The present invention relates to foamable oil-in-water emulsions containing: A) one or more emulsifiers, at least one of which is a non-ionic emulsifier, B) one or more cotensides, C) one or more oils, D) optionally, one or more polar solubilizers, E) optionally, auxiliary and additive substances, F) one or more surfactants, G) water, H) optionally, water-soluble substances, provided that the water content of the emulsion is ≥70% by weight and the concentration of surfactant(s) F) is from 0.01 to less than 10% by weight, each based on the entire emulsion. The invention further relates to a method for producing the oil-water emulsions according to the invention, to foams obtained from these oil-water emulsions, to a method for producing the foams, and to the application of the oil-water emulsions according to the invention and to the foams produced therefrom.
