PEG400DO (Polyethylene Glycol 400 Dioleate, CAS: 9004-96-0) is a nonionic surfactant with excellent emulsifying, dispersing, and wetting properties, showing good tolerance to acidic and alkaline environments and hard water conditions. The following application information is compiled based on authoritative data from the Guoli Chemical product database.
With its balanced hydrophilic-lipophilic properties, it offers flexible compatibility and can be combined with anionic, cationic, and other nonionic systems, providing stable performance in various industrial and consumer product formulations.
| Industry | Specific Process\/Use | Functional Role |
|---|---|---|
| Textile industry | Synthetic fiber spinning oil | Provides lubricity and antistatic properties, preventing fiber damage during drawing and winding |
| Industrial lubrication | Water-soluble cutting fluids, hydraulic fluids, extreme pressure lubricants | Efficient emulsifier and rust inhibitor, stabilizes oil phase dispersion, extends fluid life |
| Metalworking | Turning, milling, grinding, stamping | Emulsifier and wetting agent, promotes oil-in-water emulsion formation, reduces tool wear |
| Personal care | Facial cleanser, body wash, makeup remover, shampoo | Mild emulsifying and emollient ingredient, cleans while keeping skin moisturized |
| Agricultural chemicals | Pesticide emulsifiable concentrate (EC), emulsion in water (EW), microemulsion (ME) | Enhances dispersion stability of active ingredients and target wetting\/spreading ability, improving efficacy |
| Others | Pigment dispersant, ink additive, industrial cleaner | Advantages of multifunctional surfactant |
PEG400DO has a moderate HLB value, making it especially suitable for formulations that require a balance of hydrophilic and lipophilic properties. It can serve as a key component in textile oils; in metalworking fluids, it is recommended to be used synergistically with other rust inhibitors to enhance anticorrosion effects; in personal care products, it imparts a silky after-wash feel.
