Abstract

Machine dishwashing detergents containing builder(s), surfactant(s), and optionally further ingredients which comprise 0.1 to 50% by weight of one or more nonionic surfactants which, at a concentration of 0.1 g/l in distilled water, have a dynamic surface tension of less than 60 mNm−1 at a frequency of 1 Hz.
