Abstract

An alcoholic foam composition, which can be dispensed as a foam via a pump-foam system contains a) at least 52 to ≦99 wt % of an alcohol or mixture of alcohols, b) a surfactant or a surfactant mixture, c) at least one polyalkylene glycol, d) optionally, at least one foam stabilizer, e) optionally, at least one member selected from the group consisting of cosmetic auxiliaries, adjuvants, active ingredients, and mixtures thereof, and f) optionally water. The surface tension of component b) lies in the range of ±15 dyn/cm of the surface tension of component a) or corresponds to the surface tension of component a), and the sum of components a) to f) is 100 wt % relative to the total quantity of the foam composition.
