Abstract: A liquid agent for de-icing and protecting against icing-up is described, by means of which it is possible, in particular, to free the metal surface of aircraft rapidly and completely from ice, hoar-frost, snow and the like, and to protect the surface against further build-up for a relatively long period. The agent is essentially composed of several components, namely of a) glycols, b) water, c) thickeners, d) substances insoluble in water, e) surface-active agents, f) corrosion inhibitors and g) alkaline compounds, in very specific quantities in each case, the quantity of the components a) and b) being at least 94%, relative to the total weight of the agent. Its pH value is 7.5 to 10.
