The molecular structure of PEG600DO combines hydrophilic polyethylene glycol (PEG) segments with lipophilic oleic acid groups. This amphiphilic structure endows it with outstanding emulsifying, dispersing, and wetting performance in various industrial formulations. It appears as a light yellow to yellow liquid and exhibits good compatibility with anionic, cationic, and nonionic systems, offering strong formulation adaptability.
In terms of performance, this product has rapid emulsification ability for various oils, waxes, and solvent systems, forming emulsions with uniform particle size and high stability. Additionally, it remains active in complex media such as acids, alkalis, and hard water, resisting hydrolysis or deactivation, and can adapt to harsh formulation environments. Its wetting and dispersing functions effectively reduce interfacial tension and assist in dispersing pigments and fillers, improving the overall uniformity of the formulation.
Regarding safety, PEG600DO is classified as a practically non-toxic substance (oral LD50 > 5000 mg\/kg), with a flash point above 150°C (closed cup). It is not flammable, explosive, or strongly corrosive, and exhibits only slight irritation to skin and eyes, making it a safer nonionic type suitable for daily chemical formulations requiring skin contact.

Cosmetics and Personal Care: Used as a primary or auxiliary emulsifier in creams, lotions, and makeup removers, imparting a fine texture and good spreadability to products, suitable for formulations such as moisturizing creams, sunscreens, and facial cleansers.
Textile Industry: Applied in synthetic fiber spinning oils and finishing auxiliaries, providing smoothness and cohesion, while also serving as an antistatic agent to reduce static buildup during fiber processing and lower breakage rates.
Metalworking Fluids: In emulsified cutting fluids, grinding fluids, and rolling oils, it plays a dual role of emulsification and lubrication, helping to improve machining accuracy and workpiece surface finish, and extending tool life.
Pesticide Formulations: As an efficient emulsifying component in pesticide emulsifiable concentrates, microemulsions, and oil-in-water emulsions, it promotes the dispersion and emulsification of active ingredients in water, ensuring uniform dispersion and stable efficacy release of the diluted solution during field application.
Industrial Cleaners: Suitable for degreasers and hard surface cleaner formulations, it enhances the emulsification and removal ability of mineral oils and greases, while its low-foaming characteristics facilitate subsequent cleaning processes.
