Peregal O-80 (fatty alcohol polyoxyethylene ether) is identified as a non-hazardous substance under the GHS classification system, requiring no pictograms or signal words for labeling. Its acute oral toxicity is extremely low (rat LD50 > 5000 mg/kg, practically non-toxic), acute dermal toxicity is also very low (rabbit LD50 > 2000 mg/kg), it is non-irritating to skin and eyes, negative in skin sensitization tests, and negative in genotoxicity tests (Ames test, etc.). This indicates that under normal industrial use conditions, the health risk of Peregal O-80 to humans is at a very low level.
Nevertheless, as an industrial nonionic surfactant, the following precautions should still be taken during use: The product may generate dust or aerosols during handling, and inhalation should be avoided. In poorly ventilated or high-concentration environments, it is recommended to wear a certified particulate respirator. Avoid direct contact with eyes, skin, and clothing; wear chemical-resistant protective gloves (e.g., nitrile rubber gloves) and chemical safety goggles during operation, and wear chemical protective clothing when necessary.
In terms of environmental protection, Peregal O-80 exhibits low toxicity to aquatic organisms (fish, daphnia LC50/EC50 > 100 mg/L), is readily biodegradable (OECD 301B test: >60% rapid biodegradation in 28 days), and is not classified as PBT or vPvB. However, precautions should still be taken to prevent spills from entering sewers, surface water, and groundwater systems. In case of spills, inert absorbent materials (e.g., sand, diatomaceous earth) should be used for collection.
| Safety Category | Specific Requirements |
|---|---|
| Engineering Controls | Maintain good ventilation in the workplace; install local exhaust ventilation for processes generating dust or spray; equip the operation area with eyewash stations and emergency showers |
| Respiratory Protection | In poorly ventilated or high-concentration environments, wear a certified particulate respirator |
| Hand Protection | Wear chemical-resistant protective gloves, recommended nitrile rubber gloves; inspect regularly and replace as needed |
| Eye Protection | Wear chemical safety goggles to prevent splashes into eyes |
| Skin Protection | Wear standard chemical protective clothing; when there is a risk of extensive contact, wear impermeable aprons and protective boots |
| Storage Temperature | Keep ambient temperature between 0°C and 40°C, relative humidity not exceeding 70% |
| Incompatible Substances | Keep away from strong oxidizers (peroxides, permanganates, etc.), strong acids, and strong bases |
Immediately remove contaminated clothing and flush the affected area thoroughly with plenty of running water and soap for at least 15 minutes. If skin irritation or discomfort occurs, seek medical advice.
Immediately flush eyes with plenty of water or saline solution for at least 15 minutes, keeping eyelids open. If wearing contact lenses and easy to remove, remove them after 5 minutes of flushing. Seek medical attention immediately after flushing.
Move the affected person to fresh air and keep breathing unobstructed. If discomfort occurs, seek medical attention immediately.
Rinse mouth with water; do not induce vomiting unless directed by medical personnel. Immediately have the person drink 200-300 mL of water to dilute stomach contents. Do not give anything by mouth to an unconscious person. Seek medical attention immediately and show the product safety data sheet or label to the doctor.
Isolate the spill area and restrict non-emergency personnel from entering. For small spills, absorb with inert absorbent material (sand, diatomaceous earth, universal binder) and collect into a sealed container. For large spills, transfer to recovery containers using pumps or explosion-proof tools. Prevent spills from entering sewers and water bodies. Clean the contaminated area with soapy water and plenty of water.
Peregal O-80 itself is not flammable, but packaging materials may burn and release toxic fumes. Suitable extinguishing media include water spray, alcohol-resistant foam, dry powder extinguisher, or carbon dioxide. Do not use a strong water jet. Firefighters should wear self-contained positive-pressure breathing apparatus and full protective equipment.
