Emulsogen 5781 is a polymeric surfactant, particularly recommended to be used as as nonionic emulsifier in rolling emulsions.
Emulsogen 5781 is a perfect choice to stabilize a wide range of emulsions. The product forms clear solutions in all types of mineral oils, synthetic esters and vegetable oils. Due to its low HLB, Emulsogen 5781 does not form self-emulsifying systems.
