PEG600DO, full name Polyethylene Glycol 600 Dioleate (CAS: 9004-96-0), is a nonionic surfactant produced by Guoli Chemical. Its unique molecular structure contains both hydrophilic polyethylene glycol (PEG) segments and lipophilic oleic acid groups, enabling it to effectively reduce interfacial tension at the oil-water interface and form stable emulsion systems. The product appears as a light yellow to yellow liquid and exhibits good compatibility with anionic, cationic, and other nonionic surfactant systems.
This product has excellent chemical stability and remains active in complex media such as acids, alkalis, and hard water, making it resistant to hydrolysis or deactivation. It can adapt to harsh formulation environments. Moreover, PEG600DO is a relatively safe nonionic type with very low oral toxicity (LD50 > 5000 mg/kg), only mildly irritating to skin and eyes, meeting the mildness requirements for daily chemical applications.
The core performance of PEG600DO lies in its rapid and efficient emulsifying ability, forming emulsions with uniform particle size and high stability for a variety of oils, waxes, and solvent systems. Additionally, it provides auxiliary dispersing effects on pigments and fillers, significantly improving the uniformity and overall performance of formulations.
1. Cosmetics and Personal Care Products — Used as a primary or auxiliary emulsifier in creams, lotions, makeup removers, and sunscreens, providing fine texture and moisturizing feel while ensuring excellent emulsion stability.
2. Textile Industry — Applied in fiber spinning oils and finishing auxiliaries, imparting smoothness and cohesion to fibers while providing antistatic effects, effectively reducing static buildup and breakage rates during fiber processing.
3. Metalworking Fluids — In emulsified cutting fluids, grinding fluids, and rolling oils, it serves both emulsifying and lubricating functions, helping to improve machining accuracy, extend tool life, and enhance workpiece surface finish.
4. Pesticide Formulations — As an efficient emulsifying component in pesticide emulsifiable concentrates, microemulsions, and emulsions in water, it promotes uniform dispersion of active ingredients in water, enhances spreading and penetration on plant surfaces, and ensures stable release of efficacy in field applications.
5. Industrial Cleaners — Suitable for degreasers and hard surface cleaners, it enhances the emulsifying and stripping ability of mineral oils and greases. Combined with its low-foaming properties, it facilitates subsequent cleaning processes and provides certain rust protection.

In different application scenarios, the recommended addition amount of PEG600DO varies depending on the formulation system. When used as an emulsifier, the general recommended dosage is 2% to 8% of the total formulation. In metalworking fluids and pesticide formulations, it can be adjusted to 5% to 15% based on emulsification requirements. Due to its compatibility with various ionic types of surfactants, it can be flexibly combined with other emulsifiers or auxiliaries to achieve better synergistic effects. It is recommended to verify the optimal dosage through small-scale experiments during the formulation development stage.
