Precautions for Using Peregal O-80?

Peregal O-80 is a non-hazardous substance with low safety risks, but standard operating procedures should still be followed, with emphasis on personal protection, proper storage, and emergency preparedness.

Detailed Description

Peregal O-80 (C16-18 fatty alcohol polyoxyethylene (80) ether) is a high-polymerization nonionic surfactant with extremely low acute oral toxicity (rat LD50 > 5000 mg/kg), non-irritating to skin and eyes, and not classified as a dangerous chemical. However, in industrial environments, standard chemical safety practices should still be observed to avoid unnecessary direct contact and inhalation, ensuring the long-term health and safety of operators.

Special attention should be paid to its physical form: Peregal O-80 is a white to pale yellow flake or waxy solid at room temperature, which may soften at higher temperatures and harden at lower temperatures. Therefore, the material state should be confirmed before use, and the temperature should be adjusted appropriately for convenient handling and feeding, while avoiding extreme temperatures and drastic temperature changes that may affect product performance.

In addition, due to its excellent biodegradability (OECD 301B test: > 60% degradation in 28 days) and low toxicity to aquatic organisms, it should still be prevented from entering sewers and natural water bodies during large-scale use or spills, fulfilling environmental protection responsibilities.

Precautions for Use

📌 Personal Protective Equipment (PPE)

• Respiratory Protection: In poorly ventilated or high concentration dust/aerosol environments, wear a certified particulate respirator.
• Hand Protection: Wear chemical-resistant gloves (e.g., nitrile rubber gloves), inspect regularly, and replace as needed.
• Eye Protection: Wear chemical safety goggles to prevent splashes into eyes.
• Skin and Body Protection: Wear conventional chemical protective clothing; if there is a risk of significant contact, wear impermeable aprons and protective boots.

📌 Operational Precautions

• Use only in well-ventilated areas, avoid generating and inhaling dust/aerosols.
• Avoid direct contact with eyes, skin, and clothing.
• Do not eat, drink, or smoke during work.
• Thoroughly wash hands and exposed skin after handling.
• Contaminated clothing must be washed before reuse.
• Eyewash stations and emergency showers should be available in the workplace.

📌 Storage Conditions

• Store in a cool, dry, well-ventilated dedicated warehouse with a bunded floor or leak-proof design.
• Keep ambient temperature between 0°C to 40°C, relative humidity not exceeding 70%.
• Keep containers tightly closed; reseal immediately after opening. Use original or compatible containers (e.g., stainless steel, HDPE).
• Keep away from strong oxidizers (e.g., peroxides, permanganates), strong acids, strong bases, and other incompatible substances.
• Keep away from food, beverages, and animal feed; avoid direct sunlight and rain.
• Follow the "first-in, first-out" inventory management principle, and use within the shelf life.

📌 Emergency Procedures

• Skin Contact: Immediately remove contaminated clothing, rinse with plenty of flowing water and soap for at least 15 minutes; seek medical attention if discomfort occurs.
• Eye Contact: Rinse with plenty of water or saline for at least 15 minutes (if wearing contact lenses, remove after 5 minutes of rinsing), then seek immediate medical attention.
• Inhalation: Move the person to fresh air, keep respiration unobstructed; seek medical attention if discomfort occurs.
• Ingestion: Rinse mouth with water, do not induce vomiting (unless instructed by medical personnel), drink 200-300 ml of water to dilute, and seek immediate medical attention.
• Spill Response: For small spills, absorb with inert absorbent material (sand, diatomaceous earth, etc.) and shovel into a sealed container; for large spills, pump into recovery containers. Prevent spills from entering sewers and water bodies.
• Firefighting: Product is not easily flammable; use water fog, alcohol-resistant foam, dry powder, or carbon dioxide. Firefighters should wear self-contained positive-pressure breathing apparatus.

📌 Disposal

• Priority should be given to recycling or disposal at authorized chemical incineration facilities.
• Contaminated packaging should be emptied, cleaned, and then recycled or disposed of according to material type.
• Do not mix with general industrial waste or household waste; do not discharge into sewers or environmental waters.
• Disposal must comply with all applicable local, national, and international regulations.

Technical Parameters

Application Recommendations

With its high HLB value, Peregal O-80 is particularly suitable for constructing O/W emulsion systems. In textile dyeing and printing, it is used as a leveling agent and penetrant; it is recommended to prepare an aqueous solution at a certain concentration before addition. In cosmetic creams and lotion formulations, it can be used as a primary or auxiliary emulsifier, and can be combined with other low-HLB emulsifiers for better emulsification. In pesticide formulations and industrial cleaning formulations, dosage should be adjusted according to the pH and electrolyte content of the system, taking advantage of its excellent tolerance under acidic, alkaline, and high-hardness water conditions.
