Hazard Identification

GHS Classification: Eyes and skin may irritate on contact, not classified as hazardous for inhalation or ingestion under typical use conditions
Signal Word: Caution
Pictograms: Exclamation mark for irritant
Hazard Statements: May cause mild skin and eye irritation
Precautionary Statements: Wear gloves, avoid direct contact with eyes, work in a ventilated area
Human Health Effects: Coloring agents of this type rarely cause serious health effects, but sensitive individuals might notice allergic symptoms
Environmental Hazards: Slow biodegradation rate, low acute aquatic toxicity reported, yet excessive disposal can color waterways and affect microfauna

Composition / Information on Ingredients

Ingredient: Laccaic acid complex
Chemical Percentage: Ranges between 90-98% active coloring component with moisture and inert natural material forming remainder
Impurities: Trace insect-derived proteins, fatty acids, and ash, seldom exceeding 2%
Additives: No intentional additives, may carry residuals from extraction processes

First Aid Measures

Inhalation: Move person away from dust or powder; seek fresh air; persistent symptoms merit medical advice
Skin Contact: Rinse skin thoroughly with soap and water, remove contaminated clothing
Eye Contact: Flush eyes for at least fifteen minutes with clean running water; medical evaluation advised if irritation holds
Ingestion: Rinse mouth, drink water, avoid forcing vomiting; seek medical assistance if discomfort continues
Symptoms to Watch: Redness, itching, mild nausea after accidental exposure, rare in most individuals

Fire-Fighting Measures

Flammability: Organic powder, combustible under strong ignition
Extinguishing Media: Water spray, CO2, dry chemical, or foam, tailored to fire situation
Hazardous Combustion Products: Possible release of carbon oxides, organic fumes
Protective Equipment: Firefighters need standard gear, breathing apparatus if smoke present
Specific Fire-Fighting Guidance: Cool containers if exposed to fire, avoid inhaling smoke, isolate fire zone

Accidental Release Measures

Personal Protections: Gloves, goggles, protective clothing, minimize dust through dampening if possible
Environmental Precautions: Keep powder out of water drains, secure loose material to limit movement
Cleanup Methods: Collect solids with scoop or shovel, wipe residuals with moist material, bag for disposal as safe industrial waste
Decontamination: Area should be washed with water after dry cleanup, remove and launder any soiled clothing

Handling and Storage

Handling Practices: Limit dust generation, do not eat, drink, or smoke near working areas, keep containers closed
Storage Recommendations: Store in cool, dry, well-ventilated spots, keep away from strong oxidizers and moisture sources
Shelf Life: Dried material remains stable for at least two years under proper conditions
Container Materials: Use tightly sealed polyethylene or glass containers, no reaction with usual packaging plastics or metals

Exposure Controls and Personal Protection

Engineering Controls: Operate in well-ventilated spaces, use dust extraction where quantities get high
Personal Protection: Gloves, safety glasses, light respirator for sensitive or high-exposure tasks
Exposure Limits: No official occupational exposure limit set, yet workplace dust should not exceed 10 mg/m³
Hygiene Measures: Wash hands after work, never reuse contaminated gloves or cloths, avoid contact with face

Physical and Chemical Properties

Physical State: Powder or crystalline solid
Color: Deep red to dark brown
Odor: Mild organic scent
pH Value: Acidic, around 2–4 in aqueous solution
Melting Point: Decomposes above 200°C
Solubility in Water: Highly soluble, forms a bright red solution
Boiling Point: Not applicable, decomposes
Density: About 1.2 g/cm³
Vapor Pressure: Negligible at room temperature
Flash Point: Not determined, not usually a vapor risk
Stability with Light: Strong color fade with UV exposure over time

Stability and Reactivity

Chemical Stability: Stable under temperatures and humidity typical of storage rooms
Reactivity Risks: Incompatible with strong oxidizing agents, may undergo slow decomposition in alkaline environments
Polymerization: No risk
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, aromatic hydrocarbons if burned
Conditions to Avoid: High heat, moisture, UV light

Toxicological Information

Acute Toxicity: Not acutely toxic by oral, dermal, or inhalation routes under usual application levels
Chronic Effects: No reliable reports of long-term illness from occupational or dietary exposure
Carcinogenicity: No IARC, NTP, or OSHA listing as carcinogenic
Skin/Eye Irritation: Sensitive skin or eyes might react; symptoms generally mild and transient
Respiratory Effects: Repeated inhalation of dust may trigger coughing or sneezing

Ecological Information

Ecotoxicity: Low toxicity to aquatic life, yet color could disrupt photosynthesis in algae if discharged in high concentration
Biodegradability: Slow; natural material, but color persists in the environment
Mobility in Soil: Water soluble, may leach if not contained
Potential for Bioaccumulation: Not considered bioaccumulative
Long-Term Effects: Large, repeated release can cause discoloration of waterways, which could impact visual and biological environments

Disposal Considerations

Waste Guidelines: Dispose in accordance with local or national regulations, avoid direct dumping in waterways or soil
Packaging Disposal: Clean containers may be recycled if local facilities permit
Safe Methods: Well-sealed, labeled bags for municipal or industrial waste manage most situations
Incineration: Suitable if efficient exhaust cleaning prevents organic fume release
Improper Disposal Risks: Can stain facility surfaces, impact aquatic environments, create visual pollution
