Hazard Statements: Causes skin and eye irritation, may cause respiratory irritation
Precautionary Statements: Avoid breathing fumes or mist, wear protective gear, wash hands thoroughly

3. Composition / Information on Ingredients

Main Ingredient: Rosin, Ester with Glycerol or Pentaerythritol, concentration >90%
Other Components: Trace levels of unreacted rosin acids, residual catalysts, antioxidants, stabilizers, mixture contains no hazardous impurities at significant levels

4. First Aid Measures

Inhalation: Move affected person to fresh air, seek medical attention for respiratory symptoms like coughing or shortness of breath
Skin Contact: Remove contaminated clothing, wash skin with soap and water, consult healthcare if irritation persists
Eye Contact: Rinse eyes with water for at least 15 minutes, hold eyelids apart, remove contact lenses, seek medical advice if irritation continues
Ingestion: Rinse mouth thoroughly, do not induce vomiting, get medical attention if unwell or if large amounts have been swallowed

5. Fire-Fighting Measures

Suitable Extinguishing Media: Use foam, dry chemical, or carbon dioxide, avoid direct water streams as product can float and spread fire
Unsuitable Media: Water jets may spread burning product
Specific Hazards: Vapors can form explosive mixtures with air at high temperatures, decomposition may release irritating fumes like carbon monoxide, carbon dioxide, and acrolein
Protective Equipment: Firefighters should wear full protective clothing and self-contained breathing apparatus
Fire Fighting Instructions: Move containers from fire area if safe, use water spray to cool exposed surfaces, dike runoff to prevent environmental contamination

6. Accidental Release Measures

Personal Precautions: Wear gloves, goggles, protective clothing, avoid breathing vapor or mist
Environmental Precautions: Prevent run-off into drains, soil, and surface waters
Methods for Cleanup: Contain spill using non-combustible absorbent like sand or earth, collect in containers for disposal, clean residual with detergent and water, ventilate area well

7. Handling and Storage

Handling: Avoid contact with skin and eyes, use only with adequate ventilation, prohibit smoking and open flames near storage and use areas, ground all equipment to prevent static discharge
Storage: Store in cool, dry, well-ventilated place, keep containers tightly closed when not in use, avoid storing near strong oxidizers, bases, acids; segregate from food and animal feed; use original containers

8. Exposure Controls and Personal Protection

Engineering Controls: Use local exhaust to maintain airborne levels below exposure limits, provide eyewash and safety showers in work area
Personal Protective Equipment: Wear chemical-resistant gloves, safety goggles, protective clothing, if ventilation is inadequate wear approved respirator suitable for organic vapor
Exposure Guidelines: No established Occupational Exposure Limits for rosin ester, follow good industrial hygiene practices, minimize exposure to all product constituents

9. Physical and Chemical Properties

Conditions to Avoid: Excessive heat, open flames, strong oxidizing agents
Incompatible Materials: Acids, bases, strong oxidizers
Hazardous Decomposition Products: May release carbon oxides, acrolein, and other toxic fumes if burned or overheated

11. Toxicological Information

Acute Toxicity: Low oral and dermal toxicity, ingestion unlikely to pose major health hazard in small amounts
Skin Corrosion/Irritation: May cause mild to moderate irritation, prolonged or repeated contact increases risk
Serious Eye Damage/Irritation: May cause mild to moderate eye irritation
Respiratory or Skin Sensitization: Rare cases of allergic dermatitis reported after repeated contact with rosin or esters
Chronic Toxicity: No long-term health effects known from typical exposure
Carcinogenicity: Not classified by IARC, NTP, or OSHA as carcinogenic
Additional Information: No evidence shows mutagenicity or reproductive toxicity at typical occupational exposure levels

12. Ecological Information

Ecotoxicity: Product considered moderately toxic to aquatic life, especially in large spills, can cause oxygen depletion in water
Persistence and Degradability: Natural rosin esters degrade slowly, breakdown increases in sunlight and soil
Bioaccumulative Potential: Expected to have low to moderate bioaccumulation
Mobility in Soil: Absorbs to soil and sediment, moves slowly through groundwater
Other Adverse Effects: No chronic ecosystem effects expected with responsible use, prevent large or repeated releases

13. Disposal Considerations

Waste Treatment Methods: Dispose of via approved incineration or landfill, in accordance with local, regional, and national regulations
Product Waste: Avoid discharge to watercourses, collection preferred in sealed, labeled containers
Contaminated Packaging: Empty containers may contain residues, triple rinse, dispose as hazardous waste if not reusable
Precautions: Do not mix with other waste streams, avoid discharge to drains or surface water

14. Transport Information
