Chemical Name: Disodium 6-hydroxy-5-[(2-methoxy-5-methyl-4-sulfonatophenyl)azo]naphthalene-2-sulfonate
Common Names: Allura Red, FD&C Red 40
CAS Number: 25956-17-6
EC Number: 247-368-0
Concentration: Greater than 90% Allura Red, trace amounts of subsidiary coloring agents and sodium salts as typical impurities
Eye Contact: Rinse with plenty of water for several minutes, remove contact lenses if present, continue rinsing, seek medical attention if irritation persists
Skin Contact: Wash area thoroughly with soap and water, remove contaminated clothing, consult doctor if irritation develops
Inhalation: Move to fresh air, monitor for respiratory symptoms, seek medical attention if coughing or breathing difficulty appears
Ingestion: Rinse mouth, drink water, avoid inducing vomiting, consult poison control or physician
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide
Unsuitable Extinguishing Media: Strong direct water jets
Specific Hazards: Thermal decomposition produces hazardous gases including nitrogen oxides, sulfur oxides, and carbon monoxide
Protective Equipment: Firefighters use self-contained breathing apparatus and protective clothing
Special Precautions: Avoid breathing fumes from combustion, contain runoff
Personal Precautions: Use personal protective equipment as required, ventilate area, avoid generation of dust, stop source of spill if safe
Environmental Precautions: Prevent entry into sewers or water systems, notify authorities in case of large discharge
Methods for Clean-Up: Sweep up dry material, avoid creating dust, transfer material to suitable container for disposal, clean surfaces with water after collection
Disposal: Refer to disposal considerations
Handling: Avoid dust formation, use local exhaust ventilation if necessary, wash hands after use, keep separate from incompatible substances
Storage: Store in tightly closed containers in cool, dry, well-ventilated area, protect from moisture and direct sunlight, keep away from oxidizers and reducing agents, maintain inventory record to monitor expiration
Engineering Controls: Use adequate ventilation or local exhaust to control dust, keep airborne concentrations below recommended limits
Personal Protective Equipment: Use safety glasses or goggles, wear protective gloves, use dust mask or respirator if dust is generated
Hygiene Measures: Remove and wash contaminated clothing, do not eat, drink, or smoke while using product, maintain cleanliness of work area
Appearance: Dark red to orange-red powder

Hazardous Decomposition Products: Nitrogen oxides, sulfur oxides, sodium oxides, carbon monoxide, carbon dioxide generated under fire conditions
Reactivity: Not considered reactively dangerous under normal use
Acute Toxicity: LD50 oral (rat): > 2000 mg/kg; not considered acutely toxic under normal use concentrations
Chronic Effects: Studies suggest risk of allergic response; some reports of hyperactivity in children associated with food coloring intake, though major health agencies consider intake within established ADI as safe
Skin Contact: May cause mild irritation in sensitive individuals
Eye Contact: May cause irritation
Sensitization: Possible for individuals with dye sensitivity
Carcinogenicity: Not listed as carcinogen by IARC, NTP, OSHA
Mutagenicity: Negative in most assays, occasional positive result in in-vitro systems—regulatory reviews indicate risk is low
Reproductive Toxicity: Listed studies do not indicate reproductive impacts
Ecotoxicity: Not readily biodegradable, dyes water when released, may affect aquatic environments at elevated concentrations
Persistence and Degradability: Allura Red is not easily broken down by natural biological processes, focusing attention on long-term accumulation potential
Bioaccumulation: Low bioaccumulation factor in aquatic and terrestrial species
Mobility in Soil: Water soluble, may leach to groundwater under certain conditions, but rapid dilution reduces biological risks
Other Adverse Effects: Effluent regulation for dye substances often focuses on direct discharge to water, review local wastewater requirements
Waste Disposal: Safely dispose in accordance with local, regional, and national requirements, avoid disposing large quantities in the normal waste stream
Container Disposal: Thoroughly clean before reuse or recycling, or dispose as hazardous waste
Special Precautions: Do not release into the environment, ensure material does not enter drains or natural waters
Preferred Treatment: Incineration or landfill under controlled conditions where local laws permit, use of authorized waste disposal contractors is recommended
