Abstract
Hydrophilic surfactant compositions are disclosed that include a surfactant component and a stabilizer component. The surfactant can be coated on a surface by depositing a surfactant solution on at least a portion of the surface, then drying the surfactant solution to form the dry coating. The surfactant compositions, when applied to a substrate, can provide a hydrophilic surface that retains its hydrophilic character over time, at elevated temperatures, or both.
