PEG200MO, full name Polyethylene Glycol 200 Monooleate (CAS number: 9004-96-0), also known as PEG-4 Oleate, Polyethylene Glycol-4 Oleate, Polyoxyethylene (4) Monooleate, etc. This product is prepared by esterification of polyethylene glycol (PEG-200) with natural oleic acid and belongs to nonionic surfactants.
As a classic nonionic surfactant, PEG200MO possesses excellent emulsifying ability, effectively reducing oil-water interfacial tension to form a stable and fine O\/W emulsion system. Meanwhile, its outstanding wetting and dispersing properties enable rapid spreading on solid surfaces, enhancing the suspension stability of powders in liquid phases and preventing agglomeration and sedimentation. Additionally, this product maintains stable performance over a wide pH range and under various water quality conditions, being resistant to acids, alkalis, and hard water, thus imparting higher reliability to formulations.
PEG200MO is derived from natural fatty acids, with low irritation to skin and mucous membranes, offering mild usage characteristics. Its nonionic nature allows good compatibility with anionic, cationic, and other nonionic surfactants, flexibly meeting the formulation needs of multicomponent systems.
