At higher temperatures, the POE segment seems to tend to transfer from the aqueous phase to the oil-water interface, and the POE segment to leave the interface for the oil phase.
随着温度升高，环氧乙烷链段从水相向油-水界面转移，而环氧丙烷链段则部分脱离界面进入油相。

To the latter, the role of methyl oleate in influencing the partition of surfactant in oil phase and aqueous phase competes with its adsorption role at the interface.
