Abstract

The invention provides hydroxyl-containing surfactants with low surface tension and provides for their use as surfactants in aqueous coating formulations, the surfactants being preparable by reacting one or more epoxides of formula (I)with at least one hydroxy compound of formula (II)and/or at least one, or two or more, amine(s) of formula (III)reacted in preferably either approximately equivalent amounts of hydroxy and/or amino groups with epoxide groups, or with an excess of hydroxy or amine hydrogen atoms, respectively.
