Abstract of the Invention Aqueous polyethylene dispersions, suitable for improving the surface characteristics of glass, are disclosed. The dispersions contain 40 to 100 percent by weight, based on the polyethylene, of a mixture of a) amine oxides of the general formula R1CONH(CH2)n?(CH3)2 wherein R1 is alkyl with 7 to 17 carbon atoms; n is 2 or 3 and b) the salt of an amine of the general formula R2M[(C2H4O)mH]2 II with a physiological safe carboxylic acid, wherein R2 is alkyl with 8 to 18 carbon atoms and the sum of the units m is 20 to 100, the components a) and b) being present in a ratio by weight of 4 : 1 to 1: 1. The dispersions may be obtained by stirring a melt of the polyethylene,which contains component b), into water, which contains component a).
