General description

Polyoxyethylene (40) stearate is a neutral surfactant.

Application

Polyoxyethylene (40) stearate has been used in a study to assess the phase behaviors of special hot microemulsion to produce drug-loaded nanostructured lipid carriers. It has also been used in a study to investigate its effects on multidrug resistance (MDR).
