PEG600DO, full name Polyethylene Glycol 600 Dioleate (PEG-600 Dioleate), belongs to the category of nonionic surfactants. Its molecular structure contains both hydrophilic polyethylene glycol (PEG) segments and lipophilic oleic acid groups. This unique amphiphilic structure allows it to efficiently orient at the oil-water interface, significantly reduce interfacial tension, and exert excellent emulsifying effects.
The product appears as a light yellow to yellow liquid and shows good compatibility with anionic, cationic, and other nonionic surfactant systems. At the same time, PEG600DO possesses excellent chemical stability, remaining active in complex media such as acids, alkalis, and hard water, resisting hydrolysis or deactivation, and adapting to various harsh industrial formulation environments. Its safety profile is also notable, with extremely low oral toxicity (rat LD50 > 5000 mg/kg), making it a practically non-toxic substance.
As a key product of Guoli Chemical, PEG600DO, with its high emulsifying power, multifunctional wetting and dispersing properties, and mild low-irritation characteristics, plays a critical role in many fields such as cosmetic creams and lotions, chemical fiber spinning oils, metalworking fluids, pesticide formulations, and industrial cleaning agents.

Cosmetics and Personal Care Products: Used as a primary or auxiliary emulsifier in creams, lotions, sunscreens, makeup removers, and cleansing creams, imparting a fine texture and good spreadability. Recommended dosage depends on the formulation system, typically 1% to 5%.
Textile Industry: Suitable for chemical fiber spinning oils and finishing auxiliaries, providing smoothness and cohesion, and also serving as an antistatic agent, effectively reducing static buildup and breakage during fiber processing.
Metalworking Fluids: Performs dual functions of emulsification and lubrication in formulations of emulsified cutting fluids, grinding fluids, and rolling oils, helping to improve machining accuracy, workpiece surface finish, and extend tool life.
Pesticide Formulations: As an efficient emulsifying component in pesticide emulsifiable concentrates, microemulsions, and emulsion concentrates, ensuring uniform dispersion and stable efficacy release of the dilution during field application, enhancing spread and penetration on plant surfaces.
Industrial Cleaning Agents: Suitable for degreasers and hard surface cleaner formulations, enhancing the emulsification and removal of mineral oils and greases. Its low foaming property facilitates subsequent cleaning processes.
