A method for the production of spherical wax particles, which, in a liquid, mainly of water existing medium and stabilized dispersed, as well as for the use of such spherical wax particles in the aqueous medium
A method for the production of spherical wax particles, which, in a liquid under normal conditions, mainly of water existing medium and stabilized dispersed be present, in which casea) raw materials consisting of waxes, emulsifiers, optional auxiliaries and water in a container are heated under thorough mixing, so that solid raw materials are melted and therein a homogeneous emulsion is produced therefrom,b) then the emulsion high shear forces and / or turbulences in a device according to the principle of the high pressure expansion art, while a pressure of 300 bar is exposed andc), finally, the emulsion is cooled down, resulting in a stable dispersion with spherical wax particles with average particle diameters between 0,5 and 50 μm results.
