PEG600MO is produced by esterification of polyethylene glycol (PEG-600) with natural oleic acid. Its molecular structure contains both hydrophilic polyoxyethylene chains (PEG chains) and lipophilic long-chain fatty acid ester groups (oleic acid groups). This unique amphiphilic structure gives it a balanced hydrophilic-lipophilic balance, effectively reducing interfacial tension between oil and water phases, forming stable and fine dispersions in emulsion systems.
As a nonionic surfactant, PEG600MO has good compatibility with anionic, cationic, and amphoteric surfactants, offering high flexibility in formulation design. Additionally, its nonionic nature provides excellent resistance to acids, alkalis, and hard water—it maintains stable emulsifying and dispersing properties over a wide pH range and under high-hardness water conditions, without being easily deactivated by calcium/magnesium ions or pH changes. This is particularly important in industrial applications.
Furthermore, this product features "multi-effect in one" functionality. A single component can simultaneously perform emulsification, wetting, dispersion, solubilization, and lubrication, helping to simplify formulations and reduce overall costs. Sourced from natural oleic acid, the product is relatively mild with low irritation, making it especially suitable for applications with high skin-friendliness requirements, such as personal care products.

Personal Care and Cosmetics: Used as an O/W emulsifier and solubilizer, suitable for creams, lotions, makeup removers, and bath products, helping to uniformly disperse oil-soluble active ingredients in water-based formulations while improving skin feel and product stability. Recommended for use as a primary or auxiliary emulsifier in formulations.
Textile Industry: As an antistatic agent and softener, it effectively reduces friction coefficient between fibers, imparting a soft and smooth feel to fabrics. Suitable for finishing processes of various fibers such as cotton and synthetic fibers.
Metalworking Fluids: Acts as an emulsifier and lubricant in cutting fluids and grinding fluids, promoting stable dispersion of oil components in water while providing auxiliary boundary lubrication, helping to extend tool life and improve machined surface quality.
Pesticide Formulations: Used as a pesticide emulsifier in emulsifiable concentrates and emulsion concentrates to help uniformly disperse active ingredients, improve wetting and spreading ability of the spray, and enhance field application efficacy.
Industrial Cleaning and Pharmaceuticals: Shows significant emulsifying and dispersing effects on mineral oils and animal/vegetable oils in industrial cleaning agents. In the pharmaceutical field, it can serve as a solubilizer for poorly soluble drugs, improving dispersion and bioavailability.
