Field of the Invention The present invention relates to the use of an ethoxylated alkylamine to modify the surface tension of a plastic surface (e.g., for hydrophilization and for improving wettability). [Prior Art] • The plastic surface to which the surface tension is modified is hereinafter referred to as a polymer surface. The surface tension of the surface of the polymer is modified to, for example, change the shape of the water droplets on the surface of the polymer to wet a larger area. This involves hydrophilizing the surface of the polymer to achieve improved water wettability. This method increases the surface area of the water droplets and reduces the energy required to remove the droplets by drying, and allows the surface to dry more quickly. An example of such a modified surface is a plastic component that is horizontally mounted in a dishwasher. Known methods for modifying the surface tension of plastics are corona treatment and flame treatment and are used by Nentwig, Hanser Verlag in ''Kunststofffolien (Herstellen-Eigenschaften, Anwendungen)" [plastic film (manufacture, properties, applications) (Plastics films (production, properties, applications))] is described on page 159 and below. • There is a need for a method that is easy to use during the conventional processing of polymers and that can modify the surface tension of the surface of the polymer. It has been surprisingly found that certain ethoxylated alkylamines modify the surface tension of the polymer surface.
