Chemical Name: Amaranth Red
CAS Number: 915-67-3
Concentration: Pure substance (may see minor impurities <1%)
Additives: None commonly present
Inhalation: Move person to fresh air. Seek medical attention if breathing is difficult or symptoms persist.
Skin Contact: Remove contaminated clothing. Wash thoroughly with soap and water. Seek help if irritation continues.
Eye Contact: Rinse cautiously with water for 15 minutes, lifting eyelids often. Get help if discomfort remains.
Ingestion: Rinse mouth with water. Call a poison center or doctor in case of large ingestion or symptoms.
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide.
Specific Hazards: Product does not burn easily but may emit toxic fumes like nitrogen oxides, sulfur oxides, sodium oxides when heated.
Protective Equipment for Firefighters: Use self-contained breathing apparatus, full protective clothing.
Personal Precautions: Wear protective equipment including gloves, goggles, and dust mask.
Environmental Precautions: Keep out of drains, sewers or waterways. Material may be harmful in aquatic environments.
Cleanup Methods: Collect spilled material in containers for disposal. Avoid creating and inhaling dust. Use wet methods wherever practical to minimize airborne dust.
Handling: Minimize dust generation. Do not eat, drink, or smoke during use. Wash hands after handling.
Storage: Store in a cool, dry, well-ventilated area away from direct sunlight, incompatible substances (strong oxidizers), and foodstuffs. Keep containers tightly closed to prevent moisture ingress and contamination.
Engineering Controls: Work in area with adequate ventilation, preferably under extraction (fume hood) when handling large amounts.
Personal Protection: Wear protective gloves (nitrile recommended), chemical safety goggles, and a dust mask or respirator if dust forms. Wear lab coat or suitable overall.
Occupational Exposure Limits: No assigned OSHA or ACGIH limit, but minimize exposure.
Hygienic Practices: Do not touch face or rub eyes when handling. Wash hands after use.

Hazardous Decomposition Products: Can break down to nitrogen oxides, sulfur oxides, sodium oxides when heated to decomposition.
Acute Toxicity: LD50 (oral, rat): >2000 mg/kg
Irritation: May cause mild skin and eye irritation.
Sensitization: Not classified as skin sensitizer.
Carcinogenicity: Evidence from animal studies suggests possible cancer risk. Regulatory agencies in several countries banned or restricted use in food.
Mutagenicity: Some positive results in animal studies.
Chronic Effects: Prolonged oral exposure could affect the liver and kidneys based on animal data.
Aquatic Toxicity: May be harmful to aquatic organisms at high concentrations. Fish LC50 (96 hr): typically >100 mg/l.
Persistence and Degradability: Slow to degrade; persists in environment.
Bioaccumulative Potential: Low, due to high water solubility and low log Kow.
Mobility in Soil: Highly mobile; material dissolves easily and may reach water systems.
Waste Disposal: Must follow local, regional, and national regulations. Pass unused material to recognized chemical disposal facility.
Container Disposal: Rinse container before recycling or disposal. Avoid disposal to landfill or sewage unless permitted.
