Content (%): 90–100
Other Ingredients: Trace amounts of residual catalyst, possible stabilizers or antioxidant below 1%
Impurities: Traces of unreacted rosin acids, possible trace metals from natural sources

First Aid Measures

Inhalation: Move affected person to fresh air; if symptoms persist such as irritation or coughing, seek medical attention
Eye Contact: Rinse carefully with water for 15 minutes; remove contact lenses if present; continue rinsing and consult a doctor if irritation develops
Skin Contact: For contact with hot/melted material, cool area with running water; do not attempt to remove solidified product; seek immediate medical care
Ingestion: Rinse mouth, drink water to dilute; do not induce vomiting; consult physician if large quantities are swallowed
Main Symptoms: Redness, itching, coughing, or irritation from dust or fume exposure
Advice for Medical Professionals: Treat symptomatically; burns from hot resin should be managed per standard burn protocols

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, foam, CO2, water spray (avoid use of direct water streams on molten material)
Unsuitable Media: Direct water jet applied to hot material may cause splattering
Special Hazards: Resin can decompose at high temperature releasing irritant and flammable fumes
Protective Equipment: Self-contained breathing apparatus, full protective suit for chemical fires
Fire Fighting Instructions: Remove containers from fire area if safe; cool adjacent containers with water spray
Combustion Products: Carbon monoxide, carbon dioxide, acrid smoke, possible trace of phenolic compounds

Accidental Release Measures

Personal Precautions: Use personal protection—gloves, goggles, dust mask when appropriate
Environmental Precautions: Prevent bulk entry into waterways or drains; notify authorities if large spillage may affect ground water
Methods for Cleaning Up: Sweep or shovel solid resin into suitable closed containers for disposal; for molten spills, allow to solidify, then remove mechanically
Safe Handling of Residues: Dispose of residue using local hazardous waste practices
Engineering Controls: Ventilate area to remove dust or fumes; avoid breathing dust

Handling and Storage

Handling: Minimize dust generation; use local exhaust where dust or fume possible; keep away from ignition sources
Storage: Store in cool, dry, well-ventilated space away from oxidizers and strong acids; maintain temperature below 35°C to prevent clumping or softening
Packaging: Use sealed, labeled containers; avoid metal containers prone to corrosion
Incompatible Materials: Avoid contact with strong oxidizing agents; acids and alkalis can degrade material
General Hygiene: Wash hands thoroughly after handling; avoid eating, drinking, or smoking near handling area

Exposure Controls and Personal Protection

Occupational Exposure Limits: No established occupational exposure limit for rosin ester dust
Engineering Controls: Local exhaust ventilation or general mechanical ventilation where dust is generated
Personal Protective Equipment: Safety goggles, chemical-resistant gloves, long-sleeved clothing, dust mask or respirator where airborne concentrations may approximate nuisance dust limits
Thermal Protection: Use heat-resistant gloves and face shield for handling molten product
Respiratory Protection: Use particulate respirator if handling large quantities of powder or when ventilation is inadequate
Environmental Controls: Avoid generating dusty conditions; control release via proper containment

Physical and Chemical Properties

Appearance: Solid, amber to light yellow, glassy flakes, pastilles, or chunks
Odor: Slight resinous or pine-like fragrance
pH: Not applicable (water insoluble solid)
Melting/Softening Point: Typically 80°C to 120°C
Boiling Point: Not applicable; decomposes above 250°C
Flash Point: Greater than 220°C (open cup)
Autoignition Temperature: Above 300°C
Solubility in Water: Insoluble
Solubility in Solvents: Soluble in alcohols, esters, aromatic and aliphatic hydrocarbons
Vapor Pressure: Negligible at ambient temperature
Relative Density: Approximately 1.05–1.10
Explosive Properties: Not prone to explosion under normal circumstances
Evaporation Rate: Not applicable for solid

Stability and Reactivity

Chemical Stability: Stable under typical storage and handling conditions
Decomposition: Heating above 250°C induces decomposition, releasing smoke and irritant gases
Possibility of Hazardous Reactions: Contact with strong oxidants or acids can cause rapid decomposition or release of acidic fumes
Incompatibility: Strong oxidizers, strong acids and bases, reducing agents
Conditions to Avoid: Overheating, open flame, prolonged exposure to high temperatures, moisture ingress
Hazardous Byproducts: Carbon monoxide, carbon dioxide, small fractions of formaldehyde and organic acids when burned

Toxicological Information

Acute Toxicity: Expected to have very low acute oral and dermal toxicity
Skin Contact: May provoke irritation or sensitization in sensitive individuals, especially from dust or molten material
Eye Contact: Particulate matter can cause mechanical irritation; severe injury possible from molten resin
Inhalation: Inhalation of dust or fume can irritate throat and respiratory tract; exposures above nuisance threshold may aggravate asthma
Ingestion: Unlikely to be harmful in small amounts; large exposures may cause stomach upset
Chronic Effects: No evidence for mutagenicity, carcinogenicity, or reproductive toxicity at exposure levels typical for industrial applications
Medical Conditions Aggravated: Individuals with pre-existing allergies or asthma may experience increased symptoms

Ecological Information

Aquatic Toxicity: Material not acutely toxic; large releases may mechanically foul surface water or sediment
Persistence and Degradability: Slowly biodegradable in soil and water; does not accumulate in biota
Bioaccumulation Potential: Expected to be low; poorly soluble materials do not readily enter food chain
Mobility in Soil: Low mobility due to hydrophobic nature, binds readily to sediment and organic matter
Other Environmental Hazards: Physical impact from large debris may affect aquatic flora and fauna
Avoidance: Prevent large scale entry to natural ecosystems by immediate containment of spills

Disposal Considerations

Waste Treatment Methods: Collect and dispose of in accordance with local, regional, and national regulations; landfilling or incineration preferred depending on volume
Do Not: Dispose to sewer or surface water bodies
Waste Code: Non-hazardous industrial waste designation in most jurisdictions
Packaging: Empty containers should be thoroughly cleaned or can be recycled according to local requirements; contaminated packaging handled as product waste
