Inhalation: Move affected person to fresh air, support breathing; seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash skin with plenty of water and soap; get medical help for persistent irritation
Eye Contact: Rinse thoroughly with plenty of water for at least 15 minutes; consult a medical professional if discomfort continues
Ingestion: Rinse mouth with water, give water to drink if conscious; seek medical advice for large quantities or symptoms such as nausea
Symptoms: Mild respiratory, skin or eye irritation possible with overexposure
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Media: Strong water jets may cause dust dispersal
Specific Hazards Arising: Product dust can form explosive mixtures with air if accumulated
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective clothing
Special Procedures: Avoid inhaling combustion fumes; evacuate area if fire is large
Hazardous Combustion Products: Carbon oxides, nitrogen oxides, possibly unidentified organic compounds
Personal Precautions: Avoid inhalation; wear dust mask, gloves, and goggles
Environmental Precautions: Prevent entry into drains, surface water, soil
Methods for Cleaning Up: Gently sweep or vacuum up spillage; place material in suitable container for disposal; wash contaminated surfaces with plenty of water
Other Advice: Stop further release if safe to do so; use explosion-proof equipment if large amounts of dust may become airborne
Handling: Minimize dust generation and accumulation; use material with adequate local exhaust ventilation; avoid inhalation and prolonged skin contact; wash hands after handling
Storage Conditions: Store in tightly closed original container in a cool, dry, well-ventilated area; keep away from direct light, heat sources, and moisture
Packaging Materials: Use food-grade, airtight, opaque containers
Incompatible Materials: Strong oxidizing agents, acids
Exposure Limits: No occupational exposure limit set for riboflavin
Engineering Controls: Use local exhaust ventilation or containment when handling large quantities
Personal Protective Equipment: Safety goggles, dust mask or particulate respirator (P2/P3), protective gloves, work clothing
Hygiene Measures: Wash hands and face after handling; avoid consuming food or beverages in work area
Environmental Controls: Prevent spillage from entering water or drainage system

Melting Point: 280°C with decomposition
Boiling Point: Decomposes without boiling
Solubility: Slightly soluble in water, practically insoluble in alcohol and ether
Flash Point: Not applicable
Bulk Density: About 300–600 kg/m³
Other Data: Stable under recommended storage conditions, photosensitive
Chemical Stability: Stable under normal conditions; photosensitive and may degrade upon exposure to light
Conditions to Avoid: Exposure to strong light, heat, moisture, oxidizing agents
Incompatible Materials: Strong oxidizers, acids, alkalis
Hazardous Decomposition Products: Carbon oxides, nitrogen oxides, possible organic fumes

Acute Toxicity: Low toxicity; LD50 (oral, rat) > 10,000 mg/kg
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Skin Irritation: May cause mild irritation on prolonged or repeated contact
Eye Irritation: Mild, transient irritation possible
Respiratory Irritation: Dust may cause respiratory tract irritation
Chronic Effects: Not known to cause significant health issues at typical exposure doses
Carcinogenicity: Non-carcinogenic (IARC, NTP, OSHA do not list riboflavin as carcinogen)
Sensitization: Not expected at ingredient or product level
Ecotoxicity: Low toxicity to aquatic life; product may contribute to eutrophication in water bodies at very high concentrations
Persistence and Degradability: Biodegradable; riboflavin readily breaks down in the environment
Bioaccumulation Potential: Low potential for bioaccumulation
Mobility in Soil: Limited due to low water solubility
Other Adverse Effects: Avoid large-scale releases into watercourses to prevent nutrient overloading
