Peregal O-50/100 is a high polymerization degree fatty alcohol polyoxyethylene ether nonionic surfactant, used as textile dyeing leveling agent, glass fiber emulsifier and industrial detergent.
Peregal O-50/100 belongs to the fatty alcohol polyoxyethylene ether (AEO) series of nonionic surfactants, chemically named polyethylene glycol fatty alcohol ether. It is produced by addition polymerization of natural fatty alcohol (C16-C18) with ethylene oxide (EO). When the EO addition number is approximately 50, it corresponds to Peregal O-50; when approximately 100, it corresponds to Peregal O-100.
Peregal O-50 is a white to slightly yellow waxy solid, readily soluble in hot water and dispersible in cold water. Peregal O-100 is a white to slightly yellow flake or granular solid, readily soluble in water forming a clear solution. Both are non-toxic, non-irritating and exhibit good biodegradability. They are high-performance O/W nonionic emulsifiers, dispersants and leveling agents, widely used in textile dyeing, household chemicals, pesticide formulations and emulsion polymerization.
Their core advantage lies in the extremely long polyoxyethylene chains which impart very high hydrophilicity and outstanding steric stabilization, producing emulsions and dispersions with fine particle size and excellent stability, particularly suitable for industrial formulations requiring electrolyte resistance, high-temperature tolerance and long-term stability.
Dissolution Guide: Slowly add the product to hot water at 40-60°C with continuous stirring until completely dissolved, then incorporate into the formulation and mix thoroughly. Peregal O-100 can also be directly dispersed and dissolved in room temperature aqueous solutions. Conduct small-scale trials to determine the optimal addition amount and dissolution conditions for specific processes.
With ultra-long polyoxyethylene chains providing extremely high hydrophilicity and steric stabilization, Peregal O-50/100 offers outstanding performance in demanding applications:

According to GHS, Peregal O-50/100 (fatty alcohol polyoxyethylene ether) is not classified in any physical hazard category. Health hazards: Acute oral toxicity Category 5 or not classified (LD50>2000 mg/kg, rat); no skin corrosion/irritation (prolonged or high-concentration contact may cause mild irritation); no serious eye damage/irritation (may cause mild discomfort); no respiratory or skin sensitization. Environmental hazards: Low toxicity to aquatic organisms (EC50/LC50>100 mg/L), not classified as acute aquatic hazard. No other known hazards.
Respiratory: No special protection typically required. If high concentrations of aerosol or dust are generated, wear particulate filter mask (FFP2/N95).
Hand: Wear chemical protective gloves such as nitrile or neoprene. Wash hands thoroughly after contact.
Eye: Wear chemical safety goggles or face shield to prevent splashing.
Skin and Body: Wear standard work clothing. If heavy splashing may occur, wear impermeable apron or protective clothing.
Inhalation: Move victim to fresh air and keep comfortable for breathing. Seek medical attention if symptoms persist.
Skin: Immediately remove contaminated clothing. Flush skin with plenty of water and soap for at least 15 minutes. If irritation or rash occurs, seek medical attention. Wash contaminated clothing before reuse.
Eyes: Rinse immediately with plenty of water or saline solution, keeping eyelids open, for at least 15 minutes. If persistent pain, tearing or redness occurs, seek ophthalmological treatment.
Ingestion: Rinse mouth. Do not induce vomiting. Drink 1-2 glasses of water to dilute. Seek medical attention if discomfort occurs. Show this safety data to the physician.
Most important symptoms/effects: May cause mild gastrointestinal discomfort or diarrhea. No known acute toxic severe effects.
Extinguishing media: Use water fog, alcohol-resistant foam, dry powder or carbon dioxide. Avoid direct water jets to prevent splashing and spreading.
Special protection: Firefighters must wear self-contained breathing apparatus and full protective clothing.
Hazardous combustion products: Carbon monoxide, carbon dioxide and possibly irritating or toxic fumes.
