摘要： The present invention relates to a paraffin-in-water dispersion comprising - water, - a long-chain hydrocarbon or a mixture of a plurality of long-chain hydrocarbons, - at least one first surfactant having a hydrophilic radical having a chain length of at least (40) atoms, - at least one second surfactant having a hydrophilic radical having a chain length of at most (20) atoms, where - each of the surfactants present in the dispersion has a long-chain hydrophobic group having at least (14) carbon atoms in the chain, by which it is anchored on the paraffin droplets, and wherein - at least one of the surfactants mentioned is a nonionic surfactant and - at least one of the surfactants mentioned is an anionic surfactant bearing at least one carboxylate group. It preferably further comprises a third, nonionic surfactant which has a hydrophilic radical having a chain length of less than (20) carbon atoms. The invention also relates to a method for producing this dispersion.
