PEG600MO (Polyethylene Glycol 600 Monooleate) is a nonionic surfactant produced by esterifying polyethylene glycol 600 with natural oleic acid. It possesses excellent emulsifying, wetting, dispersing, and lubricating properties and is widely used in various industries including personal care, textiles, metalworking, agrochemicals, industrial cleaning, and pharmaceuticals.

Detailed Description

PEG600MO (Polyethylene Glycol 600 Monooleate, CAS No.: 9004-96-0) is a high-performance nonionic surfactant obtained by esterifying polyethylene glycol (PEG-600) with natural oleic acid. The product typically appears as a light yellow to yellow liquid or paste. Its molecular structure contains both hydrophilic polyoxyethylene chains and lipophilic long-chain fatty acid ester groups, providing a balanced hydrophilic-lipophilic balance (HLB) characteristic.

As a nonionic surfactant, PEG600MO exhibits broad compatibility and can be effectively compounded with anionic, cationic, and amphoteric surfactants. It maintains stable performance over a wide pH range and in hard water conditions. This product combines multiple functions including emulsification, wetting, dispersion, solubilization, and lubrication. Being derived from natural fatty acids, it is relatively mild and low-irritation, making it suitable for formulations requiring skin-friendliness.

PEG600MO produced by Haian Guoli Chemical Co., Ltd. strictly adheres to industrial surfactant quality standards. The product has stable performance and can serve as an O/W emulsifier in various aqueous formulations, effectively reducing oil-water interfacial tension to form stable and fine emulsions.

Application Suggestions

With its multifunctional surface-active properties, PEG600MO has broad industrial applications in the following fields:

  • Personal Care & Cosmetics: Used as an O/W emulsifier and solubilizer in creams, lotions, makeup removers, and bath products. It helps disperse oily active ingredients evenly in water-based formulations while providing a pleasant skin feel.
  • Textile Industry: Applied as an antistatic agent and softening finishing agent. It effectively reduces the friction coefficient between fibers, imparting a soft and smooth hand feel and minimizing static buildup during processing.
  • Metalworking Fluids: Acts as an emulsifier and lubricant in cutting fluids and grinding fluids, promoting stable dispersion of oil components while providing auxiliary lubrication. This helps extend tool life and improve machined surface quality.
  • Agrochemical Formulations: Serves as an emulsifier for pesticide active ingredients, ensuring uniform dispersion in aqueous systems. It enhances the wetting and spreading ability of the spray solution, thereby improving field application efficacy.
  • Industrial Cleaners: Exhibits significant emulsifying and dispersing effects on mineral oils, vegetable oils, and animal fats. It aids in removing greasy soils and prevents redeposition of dirt.
  • Pharmaceutical Industry: Used as a solubilizer for poorly soluble drugs, improving dispersion and potentially enhancing bioavailability or formulation stability.

Precautions

  • Skin and Eye Irritation: This product may cause skin irritation (H315) and serious eye irritation (H319). Wear chemical safety goggles and nitrile or neoprene gloves during handling.
  • Respiratory Protection: May cause respiratory irritation (H335). Ensure adequate ventilation during use and avoid inhaling vapors or mists.
  • Storage Conditions: Keep containers tightly closed. Store in a cool (recommended 5–30°C), dry, and well-ventilated indoor area away from heat sources and direct sunlight. Avoid contact with incompatible materials such as oxidizers, strong acids, and strong bases.
  • Emergency Measures: In case of eye contact, flush immediately with plenty of running water for at least 15 minutes and seek medical attention. For skin contact, wash with soap and plenty of water. Always refer to the complete Safety Data Sheet (SDS) before use.
  • Packaging Containers: Use containers made of stainless steel, glass, or HDPE. Avoid prolonged contact with metals such as copper and aluminum.
