PEG600MO is a nonionic surfactant produced by esterifying Polyethylene Glycol 600 with natural oleic acid. It possesses both hydrophilic and lipophilic properties, with a moderate HLB value, making it a well-balanced O/W type emulsifier. Its nonionic nature allows good compatibility with anionic, cationic, and amphoteric surfactants, maintaining stable performance over a wide pH range and in hard water conditions, thus offering a broad range of applications.
In formulation processes, PEG600MO effectively reduces oil-water interfacial tension, aiding in the preparation of stable, fine emulsion systems. It also provides auxiliary functions such as wetting, dispersing, solubilizing, and lubricating, allowing a single component to meet multiple process requirements, which helps simplify formulation design and reduce overall costs.
Derived from natural fatty acids, this product is relatively mild and has low skin irritation, making it popular in fields with high safety requirements such as personal care and pharmaceuticals. The following sections detail its specific application processes by industry.
| Industry | Core Function | Typical Processes and Products |
|---|---|---|
| Personal Care & Cosmetics | O/W Emulsifier, Solubilizer, Emollient | Creams, lotions, cleansing oils, facial cleansers, bath products; helps uniformly disperse oily active ingredients in water-based formulations, improving product texture and stability |
| Textile Industry | Antistatic Agent, Softening Finishing Agent | Used in the finishing process of various fibers to reduce inter-fiber friction coefficient, impart a soft and smooth feel to fabrics, and minimize static buildup during processing |
| Metalworking Fluids | Emulsifier, Lubricant | In cutting fluids, grinding fluids, and other metalworking media, it promotes stable dispersion of oil components in water, providing boundary lubrication, helping extend tool life and improve machined surface quality |
| Pesticide Formulations | Pesticide Emulsifier | In emulsifiable concentrates (EC), oil-in-water emulsions (EW), etc., it helps uniformly disperse and emulsify pesticide active ingredients, enhancing wetting, spreading, and penetration capability on target surfaces |
| Industrial Cleaners | Nonionic Surfactant Component | In water-based hard surface cleaner formulations, it exhibits significant emulsification and dispersion effects on mineral oils, animal and vegetable oils, aiding in the removal of greasy soils and preventing soil redeposition |
| Pharmaceutical Industry | Drug Solubilizer | Improves the solubility and dissolution rate of poorly soluble drugs, enhancing the bioavailability of pharmaceutical formulations; suitable for oral and topical drug systems |
In formulation design, PEG600MO has a wide recommended temperature range and can be effectively dispersed and emulsified at moderate to low temperatures. For O/W emulsion systems, the recommended dosage is typically between 1% and 5%, with specific amounts adjusted based on the oil phase ratio and desired emulsion viscosity. When combined with anionic or cationic surfactants, its nonionic nature can provide synergistic effects, improving the stability and functionality of the overall formulation.
