Product Name: Anthocyanins
Chemical Family: Flavonoid glycosides
Synonyms: Natural pigment, berry extract pigment
Molecular Formula: Variable, common forms include C15H11O+
CAS Number: 528-58-5 (common anthocyanin, Cyanidin-3-glucoside)
Recommended Use: Colorant in food, beverages, nutraceuticals, pharmaceuticals, cosmetics
Manufacturer/Supplier: Name, Address, Emergency Contact Telephone Number provided on packaging
Classification: Not classified as hazardous under current GHS or OSHA criteria
Signal Word: None
Hazard Statements: May cause mild eye irritation if exposed in powdered form. Inhalation may irritate respiratory tract. Ingestion expected to be safe in typical food amounts. Not flammable.
Pictogram: None required
Precautionary Statements: Avoid generating or inhaling dust. Avoid direct contact with eyes. Use good industrial hygiene practices.
Substance: Anthocyanins
Concentration: Typically above 90% pure in commercial extracts
Other Ingredients: Moisture (up to 10%), trace organic acids, sugars
Impurities: None expected at hazardous concentrations
Eye Contact: Rinse thoroughly with water for several minutes. Remove contact lenses if present and easy to do; continue rinsing if irritation persists.
Skin Contact: Wash affected area with soap and water. Remove contaminated clothing and wash before reuse.
Inhalation: Move person to fresh air; seek medical attention if symptoms persist, especially if powder inhaled.
Ingestion: Rinse mouth with water. No special measures needed for typical dietary exposure; seek medical attention if discomfort occurs in unusual situations.
Most Important Symptoms/Effects: Possible mild irritation to eyes or respiratory tract.
Suitable Extinguishing Media: Water spray, carbon dioxide, foam, or dry chemical
Unsuitable Extinguishing Media: None known for this material
Specific Hazards: Fine dust may form explosive mixture with air in rare conditions; pigment decomposes at high temperatures
Special Protective Equipment: Wear self-contained breathing apparatus and full protective clothing
Hazardous Combustion Products: Carbon oxides, possible organic vapors
Personal Precautions: Avoid creating and breathing dust; use personal protective equipment—safety goggles and gloves recommended for cleaning up large spills
Environmental Precautions: Prevent pigment-rich water from entering waterways in quantity; small spills unlikely to present significant risk due to biodegradability
Methods for Cleaning Up: Sweep or shovel dry material into appropriate waste container; wash area with water after cleanup; avoid excessive dust generation
Precautions for Safe Handling: Keep container tightly closed; prevent dust generation by handling gently; avoid direct contact with skin and eyes
Storage Conditions: Store in a cool, dry place, away from direct sunlight and sources of heat; use food-grade containers; protect from moisture contamination
Incompatible Materials: Strong oxidizers, acids or bases may degrade pigment
Hygiene Measures: Wash hands after handling; do not eat, drink, or smoke in processing areas
Exposure Limits: No established occupational exposure limit for anthocyanins; monitor for nuisance dust (15 mg/m³ total dust, 5 mg/m³ respirable dust for particulates not otherwise regulated)
Engineering Controls: Use local ventilation to minimize airborne pigment dust; routine lab and food industry ventilation methods sufficient
Personal Protective Equipment: For industrial processing, wear safety goggles, lab coat or aprons, gloves (nitrile preferred); dust mask recommended when handling powder in bulk
General Hygiene: Wash hands thoroughly after handling pigment; change out of contaminated clothing after work
Appearance: Fine powder or crystals, color ranges from red to purple to blue
Odor: Mild, fruity or neutral
pH: Variable (depends on water and extract medium); acidic to neutral
Melting Point: Decomposes before melting, above 200°C
Boiling Point: Not applicable (decomposes)
Solubility: Readily soluble in water and aqueous alcohol
Vapor Pressure: Negligible
Partition Coefficient (log Kow): Not measured, low due to high hydrophilicity
Flash Point: Not applicable
Explosion Limits: Not applicable
Density: 1.2–1.5 g/cm³ (solid powder form)
Stability in Solution: Sensitive to pH, light, and oxygen
Chemical Stability: Stable in original packaging and dry conditions; readily decomposes in solution when exposed to heat and light
Thermal Decomposition: Releases carbon oxides, simple organic compounds
Conditions to Avoid: Prolonged exposure to direct sunlight, elevated temperature, strong acids or bases
Incompatible Materials: Strong oxidizers, unstable light or UV-rich environments
Hazardous Decomposition Products: Carbon dioxide, trace organic acids, decomposition products at high heat
Acute Toxicity: No significant toxicity observed in animal testing; LD50 (oral, rat) > 5,000 mg/kg
Chronic Toxicity: Used extensively in foods with no established adverse effects in humans; consumed safely for centuries
Routes of Exposure: Inhalation of dust, ingestion, skin contact
Symptoms: Eye and respiratory tract irritation possible with dust; no known chronic effects
Carcinogenicity: Not listed by IARC, NTP, OSHA as carcinogen
Reproductive Toxicity: No evidence of mutagenicity or reproductive risk in animal models
Additional Information: Recognized as GRAS (Generally Recognized As Safe) for use in foods by FDA
Ecotoxicity: Low risk to aquatic life at realistic concentrations; no bioaccumulation expected
Mobility: Readily disperses in water and soil; quickly degraded by natural microbial activity
Persistence and Degradability: Rapidly biodegradable; broken down by sunlight and microbes
Bioaccumulative Potential: Low, not expected to accumulate in food chain
Other Adverse Effects: No evidence for chronic toxicity to ecosystems from normal discharge
Disposal Methods: Dispose of in accordance with local, regional, and national regulations. Small quantities may be flushed with water. Large quantities can be sent to landfill or compost as non-hazardous organic waste.
Packaging Disposal: Wash and recycle containers if possible.
UN Number: Not regulated
UN Proper Shipping Name: Not classified as dangerous goods
Transport Hazard Class: Not applicable
Packing Group: Not applicable
Environmental Hazards: Not a marine pollutant; stable for normal transport
Special Precautions: Protect from moisture and physical damage in transit
FDA: Approved as food additive; GRAS status
EU: Permitted as food coloring (E163)
OSHA/WHMIS: Not classified hazardous
TSCA: Listed
Other Regulatory Info: No threshold limit value assigned; handle according to standard workplace safety guidelines
