PEG 400 Monooleate
PEG 400 Monooleate (PEG 400 MO) is a multifunctional non-ionic surfactant and emulsifier. Compared to lower molecular weight PEG oleates, PEG 400 MO offers increased water dispersibility and is commonly used where emulsification, wetting, detergency, and dispersion properties are required.
With an HLB of 11.3, PEG 400 MO is generally suited to oil-in-water (O/W) emulsification and water-dispersible formulation systems. It is widely used across water treatment, lubrication, textile, industrial, and technical applications.
