A pressurized composition in an aerosol container capable of forming a spray upon release of pressure therefrom which composition is a liquid inside the container and forms a gel on contact with living tissue comprising by weight about 45 to 90 percent water, 3 to 50 percent propellant and 7 to 20 percent of a polyoxyethylene-polyoxypropylene copolymer of the formula: Y[(C3H6O)n(C2H4O)mH]x wherein Y is the residue of a water-soluble organic compound containing therein x active hydrogen atoms; n is an integer; x is an integer greater than 1; the value of n and x are such that the molecular weight of the oxypropylene groups is from about 3250 to 7500; and the value of m is such that the oxyethylene groups constitute about 45 to 90 percent by weight of the total compound and wherein the water/copolymer weight ratio is at least about 4.5:1.
