides, nitrogen oxides, potassium oxide can evolve at high temperatures
Polymerization: No hazardous polymerization expected
Acute Toxicity: Oral LD50 estimated around 6,900 mg/kg in rats
Skin/Eye Contact: No significant irritation on intact skin or eyes at normal exposure
Carcinogenicity: Not classified by IARC, NTP, or OSHA
Mutagenicity: Negative in most in vitro and animal studies
Chronic Toxicity: No known human health effects at expected intake levels; long history of use in food products without proven adverse effects
Sensitization: Rare; cases of allergic response not widely reported
Other Toxic Effects: No evidence of reproductive or developmental harm at low doses
Ecotoxicity: Low acute toxicity to aquatic organisms; studies in Daphnia and fish report EC50 values much higher than likely environmental concentrations
Persistence and Degradability: Compound stable in the environment; may persist in wastewater and surface waters
Bioaccumulation: Not expected to bioaccumulate due to high water solubility and rapid excretion
Mobility: High mobility through water systems likely, limited soil binding
Other Environmental Effects: Limited decomposition under typical environmental conditions; routine analytical detection in treated municipal wastewater reported in some studies
Waste Disposal: Handle in accordance with local, regional, and national regulations; treat as non-hazardous chemical waste
Methods: Incineration or landfilling in approved facilities; avoid flushing large amounts to sewer systems
Packaging Disposal: Recycle packaging where possible; otherwise, dispose in approved landfill or incinerator
Special Precautions: Prevent uncontrolled environmental release during bulk disposal
Additional Notes: Most users can discard small consumer quantities to general household waste, but large quantities require formal chemical disposal
UN Number: No classification or UN number required
Proper Shipping Name: Not regulated for transport
Transport Hazard Class: Not classified
Packing Group: Not applicable
Environmental Hazards: Not a marine pollutant
Special Transport Notes: Ship in sealed containers, protected from moisture and sources of contamination; follow basic chemical hygiene protocols during loading and unloading, especially for bulk amounts
US: FDA approves for use as sweetener; not considered hazardous under OSHA Hazard Communication Standard
EU: Permitted as food additive (E950); not listed for special handling under REACH
