Chemical Name: Pentaerythritol Ester of Hydrogenated Rosin
CAS Number: 8050-26-8
Concentration: 98–100%
Impurities: Trace (<1%) acids and unreacted rosin
Additives: No hazardous additives present
Eye Contact: Flush with plenty of water for at least 10 minutes. Remove contact lenses if present and easy to do. Seek medical attention if irritation persists.
Skin Contact: Wash with soap and water. Remove contaminated clothing. Get medical advice if symptoms occur.
Inhalation: Move the person to fresh air. Support breathing as needed. Get medical advice if symptoms develop.
Ingestion: Rinse mouth with water. Do not induce vomiting. Contact a healthcare provider if discomfort develops or persists.
Extinguishing Media: Use foam, carbon dioxide, dry chemical powder, or water spray. Avoid direct water jets on hot resins as splattering may occur.
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, possible irritating fumes
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear.
Special Procedures: Cool containers with water if exposed to fire; do not allow contaminated water to enter sewers or waterways.
Personal Precautions: Wear suitable protective equipment including gloves and eye protection. Avoid breathing dust.
Environmental Precautions: Prevent spillage from entering drains or watercourses. Contain and collect spilled material using non-combustible absorbent.
Cleanup Methods: Sweep up and place in a suitable container for disposal. Ventilate area to remove dust.
Handling: Avoid creating dust. Wear suitable protective clothing. Handle in well-ventilated areas.
Hygiene Measures: Wash hands thoroughly after handling. Do not eat, drink, or smoke while using.
Storage Conditions: Store in a dry, cool, and well-ventilated place. Keep containers closed and away from sources of ignition or strong oxidizing agents.
Incompatible Materials: Strong acids, strong bases, oxidizers
Occupational Exposure Limits: No specific limits for this substance. Maintain general dust exposure below 10 mg/m³ for nuisance dust.
Engineering Controls: Use process enclosures or local ventilation to minimize dust.
Personal Protection: Safety glasses and gloves recommended. For large-scale operations or where dust is present, use a dust mask or respirator. Use protective clothing to minimize skin contact.
Environmental Controls: Avoid release to the environment by using spill containment and proper waste management.
Appearance: Pale yellow to amber solid, hard resinous lumps or pastilles
