Claim 15:
16. A method of producing an aqueous wax dispersion according to claim 14 comprising at least the following steps:
providing a wax composition in a molten state, said wax composition comprising at least a first wax composition and Carnauba wax, wherein the first wax composition comprises:
linear and branched wax hydrocarbons having 15 to 110 carbon atoms;
oxidized hydrocarbons, and

said first wax composition characterized by
a congealing point from 68° C. to 110° C.,
an acid number of 3 to 30 mg KOH/g,
a saponification number of 20 to 90 mg KOH/g; and
a needle penetration at 25° C. of below 15 1/10 mm;
and wherein the first wax composition and the Carnauba wax are in a weight ratio of 1:9 to 9:1

adding water and the surfactant in any order to the molten wax composition,
emulsifying the components together in a high pressure homogenizer, an autoclave or with a ultrasonic sonotrode.
